Abstract

Hardware development was based on von Neumann’s scheme at the beginning. This approach has reached its physical limits. The development of new processors is slowing down and the use of only one processor will soon be past. The kernel of our multiprocessor laboratory robot controller is the transputer card with four IMS T805 transputers. The robot controller is connected to the microcomputer Motorola 68000 and over it to the analog current controllers for the 2 DOF SCARA type mechanism. The microcomputer Motorola 68000 will be soon replaced with the transputer based joint controllers. In solving problems with multiprocessor structures its very important how tasks are distributed among processors and how they communicate. The program model of the transputer based robot controller is presented with the System Architect package (CASE). All documentation for our robot controller is based on the reverse engineering approach.
