The IBOT wheelchair allowed it’s user to speak to people at eye level, raise them higher to reach things, and easily go up and down curbs and stairs. Lots of clever computers, a bit of nifty software and a lot of gyroscopes (motion sensors) allowed the chair to constantly balance itself no matter where its user was leaning or traveling. The iBot was released in 2003 but was ditched in 2009 because it was too expensive to manufacture and insurance would cover only a quarter of the $22k bill.
