The Segway hit the market in 2002 with a splash. You might have seen one before. It is a two-wheeled electric power transporter where the rider stands on a platform and pushes on a tall handlebar and the vehicle moves them where they need to go. The Segway can motor as fast as 12.5 miles an hour and balances itself, so the driver doesn't need to worry. There are sensors inside to make sure it is always heading in the right direction.
