Stability of Haptic Obstacle Avoidance and Force Interaction

Johansson, Rolf LU orcid ; Annerstedt, Magnus and Robertsson, Anders LU (2009) 2009 IEEE/RSJ International Conference on Intelligent Robots and Systems p.3238-3243
Abstract
Stability problems associated with haptics and robot control with obstacle avoidance are analyzed. Obstacle avoidance algorithms are revised to accomplish stable redesign using absolute stability and passivity theory. A modification of potential functions for haptic rendering and obstacle avoidance allowing stable operation for high stiffness is proposed. The modification leads to velocity-dependent potential-like repulsive stable haptic force interaction with obstacles. Using strictly positive real re-design, stable force interaction can be provided also for high stiffness of manipulated objects or obstacles.
