How it Works:
The key to how the Beetlebot works is in the switches. They are not simple on/off
switches - they are “Single Pole / Double Throw” switches, which means they make a
connection to one wire or the other wire - there’s no “in between”.
The motors are connected from between the two battery packs to a switch. Depending
on the switch, the other wire to the motor is connected to the “+” side of one pack, or
the “-” side of the other pack. Since motors change direction when you reverse the
power connections, this behavior lets the switch and two battery packs change the
direction of the robot.
The power switch has several wires because it disconnects both battery packs. If you
disconnect only one wire, your BeetleBot will stop running forwards but will still run
backwards.
