Build your own Segway

This article tells how to build your own self-balancing scooter like a Segway™.

Although the Segway has several exotic components, this one is built from common low-tech parts like wheelchair motors and RC car batteries. The parts, even at small quantity retail prices, cost less than half of a genuine Segway. It also doesn’t need complex or high-performance software. The first version was written in Python and used serial ports to talk to the gyroscope and motor controller. The current software, now in C running in an onboard 8-bit microcontroller, is only 500 lines of code.
