5 Degree of Freedom Arm
thingiverse
This educational 5 DoF Arm project is currently in progress as version 0.3, dated November 1st. The arm's motors are sourced from Pololu (http://www.pololu.com/catalog/product/180), but a more powerful version may be considered for future upgrades. One motor struggles to support the entire weight of the arm; thus, it drops to its local equilibrium point when power is cut. SparkFun switches (https://www.sparkfun.com/products/10545) are used, with upward and downward pushes controlling motor direction. A fun inclusion is a missile switch.
