dIMU Days: Lejos!

    Hello everybody,

    I’m working on a robot that has to be stable on a ball, like the new Star Wars BB8 robot.
    I’m using an EV3 Lego Mindstorm with LEJOS interface and I’m programing with JAVA.

    My problem is about the stability. When I hold the ball and when I roll it in one way ( slowly) the robot go back to his initial position. However if I leave the robot alone, the ball rolls alone too fast and the robot can’t stay stable and fall always.

    The robot has 3 omniwheels placed 120° from each other, the ball is a gym ball which is bigger than the robot. I’m using DexterIMU gyroscope and DexterIMU accelerometer.

    Do you have any tips to resolve this problem ?

    Many thanks !

    Christophe
