Following on from Part 3, our motor controller has been successfully built and tested, now it’s time to release the parts used, where to place them, etc so you can build your own. I’ve actually taken consideration to what I said in Part 3 and have re-designed the Motor Controller to have the components and lines to be spaced out a bit more however I’ve changed the lines back to 0.254mm wide. You have the option of both v1.0 or v1.1 boards, I recommend v1.1 even though it is a little bigger.
Following on from Part 1, we’ve done our design and now it’s to put our prototype to the test, this will post won’t be as long as the design because all we need to do is test.
This is how our circuit looks to power 1 motor in 1 direction only.
We know how to control our 2 motors in both directions and we also know how to use our Phototransistors to detect if an object is close, now we put both of these together to form our robot. In this part we focus more on producing the code as we’ve already put our robot together as below.
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.
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.
