NXT Robotic Arm

This app lets you control an Lego Mindstorms Robotic Arm in several modes:
Button Mode - direct control to your three motors
Sensor Mode - the arm follows the movement of your phone
Drawing Mode - predefined movements to draw numbers from 0 to 9 (but more to go)

Although it is designed to control an Robotic Arm you can use it for any Lego Mindstorms creation of yours because you have direct access to all the three motors and individual adjust their power.
