Control system of robot

Abstract: PURPOSE:To attain a teaching work simply in a short time without mistake by representing a plurality of robot service codes with a macrocode. CONSTITUTION:After the end of teaching work, the reproduction mode is taken. In the reproduction mode, when a robot service request signal RSR is generated from a machine tool, a robot controller RBC reads out a robot command data from a teaching memory TPM and executes the processing in accordance with the data for the execution of the specified service to the robot RBT. When the macrocode is read out from a memory TPM, a processing unit PU discriminates the code, reads a robot service code in response to the macrocode from a corresponding table MCT and sets the result to a work memory WKM. After the end of all the processings to the macrocode, the robot command data is read out of the memory TPM again and the similar processings are done afterward.

Control of a flexible robot arm

Abstract: Exact equations of motion of an arm with known parameters were developed and analyzed preparatory to designing control systems for robotic manipulators. The design of an experimental one-link arm for testing control designs is presented.

The blue-collar robot: The machine shop and the assembly line will be early beneficiaries of advanced robotic systems

Abstract: Discusses the future prospects for industrial robot systems predicting a high rate of growth through the 1980's.

Industrial Robots: Today And Tomorrow

Abstract: This paper presents an overview of industrial robots, for those who work outside of robotics but are interested in robots and how they are used by industry. Areas to be discussed are: Basic robotics, definitinon of robot, composition of robots, types of robots; Current application of typical uses of each type of robot; Advanced robotics, systems, controls, vision, and future developments.© (1980) COPYRIGHT SPIE--The International Society for Optical Engineering.

The prospect of an under wa ter na val robot

Abstract: This paper explores the concept of an underwater robot manipulator mounted on an unmanned submersible for the purpose of doing some undersea tasks of interest to the U.S. Navy. The robot concept is compared with other methods of doing work underwater and its strengths and weaknesses are enumerated. Such a robot would be able to do only simple, well-defined tasks, but it would probably be the most economical way of doing those jobs which are within its competence. The jobs which such a device might be able to do are listed and evaluated in terms of how easy or difficult they are for a robot to do. From this analysis some conclusions are drawn about what capabilities are needed in such a robot. It is concluded that speed of operation is not critical (In contrast to robots which are intended for industrial jobs), but that the ability to cope with unexpected conditions and to recover from mistakes is very important. Next, existing robot technology and past research***are discussed and evaluated in terms of the needs of an underwater naval robot. Gaps in the technology are identified, and, finally, me suggestions for research are given.

A semi‐autonomous remote controlled mobile robot

Abstract: Mobile robots offer more flexibility and scope than the fixed single arm type. French researchers are putting considerable effort into developing such devices and here results of their efforts are described.

Comparative evaluation of industrial robot accuracy

Abstract: The use of industrial robots has considerably increased in the last few years. The specification of the characteristics of such devices, however, is often confusing. Guidelines for standerdising the description of the characteristics of such devices are therefore desirable, so that different devices can be compared. This article describes a test program for industrial robots and introduces the most important variables and methods for measuring them. The results from assessing devices demonstrate the differences between various • types.

Motion control system development for a mobile robot

Abstract: Problems associated with the development of the motion control system for automatic mobile robots are discussed. The investigations have been performed with the breadboards of six-legged walking robot and automatic robot moving on wheels. Some results are presented.

Robot use in manufacturing

Abstract: Robots entered the English vocabulary with the translation of Karel Capek’s play R.U.R. (Rossum’s Universal Robots) in 1923. Capek was a Czech, and in his native language the word robot simply meant a worker. In the play, robots were the humanoid creations of Rossum and his son, constructed in the fond hope that they would perform obediently in the service of man. Now, thanks to Capek and a generation of science fiction writers, everyone knows what a robot is. The popular conception is a mechanical man, crammed full of near-miraculous components, and capable of clumsy imitations of human actions and speech. They are generally thought to combine superhuman strength with subhuman intelligence. Robots are often endowed with sinister intentions, so that the specter of a robot army marching against mankind has been a popular recurring theme in science fiction.
