Samuel Matos’ self balancing Raspberry Pi Robot, RS4 uses image processing to follow a black line on the floor:
The robot has a new feature, it can follow a black line painted on the floor.
I’ve created a new sign with a line, when the robot reads this sign it will begin the line following process.
In fact the line following feature is implemented in a very simple way. Because the line is black is easy to isolate from the ground and this is performed using a simple binarization. Here are the steps of the implemented feature.
