Does anyone know of an alternative distance sensor than the Ultrasonic Range Finder that would work with Vex EDR and RobotC? The Vex Ultrasonic Range Finder has a lot of noise and is almost useless. I've tried three different sensors and they all perform poorly. They have trouble sensing most surfaces and the results bounce around a lot.
I'm only using the robot for personal use and won't be entering a competition, so I'm not worried about using official sensors.
Any alternative range or distance sensors? Thanks!
