Would there be friction if we went for a spin or straight setup. The left side and the right side go in opposite directions to rotate us. They go in the same direction to move us foward and backward. Obviously, this would kill are ability to do gradual turns because as you said this would cause one side of the robot to drag putting strain on the motors. Can you give me some other steering alternatives or different gearbox setups? Thank you very much.
