Abstract
An instrument drive unit includes a hub, a motor pack, and an annular member disposed between the hub and the motor pack. The hub and motor pack each have a surface feature. The motor pack is rotatably coupled to the hub. The annular member defines an upper annular channel, and a lower annular channel. The annular member has a stop formed in each of the upper and lower annular channels. Upon the motor pack achieving a threshold amount of rotation relative to the hub, the surface feature of the motor pack abuts the stop of the lower annular channel to rotate the annular member. Upon the annular member achieving a threshold amount of rotation relative to the hub, the stop of the upper annular channel abuts the surface feature of the hub stopping further rotation of the motor pack.
