Segway

The Segway Human Transport is a self-balancing motorized scooter invented by Dean Kamen. The scooter is designed to be used in pedestrian areas.

The Segway HT has electric motors powered by batteries which can be charged from house current. It balances with the help of internal computers and gyroscopic sensors. (The gyroscopes do not affect the balance; they are merely used as sensors.) The motors turn the wheels forwards or backwards as needed for balance or propulsion. The rider accelerates or decelerates (or goes backwards) by leaning forward or backwards in the direction she wishes to travel. Steering is controlled by a twist grip on the right handlebar.

The Segway HT has been known by the names Ginger and IT in the past. There were various reports of a revolutionary invention, but no details were available until its unveiling on December 3, 2001. The name Segway is a play on "segue" (a transition).
