Robstep

Robstep (Chinese: 易步; pinyin: Yì Bù; lit. 'Easy Step') is a line of two-wheeled, self-balancing, battery-powered electric vehicles invented by Dongguan Robstep Robot Co., Ltd. of Guangdong, Dongguan, China. The name "Robstep" is a portmanteau of the words "robot" and "step", meaning robotic steps. The devices have been compared to Segways.

Computers and motors inside of the device keep the Robstep upright when powered on with balancing enabled. A user commands the Robstep to go forward by shifting their weight forward on the platform, and backward by shifting their weight backward. The Robstep 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. Robsteps are driven by electric motors and can reach a speed of 9.3 miles per hour (15 km/h).
