(assuming that the center of gravity of the robot is close
to the two wheels). The circle in the front of the robot is
a skid of some soft (this is any smooth piece of plastic,
such as a ping-pong ball or a bottle cap). Because this
skid is smooth, it doesn’t mind making the large sideways
motion, and the robot will turn easily.
We use two step motor and one ping-pong ball
