Im doing a little project and im looking for some advice. I am converting a RC car to an autonomous vehicle and the idea is that it should be able to drive in a small scale track that simulates a traffic situation which i have constructed. I want it to be able to follow the line between each lane, much like the course correction function for autopilot in newer cars. I would also like it to be able to tell the difference between 2 color of lights, simulating a traffic light.
If anyone can recommend some sensors that would allow me to accomplish this or simply tell me if its not possible then i would appreciate it alot.
