A cleaning robot for underwater includes a main body including a magnetic speed detection mechanism and a magnetic collision buffer mechanism. The magnetic speed detection mechanism includes two speed detection wheel mechanisms mounted on the main body. The speed detection wheel mechanism includes a wheel bracket, an induction wheel rotationally disposed inside the wheel bracket, a magnet embedded on one side of the induction wheel, and a magnetic force sensor disposed inside the wheel bracket and located on one side of the magnet.

In a sensing device and a robot manipulator having the sensing device, the sensing device includes a cover, a force sensor and a force information calculating part. The cover has a predetermined shape and is configured to cover a body. The force sensor is disposed at a position between the body and the cover, and is configured to measure a force and a torque applied via the cover at the position. 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.

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.

A touch sensation sensor is mounted to a hand part of a robot and includes: an obtaining means, obtaining at least one of visual sensation information, which is target object information relating to a target object operated by using the hand part, and touch sensation information, which is the target object information at a time when the target object operated by using the hand part is gripped; and a control device, changing a sensitivity mode of the touch sensation sensor in accordance with the target object information that is obtained.

A robot operating device includes a camera that is attached to a distal end of a robot arm or a position adjacent to the distal end and that acquires an image; a display which displays the image acquired by the camera; an operation-accepting unit which accepts an operation that is performed by an operator on the image displayed on the display unit; and a controller which moves the robot arm based on the operation accepted by the operation-accepting unit.

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.

A humanoid hugging assembly includes a humanoid animatronic that has a torso, a pair of arms and a pair of hands each is disposed on a respective one of the arms. The arms are positionable in a resting position having the arms extending downwardly along the torso and having a palm of each of the hands facing the torso. Each of the arms is positionable in a hugging position has each of the arms is crossed in front of the torso wherein the pair of arms is configured to embrace the user. A motion sensor is integrated into the humanoid animatronic to sense motion of the user approaching the humanoid animatronic. A motion unit is integrated into the humanoid animatronic and the motion unit actuates each of the arms into the hugging position when a predetermined duration of time has passed when motion sensor senses motion.

A gripping system for an autonomous guided vehicle (AGV) and such AGV are disclosed herein. The gripping system for automated gripping and pulling/pushing a cart comprises a unique gripping end effector ensuring controlled steering of the cart while allowing rolling of the cart relative to the body of the AGV. The end effector comprises means for indication of state of connection between the cart and the gripping system, ensuring a reliable, safe and efficient cart gripping and pulling operation.

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.
