DESIGN AND SIMULATION OF A MICROPROCESSOR- BASED INDUSTRIAL ARM. A RESEARCH PROJECT MATERIAL ON COMPUTER SCIENCE
ABSTRACT
A system to control a hydraulic industrial arm using a4- bit microcomputer is described. A supervisory minicomputer can handle global routines such as science analysis and task and trajectory planning while the microcomputer attends to the control of the arm. The microcomputer monitors arm joint positions and sensors, and maintains current joint position when no motion is desired. The supervisory in the form of a sequence of macro- commands. The microcomputer interprets and executes the job and returns the final status of the arm to the minicomputer.
The designing of the microprocessor- based industrial arm will base on the component of the system used, the circuit analysis diagram and the flowchart which will help you to write program specification.
The result of the designing enabled us to achieve our purpose which we have described above. This include the industrial arm in motion- based industrial arm will base on the component of the system used, the circuit analysis diagram and the flowchart which will help you to write program specification.

CHAPTER ONE
THE PROBLEM AND ITS SETTING
INTRODUCTION
Most industrial arm system are driven from magnetic tape or paper tape. A few are driven by a computer which enables them to make decisions.
(1) Using the same computer handles task and trajectory planning as well as controlling the trajectory of the industrial arm system and hand by computer first calculates a trajectory and then executes it by driving the arm along it. Two exception to the kind of system architecture are the control system proposed for the Robot Popeye at the Charles stark draper laboratory.
(2) The stand ford research institute unmated control system is composed of a PDP-10 time-shared computers as a command computer,PDP-15 as a control computer and a Nova 1210 as a sensor.
(3) The system described here consist of a supervisory computer which handles scene analysis, task and trajectory planning routines and a microcomputer which control arm motions, the supervisory computer can be a minicomputer or a time- shared computer.
