I am new to robot community but have been interested since I was a kid. I recently purchased two(2) Isobots from eBay. Only one works. Is there a mother board or robot controller that will fit inside of an Isobot? I put a Robi head on the one that works and was wanting to install a camera and a ez robot ez-bv4/2. Does anyone know if this will be possible? I saw someone on YouTube install a arduino inside an Isobot and was wondering how complicated would it be? Thank you for any available information.
