A vacuum gripper for gripping an object surface using vacuum suction is configured to be portable or operated by a hoist. Battery conservation measures are included to provide a long term vacuum generation capability, together with manually rechargeable mechanism. A manually-operated vacuum pump is also integrated to the vacuum gripper as a safeguard for the battery-operated vacuum pump failure. The vacuum gripper includes an elastic deformable vacuum seal for gripping objects with irregular surfaces, together with press rods or pin array configured to assist the vacuum seal in filling any gaps between the vacuum seal and the object surface.

A vehicle repair hand tool has a handle, a connecting rod, a connecting unit and a working unit. The connecting rod is connected with the handle. The connecting unit is connected with the connecting rod and has an engagement hole. The working unit is connected with the connector and has a base, an engagement unit and a working body. The base has a sliding recess and a recess opening formed in a bottom of the sliding recess. The engagement unit is mounted in the sliding recess and has a sliding block slidably mounted in the sliding recess. The engagement unit further has an engagement ball mounted in the recess opening, sheltered by the sliding block, and selectively engaged in the engagement hole. The working body is mounted on the base.

A device for repositioning bone fracture fragments is disclosed. The device has a carrier assembly and a first arm assembly attached to the carrier assembly, the first arm assembly configured to hold a first bone fracture fragment. The device also has a second arm assembly attached to the carrier assembly, the second arm assembly configured to hold a second bone fracture fragment. The device further has an actuator assembly configured to adjust the second arm assembly, and an operating assembly configured to control an adjustment of the second arm assembly via the actuator assembly. The operating assembly is a manually operatable operating assembly.

The invention relates to a robot comprising a tool (8), a first chain of elements having a proximal end element (6) and a distal end element (7) to which the tool is connected, at least one control member (9) of the robot connected to one of the elements of the first chain of elements other than the distal end element, control means (13, 14, 15) for at least one part of the first element chain and the control member in order to associate, with a movement of the control member relative to the proximal end element along at least one degree of freedom of the control member, a more complex movement of the distal end element relative to the proximal end element along at least one of the degrees of freedom of the distal end element.

The present invention provides a handheld robot for orthopedic surgery and a control method thereof. The handheld robot of the present invention includes a main body, a grip, a kinematic mechanism, a tool connector, a tool, a force sensor and a positioning unit. The handheld robot of the present invention combines the position/orientation information of the tool acquired by the positioning unit with the force/torque information acquired by the force sensor, and utilizes the combined information to adjust the position of the tool so as to keep the tool within the range/path of a predetermined operation plan. In this way, the precision of the orthopedic surgery can be enhanced, and the error occurred during the surgery can be minimized.

An apparatus comprises a main arm having links extending from a ground end to an effector end and allowing movement of the effector end from a first position to a second position, the links including at least a base link adapted to be pivotally connected to a base, and a spacing link pivotally mounted to a free end of the base link and extending to the effector end. A first 4-bar parallelogram has pivot joints at its corners and including the base link of the main arm. A second 4-bar parallelogram has pivot joints at its corners and including the spacing link of the main arm and an effector link at the effector end adapted to support an object. A serial interconnection is between the first 4-bar parallelogram and the second 4-bar parallelogram constraining the effector link to maintaining a constant orientation in at least two rotational degrees of freedom relative to the base.
