Free to a FRC team.
My neighbor has literally worn the seat off her 1st gen iBot chair. Rather then trash it, she would love a team to take it and do with it what they want. Deconstruct it/rebuild it, whatever your team wants to do, as a learning opportunity. Comes with additional wheels and batteries. NO OWNERS MANUAL.
My engineering college kid did get it running but just doesn’t have the time (and I want my basement back).
Very heavy -requires muscles and a truck for transport. Located in Central Massachusetts.
