The Segway PT
The Segway PT (abbreviation for Personal Transporter) is a two-wheeled, self-balancing, battery-powered electric vehicle invented in the United States in 2001. It is produced by Segway Inc. of New Hampshire, USA.
The Segway PT is the first auto-balanced transportation device. Computers and motors in the base of the device keep the Segway PT upright when powered on with balancing enabled. A user commands the Segway to go forward by shifting their weight forward on the platform, and backward by shifting their weight backward. The Segway detects, as it balances, the change in its center of mass, and first establishes and then maintains a corresponding speed, forward or backward. Gyroscopic sensors and fluid-based leveling sensors detect the weight shift. To turn, the user presses the handlebar to the left or the right. The PTs are driven by electric motors and can go up to 12.5 miles per hour that can be controlled and programed electronically.
Segway Inc. has over 100 concessionaries and distributors all around the world. There is official tours given in more than 37 countries and around 134 locations.
