The force information calculating part is configured to obtain an information on the force applied to the cover from data measured by the force sensor, when the force is applied to an arbitrary position of the cover.

Two-degree-of-freedom rope-driven finger force feedback device

The present invention provides a two-degree-of-freedom rope-driven finger force feedback device. The two-degree-of-freedom rope-driven finger force feedback device includes a hand support mechanism, a thumb movement mechanism, an index finger movement mechanism, and a handle mechanism. The hand support mechanism includes a motor, a motor shaft sleeve, a sliding rail, and an inertial measurement unit (IMU) sensor. The thumb movement mechanism includes a long rotary disc, a torque sensor, an angle sensor, a thumb sleeve, a pressure sensor, two links, a thumb brace, and a thumb fixing ring. The handle mechanism includes a cylindrical handle, a pressure sensor, a flexible fixing band, and a slider. Torque is driven between the rotary disc and the motor by using a rope. The handle mechanism is movable forward and backward and is capable of automatic restoration. By means of the present invention, the problems of the high costs of a conventional finger force feedback device and the unadjustable characteristic of the conventional finger force feedback device are overcome. The device can be tightly worn and has a self-adaptive degree of freedom. Rope driving can ensure a gentle, smooth, and real feedback force. By means of the mounted sensors, information such as a hand posture, a rotation angle and a grip force of a thumb and an index finger, and a contact force of a middle finger can be transmitted in real time.

Mechanical hand, useful in robotics

A mechanical hand mimics a human hand having similar degrees of freedom and sensory abilities while appearing visually similar to human hand. The mechanical hand comprises a mechanical hand skeleton and resilient elastomer (e.g., silicone) skin that fully encloses the mechanical hand skeleton. The mechanical hand skeleton may advantageously be molded directly into the resilient elastomer (e.g., silicone) skin such that the hand appears, moves, and feels very similar to a real human hand. The mechanical hand may have applications in robotics, for example as an end-of-arm tool or end effector, or may have other applications. Robotic applications may include prosthetics applications.

Humanoid Hugging Assembly

SYSTEM AND METHOD OF ACTIVATING MANUAL MANIPULATION USING LINKAGE INTERACTION SENSING

Robotic medical systems capable of manual manipulation are described. A robotic medical system can include a robotic arm and a sensor architecture. The sensor architecture can include one or more non-joint based sensors that are positioned to detect a first force exerted on the robotic arm. The robotic medical system can be configured to determine whether sensor data received from the sensor architecture meets first criteria. For example, the first criteria can be met in accordance with a determination that the first force exceeds a first threshold force. The robotic medical system can be configured to, in accordance with a determination that the first criteria are met, transition the robotic arm from a position control mode to a manual manipulation mode.
