Motivation

The idea comes from the movie IRON MAN. The goal of robotic hands is to develop prosthetic devices for imitating gestures of human hands, which cost under 50 dollars and are easily made from home. Therefore, I chose 3D printing to make the hands part rather than aluminum tubes, and in order to cost down the spending on controllers, I use micro-controllers like PIC18 and Arduino rather than single-board computers such as Raspberry Pi.
