The iBOT was a powered wheelchair that could “walk” up and down stairs, it allowed the user to rise from a sitting level to approximately 6′ tall, and the iBot could climb and descend curbs. It climbed stairs by rotating its two sets of powered wheels about each other. Unfortunately, due to its prohibitive price, the iBot did not sell very well and manufacturing was discontinued by 2009.
