1. A force transmission system for a robotically controlled medical device, comprising:
a pushing actuator configured to be pushed by a robotic instrument controller;
a wire having:
a first end attached to an end of the pushing actuator to be pushed distally by the pushing actuator or attached to a location that moves with movement of the pushing actuator; and
a second end attached to a distal location of the medical device; and
a reverse motion device interfaced with the wire between the first end and the second end, the reverse motion device being configured to cause a proximal pulling action on the second end in response to pushing of the first end distally by the pushing actuator or other actuation by the pushing actuator, wherein the reverse motion device is configured to maintain a point of contact with the wire in the same spatial location to prevent wire motion due to actuation.
