Detecting distances is a foundation of autonomous and guided robotics. It doesn't matter how smart your robot is if he keeps running into things!

We've got two different technologies of distance sensors; Infrared and Ultrasonic. Both have their advantages and we've got options for both.

Infrared

Infrared distances sensors are capable of precise and accurate distance measurements, however, they can be affected by certain lighting conditions.
