Real-time control of robots: Strategies for hardware and software development

A review of various strategies for hardware and software development of real-time controllers for commercial robots is presented. These developments, all depending on state-of-the-art hardware and software, are designed to correspond to specific research objectives. The Robotics and Automation Laboratory (RAL) TUNIS multiptocessor system, used to control a PUMA without VAL, is presented. The proposed scheme is suitable for implementing the computed torque technique, the feedback linearization technique, and various modern control methods applied to both joint and task space variables.
