Hi
Does the pololu 3pi robot allow for the addition of it sensors for wall detection of a maze?

Hello @Jcampsall and welcome to the RobotShop forum,

The Pololu 3pi Robot comes with QTR-RC reflectance sensors (line following sensors) that can be used to solve line mazes.

However, if you want to use distance sensors such as an ultrasonic or infrared sensor for wall detection you can also do that.

Thanks.
No a lot of space.
What are the small sensors I see in micromouse contests?

Could something like this be used:

3-Channel Wide FOV Time-of-Flight Distance Sensor OPT3101 (No Headers)

But I don’t how the 3-channel 6 LED scenario works :thinking:

Those are IR sensors, you can find more information about the hardware micromouse robots use here:

You could use that type of sensor for wall/obstacle detection. However, you can’t use that sensor with the 3pi platform because it doesn’t have an I2C interface (nor enough IO pins to simulate it)

But I don’t how the 3-channel 6 LED scenario works

You can find some examples here:
