I cut off Middle plastic part and replaced it with wood, then I added 4x1.5V battery pack in the middle of it.

Step 3: Wiring Scheme

Picture of Wiring Scheme
Connect one motor to the OUT1 and OUT2 pins of L298N, connect second to the OUT3 and OUT4 pins.
Connect positive wire of batteries to +12V pin and negative to the GND of L298N, then connect same GND to GND of arduino.
Pins of HC-05 are conected to arduino like this: GND to GND; VCC to 5V; RX to TX and TX to RX.
Pins of arduino 8,9,10,11 are connected to IN1,IN2,IN3,IN4 of L298N.
