The Segway
The Segway HT (Human Transporter) first presented to the public in 2001. It is a revolutionary form of transport, which runs electricity and allows the rider to balance on a small platform between two wheels. Balance maintained by two computers, which monitor the Segway's move. As the vehicle moves off balance, the computers turn the wheels to compensate, this way restoring balance. If the rider leans forwards or backwards, the Segway moves in that direction in an attempt to steady . If the rider continues to lean, the vehicle continues to move at up to 10 mph. Once you are the move, the Segway be steered in the direction you want to go using the handlebars. are thought to be a number of advantages to the Segway for short, inner-city journeys. It's a very safe, environmentally-friendly means of transport, and a number of organisations, such as police forces and postal services, consider to be a possible alternative to cars and bicycles.
