About this 3D model

A robotic arm with 2 degrees of freedom (DOF) controlled by 2 servos and an arduino. Fishing line (or extruded plastic threads) acts as tendons and a spring at each joint allow the arm to curve evenly. This project is a stepping stone to a larger project, so it is not meant to do anything useful yet, but be used as a part of whatever you can come up with.
