Ball follower using vision processing

Video processing has always been challenging to robot builders as the coding is complex and people who don’t have the knowledge in MATLAB can’t do much, but in this tutorial we will be learning how to program a robot to follow a yellow coloured ball, using image processing, which works much faster than MATLAB programming and is much easier.

• For this I used VIZ bot kit from TRI, or you can make your our board which consist of a driver board or(L293D)that takes inputs from pin 5 and pin 2 of the parallel port.

• You would also need a WEB cam for capturing the video.

• Download and install Robo Realm.

Step 1 Set up roborealm

Once you have set the camera, you will be able to see the video, now place an object in front of the screen.
