Over the past few days, I have tested several different configurations of sensors to give the rover the ability to navigate on its own. The most effective setup ended up being two ultrasonic sensors on the front of the rover and an IR sensor on each side. I’ve tested it several times and these sensors seem to be picking up about 80-90% of the objects in the robot’s path, which I am satisfied with for now. The next step is to add bluetooth controls to the rover so it can be driven using an app. I will start by using a bluetooth serial app that I already have, but I will eventually build a custom app as well.
