What distinguishes a RoseRolls from a Sphero, is our extension board that comes in addition to Sphero's regular board. Obviously you will need one of them before you can start the process. Feel free to contact us at RoseRolls2013@gmail.com to get one.
You will also need a new shell. We used 7cm (2,76 inches) transparent plastic christmas balls that can be purchased in various craft stores for very cheap, and got rid of the hook.
