A soft actuator includes a power input shaft, and multiple electromagnetic clutches are coaxially installed in series on the power input shaft. A bending elastic part is arranged between the thrust plate of each electromagnetic clutch and the gear frame of the electromagnetic clutch. The bending elastic part is installed on the sleeve of the gear frame and in contact with the baffle of the gear frame. The bending elastic part is connected with the clutch output gear of the electromagnetic clutch through the gear frame. The gear frame is fixedly connected with the clutch output gear and rotates coaxially.

A force transmission system as part of a surgical system which may be configured to be a minimally invasive and/or computer assisted surgical system. Operation of the system may be controlled by transmission of a force from a first section to a second section of the system. The first section and the second section may be separated by a partition or a barrier. The first section may be a non-sterile section and the second section may be a sterile section of the surgical system.

Disclosed herein are various medical devices and related systems, including robotic and/or in vivo medical devices. Also disclosed are various robotic surgical devices for in vivo medical procedures. Included herein, for example, is a robotic surgical system having a support beam positionable through an incision, and a robotic device having a device body, first and second rotating shoulder components coupled to the device body, and first and second robotic arms coupled to the first and second shoulder components, respectively.

A multi-articulated manipulator composed of more than one hollow outer shell, joints to connect the outer shells to each other, a grasping member fastened for rotating movement with respect to the proximal outer shell, a claw transmission shaft to actuate the grasping member to rotate and an outer shell power transmission shaft to actuate the outer shells in to rotate independently from each other. The claw transmission shaft and the outer shell power transmission shaft respectively are composed of universal joints capable of rotating force and transmitting torque.

A control circuit of a piezoelectric driving device includes: a signal generation unit that inputs a state inspection signal to a plurality of piezoelectric elements connected to each other in parallel; and a state detection unit that detects a state of the plurality of piezoelectric elements based on a state detection signal generated from the plurality of piezoelectric elements in accordance with the state inspection signal.

Described is a system for finding open space for robot exploration. During operation, the system designates a straight forward direction as a default direction. It is determined if a filtered 3D point cloud has a sufficient number of cloud points. If not, the system determines if an obstacle is too close in a previous time. If so, a backward direction is set as a target direction and if not, the straight forward direction is set as the target direction. Alternatively, if there are a sufficient number of points, then calculate a distance of each point to a sensor center and determine if a number of times that the distance is smaller than a distance threshold is greater than a fixed number. The system either sets the backward direction as the target direction or estimates an openness of each candidate direction until a candidate direction is set as the target direction.
