Manipulator and manipulator system

A manipulator, comprising:

• an operating assembly operated by an operator;
• a moving assembly operated by the operating assembly;
• a transmitting assembly including an operating-side pulley that rotates in association with operation of the operating assembly and a transmitting wire that is at least partly wound around the operating-side pulley to transmit power to the moving assembly,
• a transmission compensating assembly including an urging member configured to urge the transmitting wire, a moving member for moving the urging member, and a driving member for driving the moving member, wherein the transmission compensating assembly at least partially removes a slack in the transmitting wire by means of the urging member;
• a sensor for detecting a rotation of the operating assembly resulting from a rotational operation of the operating assembly;
• and
• a controller configured to:
• detect the rotation of the operating side-pulley in a given direction with respect to a rotating axis of the operating assembly;
• and
• where the rotation is detected, drive the driving member to urge the urging member located between the moving assembly and the operating-side pulley against the transmitting wire for removal of the slack in the transmitting wire
• wherein the urging member is disposed between the moving assembly and the operating-side pulley.
