Abstract: A lock and a method and a system for controlling the lock are provided. The lock includes an operation part, an action part, and a bolt. The action part is configured to drive the bolt to move. The operation part and the action part are connected to each other via a transmission connection. The transmission connection is blockable.

Abstract: An instrument drive and a surgical robot are provided. The instrument drive includes a motor, a reducer, a reducer output stage, and a driving disc assembly. The motor is configured to drive a gear of the reducer to rotate, and the reducer is configured to drive the driving disc assembly to rotate. The instrument drive further includes an output stage magnetic ring and an output stage encoder. The output stage magnetic ring is coaxially arranged with the reducer output stage, and is configured to rotate synchronously with the reducer output stage. The output stage encoder is spaced apart from the reducer output stage in a radial direction of the reducer output stage and configured to detect the rotation of the output stage magnetic ring.

Abstract: The present disclosure provides a lock and a method and a system for controlling the lock. The lock may include an operation part, an action part, and a bolt. The action part may be configured to drive the bolt to move. The operation part and the action part may be connected to each other via a transmission connection. The transmission connection may be blockable.

Abstract: A stop device includes a first shift lever including a first shifting part configured to rotate around a rotation axis to form a first motion trajectory, and a second shift lever including a second shifting part partially within the first motion trajectory. The first shifting part drives the second shifting part to rotate around the axis of the rotating shaft to form a second motion trajectory. The stop device further includes a stopping boss located on a periphery of the first motion trajectory and partially within the second motion trajectory. The second shift lever rotates to drive the second shifting part to contact a first side of the stopping boss when rotating in a first direction and to contact a second side of the stopping boss facing away from the first boss when rotating in a second direction opposite to the first direction.

Abstract: A quick gimbal connector comprises: a first cylinder comprising a sliding slot on an inner wall of a first end of the first cylinder, at least one entrance provided at an end portion of the sliding slot, and a first boss provided on the first cylinder; a second cylinder coaxially and rotatably connected with the first cylinder; a connector; at least one rib provided on the connector; and a connecting plate fixedly connected with the second cylinder and being provided with a second boss. The at least one rib is configured to fit with the at least one entrance and can enter into and exit from the sliding slot via the at least one entrance when the first boss abuts against the second boss, such that the first cylinder and the connector can be locked or separated.
