Photos: Segway's rolling technology

Segway's XT Human Transporter, billed as suitable for rough terrain, features wide tires designed to increase stability on uneven ground, and low tire pressure meant to minimize the impact of bumps. It is priced at $4,995.

Segway's Human Transporter can be equipped to carry small cargo, including items as large as a set of golf clubs. Priced at $5,495, this model features tires designed for enhanced traction.

One of Segway's prototype vehicles, the Concept Centaur, uses what the company calls "dynamic stabilization" technology, which also helps operate the Human Transporter. This model, shown at the North American International Auto Show in Detroit, is equipped with Michelin "Tweel" tires.

The Robosapien robot toy is produced by Hong Kong-based Wow Wee, which has struck a deal to license Segway's technology and know-how.
