Programmable Electric Vehicle(Arduino+TAMIYA)

combine TAMIYA BULLDOZER and arduino, you can build a programable electric vehicle.

Step 1: Building Up TAMIYA BULLDOZER KIT

Step 2: DC Motor H-Bridge Driver Board

Step 3: Connecting and Software

Software:

The motor is design for 3V power.

This project using one 9V power source.

I use arduino's PWM to power the motor, the PWM value is 80.

Step 4: Insufficient Torque and Change Gear Box

gear box ratio

original: 1:203.7

new gear ratio : 1:441

Step 5: Add Limit Switch for Counting Step

Step 6:

Step 7: Play

press keypad for which motion you want

one motion one enter

finally press "go"
