Abstract

The design and implementation of a microprocessor-based system to control the interaction forces between a five-axis articulated robot and a workpiece is described. The control system worked in parallel with a robot controller by calculating position corrections that allowed forces to be controlled in the desired manner. These corrections were successfully interfaced to the controller’s position control loop on an individual-axis level. Stable force-control algorithms were designed in spite of limitations imposed by flexibility in the robot drive train. For multi-degree-of-freedom force control, it is shown that each axis can be considered autonomous, obviating the need for a multivariable a..
