In this paper, we propose a new method of grasp planning for a manipulator with a parallel jaw gripper in obstacle environment. We consider collision avoidance as a problem of motion planning in obstacle environments. In general, however, a redundant degree of freedom (DOF) is required to avoid obstacle and to grasp. In our proposal, we pay attention to redundant DOF in a grasping pose. Using redundant DOF in a grasping pose, a manipulator can avoid obstacles and grasp a target object. It does not require any redundant manipulators.
