Robotic hand, method for making the same, and robot having the same

摘要

A robotic hand includes an interior casing, a cladding layer wrapped around an end of the interior casing, a plurality of photoelectric sensors, and a controller. The photoelectric sensors are located at different locations on an exterior surface of the interior casing, and are wrapped by the cladding layer. The photoelectric sensors can sense light signals striking different locations on the exterior surface of the interior casing, and convert the sensed optical signals into electrical signals. The controller can obtain the generated electrical signals, determine a pressure value applied according to the obtained electric signals, and generate a control signal according to the determined pressure value causing the robot to generate feedback.
