Abstract

A robot comprises at least one articulate arm having members including a base, an end effector and a plurality of links, wherein each link is movably connected to two others of said members by respective joints, at least one sensor for detecting an external force acting on any one of the members, and a controller for controlling movements of the joints, so as to move the end effector along a pre-programmed path. In case of the sensor detecting an external force, the controller is adapted to adopt a first release strategy for escaping from the external force, to evaluate whether the first strategy is successful, and if not, to adopt a second release strategy.
