    Two-wheeled-racer
    (2013) Dreher, Marcel
    The following document describes the process, problems and solutions of the project "Two-Wheeled-Racer". The project focuses on constructing the robot and providing the core communication principles in addition with basic balancing control. The single-board computer Odroid-X2+ is used as a brain for the Racer to process the data received from an accelerometer and a gyroscope and solve the inclination angle problem. To reduce the noise of the sensors the data are filtered and combined with the help of a complementary filter. A PID control algorithm is running on the Odroid-X2+ to react on the inclination angle calculated from the sensor data and to prevent the robot from falling over. Two 30:1 gear motors controlled by a MD25 H bridge dual motor drive are used as actuators. The data are transferred among the hardware components with the help of the I2C protocol.
