摘要： A robot manipulator which includes an upper arm having a wrist coupled to one end of the upper arm. The wrist includes at least three rotational axes of articulation with one of the rotational axes offset from an intersection of the other two rotational axes. Three twist angles are formed between the respective rotational axes. The value of these twist angles is optimized to orientate the three rotational axes of articulation in a configuration minimizing the space which the robot manipulator cannot reach.
