Abstract : This paper proposes an easy-to-implement set-point control of robot end-effector pose using dual quaternion representation. A dual quaternion error invariant to the choice of the reference coordinate system is defined and the stability of two different kinds of controllers, one based on a constrained-Jacobian transpose and the other on a constrained-Jacobian pseudoinverse, both derived in dual quaternion space, is proved using Lyapunov theory. In addition, this paper describes a simple method to tune the proposed controllers from a practical and pragmatic point of view. Experiments with a 6-axis industrial robot are shown in order to highlight the efficiency of the method and the performance of the developed controllers.
