Darrick Addison (dtadd95@https://www.wendangku.net/doc/0b16426534.html,), Senior Software
Engineer/Consultant, ASC Technologies Inc. 01 Sep 2001 "A re-programmable, multifunctional manipulator designed to move material, parts, tools, or specialized devices through various programmed motions for the performance of a variety of tasks."
-- From the Robot Institute of America, 1979
Darrick Addison, an experienced developer in databases, networks, user interfaces, and embedded systems, introduces the field of robotics and the issues surrounding robotic systems. He covers mechanical design, sensory systems, electronic control, and software. He also discusses microcontroller systems, including serial and memory-mapped interfacing, and talks about some of the available open source software options.
The word "robot" originates from the Czech word for forced labor, or serf. It was introduced by playwright Karel Capek, whose fictional robotic inventions were much like Dr. Frankenstein's monster -- creatures created by chemical and biological, rather than mechanical, methods. But the current mechanical robots of popular culture are not much different from these fictional biological creations. Basically a robots consists of:
? A mechanical device, such as a wheeled platform, arm, or other construction, capable of interacting with its environment
?Sensors on or around the device that are able to sense the environment and give useful feedback to the device
?Systems that process sensory input in the context of the device's current situation and instruct the device to perform actions in response to the situation
In the manufacturing field, robot development has focused on engineering robotic arms that perform manufacturing processes. In the space industry, robotics focuses on highly specialized, one-of-kind planetary rovers. Unlike a highly automated manufacturing plant, a planetary rover operating on the dark side of the moon -- without radio communication -- might run into unexpected situations. At a minimum, a planetary rover must have some source of sensory input, some way of interpreting that input, and a way of modifying its actions to respond to a changing world. Furthermore, the need to sense and adapt to a partially unknown environment requires intelligence (in other words, artificial intelligence).
From military technology and space exploration to the health industry and commerce, the advantages of using robots have been realized to the point that they are becoming a part of our collective experience and every day lives.
They function to relieve us from danger and tedium:
?Safety:Robotics have been developed to handle nuclear and radioactive chemicals for many different uses including nuclear weapons, power plants, environmental cleanup, and the processing of certain drugs.
?Unpleasantness:Robots perform many tasks that are tedious and unpleasant, but necessary, such as welding or janitorial work.
?Repetition and precision: Assembly line work has been one of the mainstays of the robotics industry. Robots are used extensively in manufacturing and, more glamorously, in space exploration, where minimum maintenance requirements are emphasized.
Mechanical platforms -- the hardware base
A robot consists of two main parts: the robot body and some form of artificial intelligence (AI) system. Many different body parts can be called a robot. Articulated arms are used in welding and painting; gantry and conveyor systems move parts in factories; and giant robotic machines move earth deep inside mines. One of the most interesting aspects of robots in general is their behavior, which requires a form of intelligence. The simplest behavior of a robot is locomotion. Typically, wheels are used as the underlying mechanism to make a robot move from one point to the next. And some force such as electricity is required to make the wheels turn under command.
Motors
A variety of electric motors provide power to robots, allowing them to move material, parts, tools, or specialized devices with various programmed motions. The efficiency rating of a motor describes how much of the electricity consumed is converted to mechanical energy. Let's take a look at some of the mechanical devices that are currently being used in modern robotics technology.
DC motor:Permanent-magnet, direct-current (PMDC) motors require only two leads, and use an arrangement of fixed- and electro-magnets (stator and rotor) and switches. These form a commutator to create motion through a spinning magnetic field.
AC motor:AC motors cycle the power at the input-leads, to continuously move the field. Given a signal, AC and DC motors perform their action to the best of their ability.
Stepper motor:Stepper motors are like a brushless DC or AC motor. They move the rotor by applying power to different magnets in the motor in sequence (stepped). Steppers are designed for fine control and will not only spin on command, but can spin at any number of steps-per-second (up to their maximum speed).
Servomotors:Servomotors are closed-loop devices. Given a signal, they adjust themselves until they match the signal. Servos are used in radio control airplanes and cars. They are simple DC motors with gearing and a feedback control system.
Driving mechanisms
Gears and chains:Gears and chains are mechanical platforms that provide a strong and accurate way to transmit rotary motion from one place to another, possibly changing it along the way. The speed change between two gears depends upon the number of teeth on each gear. When a powered gear goes through a full rotation, it pulls the chain by the number of teeth on that gear.
Pulleys and belts:Pulleys and belts, two other types of mechanical platforms used in robots, work the same way as gears and chains. Pulleys are wheels with a groove around the edge, and belts are the rubber loops that fit in that groove.
Gearboxes:A gearbox operates on the same principles as the gear and chain, without the chain. Gearboxes require closer tolerances, since instead of using a large loose chain to transfer force and adjust for misalignments, the gears mesh directly with each other. Examples of gearboxes can be found on the transmission in a car, the timing mechanism in a grandfather clock, and the paper-feed of your printer.
Power supplies
Power supplies are generally provided by two types of battery. Primary batteries are used once and then discarded; secondary batteries operate from a (mostly) reversible chemical reaction and can be recharged several times. Primary batteries have higher density and a lower self-discharge rate. Secondary (rechargeable) batteries have less energy than primary batteries, but can be recharged up to a thousand times depending on their chemistry and environment. Typically the first use of a rechargeable battery gives 4 hours of continuous operation in an application or robot.
There are literally hundreds of types and styles of batteries available for use in robots. Batteries are categorized by their chemistry and size, and rated by their voltage and capacity. The voltage of a battery is determined by the chemistry of the cell, and the capacity by both the chemistry and size. See Table 1 for battery sizes.
ground. This way, the motor may dirty up one power source while the electronics can run off of the other. The electronics and the motors can also operate from different voltages.
Electronic control
There are two major hardware platforms in a robot. The mechanical platform of unregulated voltages, power and back-EMF spikes, and the electronic platform of clean power and 5-volt signals. These two platforms need to be bridged in order for digital logic to control mechanical systems. The classic component for this is a bridge relay. A control signal generates a magnetic field in the relay's coil that physically closes a switch. MOSFETs, for example, are highly efficient silicon switches, available in many sizes like the transistor that can operate as a solid state relay to control the mechanical systems.
On the other hand, larger sized robots may require a PMDC motor in which the value of the MOSFET's "on" resistance Rds(on) results in great increases in the heat dissipation of the chip, thereby significantly reducing the chip's heat temperature. Junction temperatures within the MOSFET and the coefficients of conduction of the MOSFET package and heat sink are other important characteristics of PMDC motors.
There are two broad families of transistor: bipolar junction transistors (BJT) and field-effect transistors (FET). In BJT devices, a small current flow at the base moderates a much larger current between the emitter and collector. In FET devices, the presence of an electrical field at the gate moderates the flow between the source and drain.
Sensors
Robots react according to a basic temporal measurement, requiring different kinds of sensors.
In most systems a sense of time is built-in through the circuits and programming. For this to be productive in practice, a robot has to have perceptual hardware and software, which updates quickly. Regardless of sensor hardware or software, sensing and sensors can be thought of as interacting with external events (in other words, the outside world). The sensor measures some attribute of the world. The term transducer is often used interchangeably with sensor. A transducer is the mechanism, or element, of the sensor that transforms the energy associated with what is being measured into another form of energy. A sensor receives energy and transmits a signal to a display or computer. Sensors use transducers to change the input signal (sound, light, pressure, temperature, etc.) into an analog or digital form capable of being used by a robot.
Logical sensors:One powerful abstraction of a sensor is a logical sensor, which is a unit of sensing or module that supplies a particular percept. It consists of the signal processing, from the physical sensor, and the software processing needed to extract the percept.
Proprioceptive sensors:Proprioception is dead reckoning, where the robot measures a signal originating within itself.
Proximity sensors:A proximity sensor measures the relative distance between the sensor and objects in the environment.
Infrared (IR) sensors:Another type of active proximity sensor is an infrared sensor. It emits near-infrared energy and measures whether any significant amount of the IR light is returned.
Bump and feeler sensors:Another popular class of robotic sensing is tactile, or touch-based, done with a bump and feeler sensor. Feelers or whiskers are constructed from sturdy wires. A bump sensor is usually a protruding ring around the robot consisting of two layers.
Microcontroller systems
Microcontrollers (MCUs) are intelligent electronic devices used inside robots. They deliver functions similar to those performed by a microprocessor (central processing unit, or CPU) inside a personal computer. MCUs are slower and can address less memory than CPUs, but are designed for real-world control problems. One of the major differences between CPUs and MCUs is the number of external components needed to operate them. MCUs can often run with zero external parts, and typically need only an external crystal or oscillator.
There are four basic aspects of a microcontroller: speed, size, memory, and other. Speed is designated in clock cycles, and is usually measured in millions of cycles per second (Megahertz, MHz). The use of the cycles varies in different MCUs, affecting the usable speed of the processor. Size specifies the number of bits of information the MCU can process in one step -- the size of its natural cluster of information. MCUs come in 4-, 8-, 16-, and 32-bits, with 8-bit MCUs being the most common size. MCUs count most of their ROM in thousands of bytes (KB) and RAM in single bytes. Many MCUs use the Harvard architecture, in which the program is kept in one section of memory (usually the internal or external SRAM). This in turn allows the processor to access the separate memories more efficiently.
The fourth aspect of microcontrollers, referred to as "other", includes features such as a dedicated input device that often (but not always) has a small LED or LCD display for output. A microcontroller also takes input from the device and controls it by sending signals to different components in the device. Also the program counter keeps track of which command is to be executed by the microcontroller.
R/C Servos:Servomotors, used in radio-controlled models (cars, planes, etc.) are useful in many kinds of smaller robots, because they are compact and quite inexpensive. The servomotors themselves have built-in motor, gearbox, position-feedback mechanisms and controlling electronics. Standard radio control servomotors which are used in model airplanes, cars and boats are useful for making arms, legs and other mechanical appendages which move back and forth rather than rotating in circles.
Animatronic systems
Animatronic systems are robotic systems which mimic and look like humans. An android is an anthropomorphic robot -- in other words, a robot that looks like a human.
Pneumatics:Pneumatics is the name for fluid power used in a large number of commercial robots. Pneumatics are also used in a variety of animatronic systems that fall under the category of fluid power. A more well known branch of fluid power is hydraulics.
source robot control software
OROCOS (Open RObot COntrol Software) is an effort to start up an open source
robot control software project. Broad discussions are being held about what experiences, code and tools can be re-used from other projects, what open standards should be integrated into the project and what organizational structure is most appropriate for the project. Goals of the project are to develop robot control software as follows:
?Under open source and/or free software license(s)
?As modular as possible
?Of the highest quality (from both technical and software engineering perspectives)
?Independent of (but compatible with) commercial robot manufacturers
?For all sorts of robotic devices and computer platforms
?Localized for all programming languages
?Featuring configurable software components for kinematics, dynamics, planning, sensing, control, hardware interfacing, etc.
The project aims to become more than just a copy of existing commercial robot controllers or robot simulation/programming packages. The OROCOS project wants to develop shareable libraries, stand-alone components (sometimes referred to as software agents), and a configurable run-time environment from which to eliminate and control all distributed robotics systems. These types of projects are useful in several ways:
?For re-using code
?For use as an independent sub-system
?For copying their organizational structure
?For learning from the experience of managing an open source project
?For designing and developing extensible and reusable software Open source matrix libraries
The following are open source matrix libraries that satisfy the above-mentioned requirements. Octave is recommended, since it is GPL-licensed and delivers all required functionality.
GNU Octave: GNU Octave is a high-level language, primarily intended for numerical computations. It provides a convenient command line interface for solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with Matlab. It is easily extensible and customizable via user-defined functions written in Octave's own language, or using dynamically loaded modules written in C++, C, Fortran, or other languages.
GNU Octave is freely distributed software. You may redistribute it and/or modify it under the terms of the GNU General Public License (GPL) as published by the Free Software Foundation. GSL (GNU Scientific Library)GSL is an ongoing
effort to develop a modern extensive and ANSI C library for numerical computing. The GNU Scientific Library (GSL) is a collection of routines for numerical computing. The routines are written from scratch by the GSL team in ANSI C, and are meant to present a modern Applications Programming Interface (API) for C programmers, while allowing wrappers to be written for very high level languages.
GSL is free software. It is distributed under the terms of the GNU General Public License. Real time kernels
Real-Time Linux (RTLinux)RTLinux(TM) is a hard real-time operating system that handles time-critical tasks and runs Linux as its lowest priority execution thread. In RTLinux, the kernel shares one or more processors with standard Linux. This allows the system to run accurately timed applications performing data acquisition, systems control and robotics, while still serving as a standard Linux workstation. https://www.wendangku.net/doc/0b16426534.html, is the non-commercial RTLinux site for the open source user and developer community. eCos (embedded Configurable operating system): eCos is an open source real-time operating system for deeply embedded applications. It meets the requirements of the embedded space that Linux cannot yet reach. Linux currently scales upwards from a minimal size of around 500 kilobytes of kernel and 1.5MB of RAM, before taking into consideration application and service requirements. RTEMS (GPL License): RTEMS is an open source real-time operating system and environment for C, C++ and Ada95. It is distributed under the terms of the GNU General Public License.
Utilities and tools
ROBOOP (A robotics object oriented package in C++):This package is an object-oriented toolbox in C++ for robotics simulation. CORBA: A real-time communications and object request broker software package for embedding distributed software agents. Each independent piece of software registers itself and its capabilities to the ORB, by means of an IDL (Interface Definition Language).
TANGO/TACO:This software might be useful for controlling a robotics system with multiple devices and tools. TANGO is an object oriented control system based on CORBA. Device servers can be written in C++ or Java. TACO is object oriented because it treats all(physical and logical) control points in a control system as objects in a distributed environment. All actions are implemented in classes. New classes can be constructed out of existing classes in a hierarchical manner, thereby ensuring a high level of software reuse. Classes can be written in C++, in C (using a methodology called Objects in C), in Python or in LabView (using the G programming language).
TACO was designed to be portable and runs on a large number of platforms (for example, Linux, Solaris, HP-UX, Windows/NT, Windows/95, and OS9).
Controllers
Task Control Architecture: The Task Control Architecture (TCA) simplifies building task-level control systems for mobile robots. "Task-level" refers to the integration and coordination of perception, planning, and real time control to achieve a given set of goals (tasks). TCA provides a general control framework, and is intended to control a wide variety of robots. TCA provides a high-level machine-independent method for
passing messages between distributed machines (including between Lisp and C processes). TCA provides control functions, such as task decomposition, monitoring, and resource management, that are common to many mobile robot applications.
EMC (Enhanced Machine Controller): The EMC software is based on the NIST Real time Control System (RCS) methodology, and is programmed using the NIST RCS Library. The RCS Library eases the porting of controller code to a variety of UNIX and Microsoft platforms, providing a neutral application programming interface (API) to operating system resources such as shared memory, semaphores and timers. The EMC software is written in C and C++, and has been ported to the PC Linux, Windows NT, and Sun Solaris operating systems.
Darwin2K: Darwin2K is a free, open source toolkit for robot simulation and automated design. It features numerous simulation capabilities and an evolutionary algorithm capable of automatically synthesizing and optimizing robot designs to meet task-specific performance objectives.
Languages
RoboML (Robotic Markup Language): RoboML is used for standardized representation of robotics-related data. It is designed to support communication language between human-robot interface agents, as well as between robot-hosted processes and between interface processes, and to provide a format for archived data used by human-robot interface agents.
ROSSUM: A programming and simulation environment for mobile robots. The Rossum Project is an attempt to help collect, develop, and distribute software for robotics applications. The Rossum Project hopes to extend the same kind of collaboration to the development of robotic software.
XRCL (Extensible Robot Control Language): XRCL (pronounced zircle) is a relatively simple, modern language and environment designed to allow robotics researchers to share ideas by sharing code. It is an open source project, protected by the GNU Copyleft.
Open System Architecture for Controls within Automation Systems (OSACA): OSACA is a joint European project that aims to improve the competitiveness of the manufacturers of machine tools and control systems in the world market. The main goal of the project is to specify system architecture for open control systems, which is manufacturer independent.
Summary
The field of robotics has created a large class of robots with basic physical and navigational competencies. At the same time, society has begun to move towards incorporating robots into everyday life, from entertainment to health care. Moreover, robots could free a large number of people from hazardous situations, essentially allowing them to be used as replacements for human beings. Many of the applications being pursued by AI robotics researchers are already fulfilling that potential. In addition, robots can be used for more commonplace tasks such as janitorial work. Whereas robots were initially developed for dirty, dull, and dangerous applications, they are now being considered as personal assistants. Regardless of application, robots will require more rather than less intelligence, and will thereby have a significant impact on our society in the future as technology expands to new horizons.

中英文对照资料外文翻译文献 FEM Optimization for Robot Structure Abstract In optimal design for robot structures, design models need to he modified and computed repeatedly. Because modifying usually can not automatically be run, it consumes a lot of time. This paper gives a method that uses APDL language of ANSYS 5.5 software to generate an optimal control program, which mike optimal procedure run automatically and optimal efficiency be improved. 1）Introduction Industrial robot is a kind of machine, which is controlled by computers. Because efficiency and maneuverability are higher than traditional machines, industrial robot is used extensively in industry. For the sake of efficiency and maneuverability, reducing mass and increasing stiffness is more important than traditional machines, in structure design of industrial robot. A lot of methods are used in optimization design of structure. Finite element method is a much effective method. In general, modeling and modifying are manual, which is feasible when model is simple. When model is complicated, optimization time is longer. In the longer optimization time, calculation time is usually very little, a majority of time is used for modeling and modifying. It is key of improving efficiency of structure optimization how to reduce modeling and modifying time. APDL language is an interactive development tool, which is based on ANSYS and is offered to program users. APDL language has typical function of some large computer languages. For example, parameter definition similar to constant and variable definition, branch and loop control, and macro call similar to function and subroutine call, etc. Besides these, it possesses powerful capability of mathematical calculation. The capability of mathematical calculation includes arithmetic calculation, comparison, rounding, and trigonometric function, exponential function and hyperbola function of standard FORTRAN language, etc. By means of APDL language, the data can be read and then calculated, which is in database of ANSYS program, and running process of ANSYS program can be controlled.

INTELLIGENT VEHICLE Our society is awash in “machine intelligence” of various kinds.Over the last century, we have witnessed more and more of the “drudgery” of daily living being replaced by devices such as washing machines. One remaining area of both drudgery and danger, however, is the daily act ofdriving automobiles 1.2 million people were killed in traffic crashes in 2002, which was 2.1% of all globaldeaths and the 11th ranked cause of death . If this trend continues, an estimated 8.5 million people will be dying every year in road crashes by 2020. In fact, the U.S. Department of Transportation has estimated the overall societal cost of road crashes annually in the United States at greater than $230 billion. When hundreds or thousands of vehicles are sharing the same roads at the same time, leading to the all too familiar experience of congested traffic. Traffic congestion undermines our quality of life in the same way air pollution undermines public health.Around 1990, road transportation professionals began to apply them to traffic and road management. Thus was born the intelligent transportation system(ITS). Starting in the late 1990s, ITS systems were developed and deployed. In developed countries, travelers today have access to signifi-cant amounts of information about travel conditions, whether they are driving their own vehicle or riding on public transit systems.

译文资料： 机器人 首先我介绍一下机器人产生的背景，机器人技术的发展，它应该说是一个科学技术发展共同的一个综合性的结果，同时，为社会经济发展产生了一个重大影响的一门科学技术，它的发展归功于在第二次世界大战中各国加强了经济的投入，就加强了本国的经济的发展。另一方面它也是生产力发展的需求的必然结果，也是人类自身发展的必然结果，那么随着人类的发展，人们在不断探讨自然过程中，在认识和改造自然过程中，需要能够解放人的一种奴隶。那么这种奴隶就是代替人们去能够从事复杂和繁重的体力劳动，实现人们对不可达世界的认识和改造，这也是人们在科技发展过程中的一个客观需要。 机器人有三个发展阶段，那么也就是说，我们习惯于把机器人分成三类，一种是第一代机器人，那么也叫示教再现型机器人，它是通过一个计算机，来控制一个多自由度的一个机械，通过示教存储程序和信息，工作时把信息读取出来，然后发出指令，这样的话机器人可以重复的根据人当时示教的结果，再现出这种动作，比方说汽车的点焊机器人，它只要把这个点焊的过程示教完以后，它总是重复这样一种工作，它对于外界的环境没有感知，这个力操作力的大小，这个工件存在不存在，焊的好与坏，它并不知道，那么实际上这种从第一代机器人，也就存在它这种缺陷，因此，在20世纪70年代后期，人们开始研究第二代机器人，叫带感觉的机器人，这种带感觉的机器人是类似人在某种功能的感觉，比如说力觉、触觉、滑觉、视觉、听觉和人进行相类比，有了各种各样的感觉，比方说在机器人抓一个物体的时候，它实际上力的大小能感觉出来，它能够通过视觉，能够去感受和识别它的形状、大小、颜色。抓一个鸡蛋，它能通过一个触觉，知道它的力的大小和滑动的情况。第三代机器人，也是我们机器人学中一个理想的所追求的最高级的阶段，叫智能机器人，那么只要告诉它做什么，不用告诉它怎么去做，它就能完成运动，感知思维和人机通讯的这种功能和机能，那么这个目前的发展还是相对的只是在局部有这种智能的概念和含义，但真正完整意义的这种智能机器人实际上并没有存在，而只是随着我们不断的科学技术的发展，智能的概念越来越丰富，它内涵越来越宽。 下面我简单介绍一下我国机器人发展的基本概况。由于我们国家存在很多其

A SIMPLE ARCHITECTURE FOR IN-PIPE INSPECTION ROBOTS Mihaita HORODINCA, Ioan DOROFTEI, Emmanuel MIGNON, André PREUMONT Active Structures Laboratory UNIVERSITE LIBRE DE BRUXELLES Av. F. D. Roosevelt 50, cp 165/42, Brussels, Belgium Phone: (32)2-6504663 Fax: (32)2-6504660 e-mail: andre.preumont@ulb.ac.be Abstract: The paper presents an original robot architecture for in-pipe inspection. The robot consists of two parts articulated with a universal joint. One part is guided along the pipe by a set of wheels moving parallel to the axis of the pipe, while the other part is forced to follow an helical motion thanks to tilted wheels rotating about the axis of the pipe. A single motor is placed between the two bodies to produce the motion. All the wheels are mounted on a suspension to accommodate for changing tube diameter and curves in the pipe. The robot is autonomous and carries its own batteries and radio link. Four different prototypes have been constructed for pipe diameters of 170, 70 and 40 mm, respectively. For smaller diameters, the batteries and the radio receiver may be placed on an additional body attached to the others. The autonomy of the prototypes is about 2 hours. This architecture is very simple and the rotary motion can be exploited to carry out scrubbing or inspection tasks. Keywords: Autonomous mobile robot, In-pipe inspection, Helical motion Introduction Pipe inspection robots have been studied for a long time, and many original locomotion concepts have been proposed to solve the numerous technical difficulties associated with the change in pipe diameter, curves and energy supply. Although an exhaustive review of the literature is impossible due to the limited space available, a few broad categories can be identified: (i) For small size, many projects follow the earthworm principle consisting of a central part moving axially while the two end parts are provided with blocking devices connected temporarily to the pipe. Pneumatic versions of this concept have been proposed (e.g. [1]), but they require an umbilical for power. For smaller diameter (10 mm or less), a piezoelectric actuation has been considered, according to the inchworm principle, or according to an inertial locomotion driven by a saw-tooth wave voltage [2], or using vibrating fins with differential friction coefficients [3]. (ii) For medium size piping, classical electromechanical systems have been proposed with various architectures involving wheels and tracks, with more or less complicated kinematical structures, depending on the diameter adaptability and turning capability (e.g. [4,5]). (iii) For large pipes, walking tube crawlers have also been proposed [6].

多自由度步行机器人 摘要在现实生活中设计一款不仅可以倒下而且还可以站起来的机器人灵活智能机器人很重要。本文提出了一种两臂两足机器人,即一个模仿机器人,它可以步行、滚动和站起来。该机器人由一个头,两个胳膊和两条腿组成。基于远程控制,设计了双足机器人的控制系统,解决了机器人大脑内的机构无法与无线电联系的问题。这种远程控制使机器人具有强大的计算头脑和有多个关节轻盈的身体。该机器人能够保持平衡并长期使用跟踪视觉,通过一组垂直传感器检测是否跌倒,并通过两个手臂和两条腿履行起立动作。用实际例子对所开发的系统和实验结果进行了描述。 1 引言随着人类儿童的娱乐,对于设计的双足运动的机器人具有有站起来动作的能力是必不可少。 为了建立一个可以实现两足自动步行的机器人,设计中感知是站立还是否躺着的传感器必不可少。两足步行机器人它主要集中在动态步行,作为一种先进的控制问题来对待它。然而,在现实世界中把注意力集中在智能反应,更重要的是创想,而不是一个不会倒下的机器人,是一个倒下来可以站起来的机器人。 为了建立一个既能倒下又能站起来的机器人,机器人需要传感系统就要知道它是否跌倒或没有跌倒。虽然视觉是一个机器人最重要的遥感功能,但由于视觉系统规模和实力的限制,建立一个强大的视觉系统在机器人自己的身体上是困难的。如果我们想进一步要求动态反应和智能推理经验的基础上基于视觉的机器人行为研究,那么机器人机构要轻巧足以够迅速作出迅速反应,并有许多自由度为了显示驱动各种智能行为。至于有腿机器人,只有一个以视觉为基础的
小小的研究。面临的困难是在基于视觉有腿机器人实验研究上由硬件的显示所限制。在有限的硬件基础上是很难继续发展先进的视觉软件。为了解决这些问题和推进基于视觉的行为研究,可以通过建立远程脑的办法。身体和大脑相连的无线链路使用无线照相机和远程控制机器人,因为机体并不需要电脑板,所以它变得更加容易建立一个有许多自由度驱动的轻盈机身。 在这项研究中,我们制定了一个使用远程脑机器人的环境并且使它执行平衡的视觉和起立的手扶两足机器人,通过胳膊和腿的合作,该系统和实验结果说明如下。图 1 远程脑系统的硬件配置图 2 两组机器人的身体结构 2 远程脑系统 远程控制机器人不使用自己大脑内的机构。它留大脑在控制系统中并且与它用无线电联系。这使我们能够建立一个自由的身体和沉重大脑的机器人。身体和大脑的定义软件和硬件之间连接的接口。身体是为了适应每个研究项目和任务而设计的。这使我们提前进行研究各种真实机器人系统。 一个主要利用远程脑机器人是基于超级并行计算机上有一个大型及重型颅脑。虽然硬件技术已经先进了并拥有生产功能强大的紧凑型视觉系统的规模,但是硬件仍然很大。摄像头和视觉处理器的无线连接已经成为一种研究工具。远程脑的做法使我们在基于视觉机器人技术各种实验问题的研究上取得进展。 另一个远程脑的做法的优点是机器人机体轻巧。这开辟了与有腿移动机器人合作的可能性。至于动物,一个机器人有 4 个可以行走的四肢。我们的重点是基于视觉的适应行为的4肢机器人、机械动物,在外地进行试验还没有太多的研究。 大脑是提出的在母体环境中通过接代遗传。大脑和母体可以分享新设计
