Step 17How does it work? - the motor and the switch part 2
Here you can see what happen when electricity flow through the circuit. Check the second picture.
So you can see that one battery will power BOTH motor when the robot run around your house.
The second battery is only to reverse the beetlerobot when it get stuck. SO this battery will last longer!!
Swap the battery to prolong your battery life and also the robot life.
If the opposite motor does not spin, this mean that you might have a weak battery or simply that the third connection is not working right.
