This robotic hand was constructed by Gary Perceval. It is an example of what 3D printing can be used to produce using electronics and computing application.
This is a life size robotic hand 3D printed and constructed using servo motors controlled by an Arduino microcontroller programmed with C++ code. The code allows fingers and thumb to be controlled by the switch panel and several routines are coded to give familiar hand signals at the press of a “binary” code button.
