Segway Personal Transporter

The Science Behind the Segway Personal Transporter

The Segway PT only has two wheels, yet it manages to stay upright by itself. To move forward or backward on the Segway PT, the ridersegway.jpg just leans slightly forward or backward. To turn left or right, the rider simply moves the Lean Steer frame left or right. The Segway PT is controlled by an intelligent network of sensors, mechanical assemblies, propulsion, and control systems. The second you step on, five micro-machined gyroscopic sensors and two accelerometers sense the changing terrain and your body position at 100 times per second.

 

Simply put, the Coriolis effect is the apparent turning of a moving object in relation to another rotating object. For example, an airplane trying to travel in a straight line can appear to turn because the Earth is rotating underneath it. The brains and brawn are made up of two identical and redundant sets of microprocessor-based electronic controller circuit boards, batteries and motor windings that operate together and share the load of driving the wheels. The Segway PT has a number of additional onboard microprocessors. The microprocessors run an advanced piece of software that controls the Segway PT. This program monitors all of the stability information coming from the gyroscopic sensors and adjusts the speed of the electric motors in response to this information.
