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 Leave a reply Click here to cancel the replyYou must be logged in to post a comment.
