Robot arm comprising an input module

A robotic arm having at least first and second robotic arm segments respectively, which are moveable relative to one another, and at least one manually operable robotic arm movement control element configured for generating robotic arm movement control signals for initiating and controlling the movement of the robotic arm on the basis of a user input supplied to the least one manually operable robotic arm movement control element, characterized in that said at least first and second robotic arm segments have a first arm module interface respectively onto which the manually operable robotic arm movement control element can be selectively mounted and wherein a movement of the robotic arm is effectuated, in at least one mode of operation, under control of said manually operable robotic arm movement control element and wherein the at least one manually operable robotic arm movement control element includes two interfaces and wherein one of said two input module interfaces is configured for being connected with the first robotic arm segment and the other of said two input module interfaces is configured for being connected with the second robotic arm segment.
