We have proposed a real-time self-collision avoidance motion generation method for the mobile manipulator which is used for human-robot cooperation using "RoBE (Representation of Body by Elastic elements)". Furthermore, we have proposed the cooperating motion generation method which considers range of joint movement of the robot to deal with environmental/task constraints in human-robot cooperation. In this paper, we apply the proposed cooperative motion generation method to the real human-friendly robot referred to as "MR Helper". Because of the consideration of range of joint movement, the cooperative motions which could deal with task/environmental constraints could be generated on MR Helper while cooperating with a human. Some experiments are also done for illustrating the validity of the proposed cooperative motion generation method.
