An actuation block for a train of segments, that can be used as a manual interface terminating by a finger grip ( 31 ) of the user, comprises a base ( 1 ) fixed to the hand or arm of the user and two or three motors ( 5, 32 ) oriented so that their main extension direction, or the direction of their output shaft, is parallel to a first pivoting segment ( 16 ) of the train. The actuation block is thus compact. Applications may include control arms or, on the contrary, force return arms.
