I just wanted to share a little project we just finished. The idea was to have a moving lightsource at home
We upgraded the 3pi robot with some RGB LEDs a bluetooth module and a front sonar.
We can control the robots color and brightness manually via Android app or via Androids voice commands. The motors can be controlled naturally thanks to the gyroscope. I think a short demo video is the best way to visualize our development. Also, the source code for the robot and the androip app is available at github. The links are:
