    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: Techniques for limiting motion of a first structure include a manipulator supported by the first structure, a second structure supporting the first structure, and a processor. The processor is configured to, in response to entering a first mode, determine, relative to the first structure, a first position of a reference location on entry into the first mode, the reference location being associated with a link of the manipulator; and while in the first mode: detect a manual movement of the reference location to a second position relative to the first structure, wherein a difference between the first and second positions comprises a displacement having first and second components in respective different first and second directions; and, in response, command the second structure to move relative to the reference location in the first direction so as to reduce the first component while not changing the second component.
