So you would like to build your own Darth Vader robot with app control? You can easily use ez-robot technology to complete this project. Darth Jader can be built using a modified JD Humanoid robot with plastic brackets painted in black. The head is 3D printable.
JD is already a WiFi enabled humanoid robot with LEDs, heavy duty servos, 16 degrees of freedom, so it can dance, walk, and learn new skills.[where to find more info]
