Left is a motor that knocks a little, the right works fine. The support team will take care of it, so don't worry. A wide range of powerful entry-level features. The Android app is AMAZING with the ability to program and save commands. I'm going to set up automatic obstacle courses for this guy. Photos of this and similar models show the second orange connector on the "top" of the engine block which was intended to be another connector for the engine. This robot has a hole where this connector should be, indicating it doesn't have an additional motor.
