Project description

Code

Androidcode

java

This is the core of the Android application. It uses a virtual Joystick library (zerokol's JoystickView).

Nano Code

Inner gears.

The gear in the middle is the one driving the four other gears of the left side (same thing goes on the right side). to connect it to the motor, I had to cut a bit of the piece and glue it to the motor shaft. Then, you connect the legs to the gears, asynchronously (each on a gear hole) and tadam: silly walk.
