So we’ve got our parts and our motor controller so we are now ready to make this robot move forward, backwards and turn. I’m assuming you’ve put the wheels on the motors, mounted them to your design, used a gearbox if necessary and you do have a motor controller. Plus you also have the 9 volt battery and clip for Arduino.

In this part we will need:

  • Arduino Duemilanove ATmega328
  • 4 x NPN general transistors (e.g. PN100, PN2222)
  • 4 x 6.2K Ohm resistors (10K will do fine too)
  • Breadboard
  • Some wire

I’ve decided to make the next project that just about every person exploring electronics does… the making of a small robot. In my case, I’ll be using the Arduino to control the robot which will just be a robot that can avoid walls that  I might build more functionality in the future.

The first part of the project is to acquire the necessary parts such as motors, gears, wheels, infrared sensors, etc. Luckily for me, I actually had a robot that I was building up before; it’s the Cycbot from RealRobots (for anyone who might remember it). I got around to issue 6 or 7 and eventually gave up on it. I do however have the motors, gears, wheels and the motor controller, so it’s all actually working, it just goes forward for now.
