摘要：
Systems and methods for operating an end effector include a first jaw, a second jaw, a first actuation mechanism configured to actuate the first jaw and the second jaw toward each other with a first force, and a second actuation mechanism configured to actuate the first jaw and the second jaw toward each other with a second force greater than the first force. The second actuation mechanism is different from the first actuation mechanism. In some embodiments, the first actuation mechanism includes a first pull cable configured to increase an angle between the first jaw and the second jaw and a second pull cable configured to decrease the angle between the first jaw and the second jaw. In some embodiments, the second actuation mechanism includes a lead screw.
