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 active compliant parallel device includes a movable body; a base body; and a plurality of linking members. The plurality of linking members are coupled to the movable body and the base body by a plurality of joints and include at least one compliant linking member, having a compliant element, and at least one actuating linking member, having an actuating element. The device may further include at least one damping linking member having a damping element and/or at least one passive linking member. The actuating, compliant, passive, and/or damping linking members are arranged in a parallel arrangement or structure such that each linking member makes a connection, using a connection element, such as a joint, with the base body and the movable body. The potential configurations of the device allow for movement and positioning of one or more unrestricted and externally loaded elements in space.

An extended-reach assist device for an assembly task includes a base mechanism and a compliant end-effector. The articulated base mechanism provides one or more passive degrees of freedom. The end-effector is connected to the base mechanism, and has one or more active or passive degrees of freedom collectively configured to react to contact forces with the assist device when completing the dexterous assembly task. A weight of the end-effector is supported by the base mechanism. The end-effector may be optionally configured as a passive device configured to produce a remote center of compliance or as a robot mechanism. A mechanism may actively or passively augment a force applied by the operator. A sensor may detect a signature indicative of successful task completion, e.g., an acoustic, visual, or audio sensor.

A platform for a parallel robot, for acting on an object, including: at least two frames comprising at least two pairs of swivels; at least two bridges that are connected to each of the frames respectively by four hinges which are substantially parallel to an axial direction (V); and a base to be connected to an effector, which is suitable for acting on the object.

The base is connected to each bridge respectively by at least one hinge which is oriented along a connection axis which is substantially parallel to the axial direction.
