On the Twist Recovery Methodologies After Failure

In this paper, methodologies for investigating the effect of failures on the performance of manipulators are presented, and the correctional input for recovering the lost motion provided by the remaining joints, for minimum Euclidean norm of the correctional and the overall joint velocity vectors, are presented. The procedure is simulated to examine the norm of the overall input before and after a failure, as well as the norm of the correctional input.
