About the Segway i2
Segway Human Transporter can self-balance because of a technology called Dynamic Stabilization. Dynamic Stabilization works much the same way your own sense of balance does. Where you have an inner ear, eyes, muscles, and a brain to keep you balanced, the Segway HT has solid-state gyroscopes, tilt sensors, high-speed microprocessors, and powerful electric motors performing to keep it balanced. Working in concert, these extensively tested, redundant systems sense your center of gravity, instantaneoulsy assess the informantion, and make minute adjustments, one hundred times a second. Segway HT balances whether you're traveling at 10 mph, carrying a heavy load, slowly maneuvering in tight spaces, or standing perfectly still.
