Development of the low cost 3D printed robotic hand controlled by 8 bits microcontroller

Prosthetics hand robot is the artificial hand that resembles the actual human's hand. This artificial hand is placed onto the amputees hand that will allow them to do the basic hand movement and to make their daily life easier. In order to perform the basic hand movement, degree of freedoms (DO...
