Essential to any robot learning kit is a line follower. This week, we are introducing a line follower sensor for the Raspberry Pi, the GoPiGo Line Follower. A line follower is an easy way to direct your robot around the floor of a classroom, your kitchen, or your office. Just lay down some tape and start the line following program!
The line follower can follow black lines on a light background, or white lines on a dark background.
A line follower is one of the most prominent kinds of robots. You can build this line follower for your Raspberry Pi in under 10 minutes with our getting started guide and video. The line tracker allows you to build a robot to follow a path that is pre-marked with tape, paint, or a marker, and allows you to control the robot indirectly while it is moving autonomously. The line tracker turns the robot into an autonomously navigating machine that follows a line-marked path. By drawing a line in front of a Raspberry Pi robot with a line tracker, you can dictate the travel path, directing the robot to go without using any control. The Raspberry Pi Line Follower uses five line trackers, with the middle sensor aligned directly above the line, to give you precise and quick control of the robot.
Here is a quick introduction video to the GoPiGo Line Follower.
You can find software examples in Python in Github. More to come soon!
