The iBot motorized wheelchair was first unveiled back in 2001, but it still looks remarkably futuristic today. The device was created by Segway inventor Dean Kamen, and could climb stairs, raise users from sitting level to eye-height, and travel at a steady walking pace in this "standing" configuration. However, with prices starting at $25,000, the device was too expensive for the mainstream market and was eventually discontinued in 2009. Now, it's making a comeback, with help from Toyota.
