Abstract

Singularity is an inherent problem and an important obstacle to be overcome in robotic kinematics. A robot will lose one or more degrees of freedom (DOF), and joint velocities approach infinite, leading to control instability near singularity configuration. A strategy for stabilizing robot rate control near or at singularity (degenerate) configuration using phantom DOF is proposed. The phantom DOF is considered as part of a robot kinematic velocity model and is activated only when the joint velocity exceeds its limit or at singularity configurations. A numerical illustration of singularity control for a 5-DOF gantry robot is discussed.
