My own version BB-8, the new droid from Star Wars: The Force Awakens.
Check-out the video for a demo and overview of the assembly process.
It's powered by an Arduino board and remote controlled via RF. This droid self-balance on two wheels, play sounds, and has several programmable LEDs.
Advantages of this version:
- Half-size, meaning shorter printing time : 50 hours versus 300+ hours for a full-size version.
- 3D details on the shell meaning less painting required.
- Can easily move around on wheels, keeping its head on top.
- Robotic platform is the instabot v3 available from Sainsmart.
