<p >This is part of a school project for Projects I class. It's basically a black line follower robot that is capable of stopping in front of an obstacle or reaching the end of the route (symbolized by when both line sensors detect a black line). The vehicle can listen to a command received by the serial to start or stop the route.</p><p >The full project consists of controlling this vehicle based on traffic light status that will be detected using an Android smartphone in a controlled testing environment. I'm fixing some stuff before uploading the other part of the project on to GitHub, but when I do, I'll post the link here.</p>
