Abstract
Title: Motion transmission system and method and robot comprising such a system. Motion transmission system, comprising a driving part (2) having a driving shaft (11) configured to be driven in rotation about a first axis (X), at least one driven part (4) and at least one transmission device (20) configured to drive said at least one driven part (4) in rotation about a second axis (Y), the transmission device (20) comprising at least one drive pinion (30 to 31) configured to be driven in rotation about a third axis of rotation (Z) and at least one locking screw (40, 41) meshing said at least one drive pinion (30 to 31), said at least one locking screw (40,41) being mounted to rotate about a fourth axis (W) and configured such that a rotation of said at least one drive pinion (30 to 31) about the third axis (Z) cannot cause said at least one locking screw (40, 41) to rotate about the fourth axis (W), the transmission device (20) further comprising at least one motor (50, 51), referred to as the control motor, configured to modify the rotational speed of said at least one locking screw (40, 41) about the fourth axis (W) so as to modify the rotational speed of said at least one driven part (4) about the second axis (Y).
