This is Roboball, it was designed , built and tested within about 6 weeks. most components are FIRST legal though I had to swap out a few things in order to fit under my weight limit of about 20 Kg ( 44 lbs). First ran about this time last year. It is capable of about 20 mph and will run for about an hour before the motors over heat or the battery for the IFI EDU controller dies. The ball material is a 50 inch diameter big-ins ball similar to the ones that have been used in a few FIRST competitions in the past. the little green wheels are just there in case the pendulum arm impacts the ground while traveling over bumpy terrain. It is inflatable and yes can travel across water.
