In our previous work we proposed two approaches to singularity treatment: one is based on a null space notation, and the other on an adjoint Jacobian. We call these approaches as the singularity-consistent approach. Both meth-ods guarantee the direction of motion in the whole work space, without producing an infeasible joint velocity. The performance has been experimentally verified with 3-DOF manipulators. In this paper, we apply the method to a real telerobot system with a non-redundant 6-DOF manipulator as the slave. We analyze the velocity relation at the singularities of this manipulator, and discuss several important implementation issues. The experimental results show that the 6-DOF manipulator can be operated safely with feasible joint velocity and without any error in the direction of motion.
