GoGo ballet is a simplified version of the GoGo with an addition of RF wireless communication. It was first designed for Roballet, a research project where children attach various sensors to their body allowing them to control the environment (light, sound, video projection) using their movements. GoGo ballet was designed as a fallback plan, as, for a short time, we were experiencing problems with another wireless board we wanted to use.

You will need a base station to communicate with GoGo Ballet. Information about this base station will be available soon.
