The Driving Mechanism works the same as the Steering Mechanism. When a command is received to go forwards the SCRX2BC creates a voltage at pin 11 which turns on Q2. This then turns on Q5 and Q8 and current flows from the batteries through Q5, then through the driving motor, and then through Q8 to ground. Similarly to go backwards the voltage is created at pin 10, and Q3, Q6, and Q7 are turned on. The small gear on the Motor drives the Middle Gear, which drives the gear on the rear wheels axle, making the wheels move. Note that the gears on the Motor.
