Hi folks, I'm want to develop an automated car that always moves forward, and turns when it reaches obstacles.
I have doubts about what kind of sensor of proximity should I use. I don't need to know the distance from the obstacles, just to turn the sensors ON/OFF while they get close to the walls.
I've heard that the IR sensors changes their range of activation accordingly to the color of the surfaces of reflection, and that both ultra-sonic and light sensors doesn't activates if the surface of reflection has a big angle with the sensors (this is my most important doubt).
Which of these do you recommend since the car should work outdoor??
