If your MiPosaur is not moving correctly, this guide will allow you to fix the most likely cause. Before you begin, turn MiPosaur off and spin both wheels. If one makes an abnormal whir, this guide can help correct the issue. You can also check by jiggling both wheels gently. If one does not stay in place correctly, that wheel is the one with the issue.
