Adaptor for food-safe, bin-compatible, washable, tool-changer utensils
Robots, including robot arms, can interface with other modules to affect the world surrounding the robot. However, designing modules from scratch when human analogues exist is not efficient. In an embodiment, a mechanical tool, converted from human use, to be used by robots includes a monolithic adaptor having two interface components. The two interface components include a first interface component cabal be of mating with an actuated mechanism on the robot side, the second interface capable of clamping to an existing utensil. In such a way, utensils that are intended for humans can be adapted for robots and robotic arms.
