Finally completed my self balancing two inline wheeled vehicle project which really began about seven years ago and culminated in this vehicle using 730gram gyroscope rotor, dc 395 gimbal control motor and VNH5019 motor driver. It uses RC gear to control vehicle drive motor and steering and an Arduino Uno to control the gimbal balancing control using a single non-contact potentiometer to determine vehicle angle (gimbal angle).
