Counterbalance mechanism for robotic assist device
An electromechanical system operates in part through physical interaction with an operator, and includes a multi-axis robot, a controller, and a counterbalance mechanism connected to the robot. The counterbalance mechanism includes a base structure connected to a set of linkages, a pneumatic cylinder, a spring-loaded cam assembly, and an optional constant force spring. The linkages form a four-bar parallelogram assembly connectable to a load. The cylinder and cam assembly, and optional constant force spring, each impart respective vertical forces to the parallelogram assembly. The forces combine to provide gravity compensation and self-centering functions or behaviors to the load, enabling the load to move with a vertical degree of freedom when manually acted upon by the operator, and to return the load to a nominal center position.
SMART STICK ASSEMBLY
The present invention provides a smart stick assembly comprising a rod comprising a plurality of telescopic sections, wherein the rod having a proximal end and an opposing distal end. An illumination portion, disposed at the distal end of the rod, configured to illuminate. A camera, disposed at the distal end of the rod, configured to capture an image, or a video, or both. A sensor coupled to the camera to stabilize the camera during motion. The camera is configured to transmit the captured image and video to a remote communication device through the wireless transceiver. Further, detachable end effector coupled to the distal end of the rod and configured to perform an action.
WORKING METHOD AND ROBOT SYSTEM
