A proximity sensing autonomous robotic system and apparatus is provided. The robot includes one or more vision modules for viewing the environment for depth perception, object detection, object avoidance and temperature detection of objects. A proximity sensing skin is laminated on one or more parts of the robot. The proximity sensing skin includes a plurality of proximity sensors and mechanical stress sensors for collision avoidance, speed control and deceleration of motion near detected objects, and touch recognition. The proximity sensing skin may include conductive pads for contacting different materials in a composite part to inhibit galvanic corrosion. The robot includes an end effector to which different tools may be attached for performing different tasks. The end effector includes a mounting interface with connections for supplying power and hydraulic/pneumatic control of the tool. All wiring to the sensors and vision modules are routed internally within the robot.

Jointed control platform

A medical device having a force transmission mechanism that includes a chassis having a pivotal support that defines a first axis. An axle is supported by the pivotal support and is free to rotate around the first axis of rotation. The axle defines a second axis of rotation perpendicular to the first axis of rotation. A first control arm is coupled to a first end of the axle and is free to rotate around the second axis of rotation. A second control arm is coupled to an opposite second end of the axle and is free to rotate around the second axis of rotation independently of the first control arm. A distal component is coupled to an elongate tube that is coupled to the chassis. Four drive elements coupled to the control arms control motion of the distal component. In one implementation, the medical device is a teleoperated surgical instrument.
