The Segway Personal Transporter is the brainchild of Dean Kamen. Introduced in 2001, this personal mobility device was touted as the next great transportation revolution. This 2002 model "i" weighs 83 pounds, has a speed of 12.5 mph, and a range of 8-12 miles. The Segway uses sophisticated electronic gyroscopic sensors and microprocessors to maintain balance and respond to operator's commands.
