<p>Provided is an arm structure for a robot which can favourably carry out jobs which are typically performed by humans. By determining the length (L) of the arm (4) and the height (Ho) of the axis of rotation (C) of the arm in such a manner that a range of rotational motion of the arm in accessing the region can be covered by a range in which the fore-and-aft distance to the tip of the arm can be linearly approximated, even though the trajectory of the arm (4) is approximated by a line (PQ), the error (D) in the distance to the object can be limited within a prescribed range, and the practicality and economy of computation can be achieved at the same time. <IMAGE></p> |
