Abstract: A force transmission transmits forces received by three levers to an input gimbal plate having three support points. The input gimbal play may in turn transmit the force to a wrist assembly coupled to a surgical tool. The three axes of rotation for the three levers are parallel. Two of the levers may have half-cylinder surfaces at an end of the lever to receive a support point of the input gimbal plate. Two of the levers may be supported with one degree of rotational freedom orthogonal to the axis of rotation of the fulcrum. A spring may draw the second and third levers toward one another. Two levers may have stops that bear against the support points. The force transmission may include a parallelogram linkage that includes a rocker link pivotally coupled to the first lever and having a flat surface that supports the first gimbal support point.

Abstract: A working device (1) using a parallel link mechanism includes: a parallel link mechanism (10) by which end effectors (4, 5) are supported so as to be changeable in posture; and posture-controlling actuators (11) which actuate the parallel link mechanism (10). In the parallel link mechanism (10), a distal-end-side link hub (13) is connected to a proximal-end-side link hub (12) via three or more link mechanisms (14) so as to be changeable in posture of the distal-end-side link hub (13) relative to the proximal-end-side link hub (12). The end effectors (4, 5) are mounted to the distal-end-side link hub (12), and includes one main end effector (4) which performs a main work on a workpiece (3) and one or multiple sub end effectors (5) which perform an auxiliary work on the workpiece (3).

Abstract: A control arm assembly for controlling a robot system includes a gimbal that is moveable and rotatable about three axes, and a handle assembly coupled to the gimbal. The handle assembly includes a body portion having a controller disposed therein and a first actuator disposed thereon. The first actuator is mechanically coupled to the controller via a four-bar linkage such that actuation of the first actuator causes mechanical movement of a component of the controller which is converted by the controller into an electrical signal.

Abstract: A force transmission transmits forces received by three levers to an input gimbal plate having three support points. The input gimbal play may in turn transmit the force to a wrist assembly coupled to a surgical tool. A first gimbal support point is supported by a first lever having a fulcrum with one degree of rotational freedom. Second and third gimbal support points may be supported by second and third levers having fulcrums with two degrees of rotational freedom. These fulcrums may include a first axle coupled to the lever and a second axle that supports the first axle and provides the fulcrum for the supported lever. A spring may draw the second and third levers toward one another. The force transmission may include a parallelogram linkage that includes a rocker link pivotally coupled to the first lever and having a flat surface that supports the first gimbal support point.
