A number of tools have been developed for automating the partitioning of control algorithms as a number of parallel tasks and, for the scheduling of these on a transputer-based system. Strategies of dynamic and static task allocation have been implemented and their features described. The tools permit simulation and evaluation of strategies, by displaying processor activity and performance.

control of a robot in any environment requires a range of complicated processing tasks. Cooperation with another robot introduces greater flexibility with further complication of the existing tasks and addition of new tasks required for cooperation. This paper shall examine the software and hardware architecture for such a system.

This paper describes research into the specification, design and implementation of real-time synchronisation and control software for a transputer-controlled, modular, multi-axis, independently driven, high-speed, packaging machine under normal and abnormal conditions. The research has already demonstrated the feasibility of using independent drives and software-based controllers for the synchronisation of both intermittent and continuous motions in applications at the boundary of existing technology.

Techniques for implementing an aircraft simulation and control system on a network of transputers are described. Different parallelisation approaches are shown to be appropriate within each of the major constituent processes. The task of atmospheric turbulence simulation is used to illustrate the procedure.

The functions of a robot controller can consist of planning, organisation, coordination and decision making at the top of control hierarchy and, joint angle control at the bottom end. Partition of the computational tasks between various independent processors, which can operate in parallel and communicate with each other when necessary, can help alleviate the burden and allow real-time implementation of a desired control algorithm. For control problem decomposition, although some parts of the algorithm can be considered to be efficiently mapped to a standard parallel architecture, a better performance can be achieved, by exploiting the inherent parallelism of the algorithm first and then devising a suitable processor topology, which matches the number of processes and has identical communication structures, in relation to the developed parallel algorithm. The transputer, being general purpose, capable of high speed processing with extensive capabilities is a relatively low cost processor which suitably fulfills the robot control computational requirements.

System simulation involves the construction of a computational analogue of a physical system - a process which has traditionally been associated with intemperate demands on processing time. Complex large-scale plant simulators and process mimics are almost commonplace in some high-technology industries. In such settings, simulation may be used in both the design and validation of novel control strategies, as well as forming part of an operator training programme, or in cause-consequence diagnostics.

A parallel color image processing system for grading fresh agricultural products is described in this paper. The system uses a transputer array to process data at a rate of 80 objects per second. It is also provided with debug buffer which allows uninterrupted systems operation. Some of the system's other features are a data magazine module, a chaincoder module, a task allocation module and a postal service module.
