I would like to know if the IR sensor system of the Zumo32U4 would work to solve a maze with walls.
I mean, does the system could be configured to measure small changes of distance (about 5 mm) in order to control the robot motion.
I’ve tried to reduce the Brightness Levels but i didnt reach the sensitivity I’m looking for (It’s was too big, I could detect changes when the difference of distance was about 10 cm).
Is it possible to do this with the Zumo32U4 as it is or some extra sensors are needed?
The IR sensor system on the robot is designed primarily to determine the direction of a target and, although it is possible to get some information about the reflectivity of an object (which should vary with distance), in practice we think it would be very hard to detect a 5mm distance change with them.
