[ contact / participants ]

a real-time distributed heterogeneous architecture for the control of machine tools and robots

Objectives and Approach

The planned control system will be a mix of transputers and digital signal processors (DSPs). While transputers are optimised for parallel processing and communication, DSPs are optimised for servo-control, sensor interpretation and, more recently, communication capabilities.

Parallelism within the architecture will be coarse-grained. Everything will be programmed in C or C++ and designed to be portable across all processors. This is achieved by having a common real-time kernel.

The final demonstration will be the full control of a complex flexible manufacturing cell. A multi-axis numerically-controlled press brake with a 5-axis robot will be integrated with the machine, together with an in-process measuring system and peripheral equipment.
