Re: IR/ultrasound sensing angle

Just some of the applications they are used for include measuring the range to a golf hole, or the distance between interior walls. They are usually based on a class 1 laser that might be FRC legal depending on the rules (not guaranteed though). Class II lasers are probably right out for FRC use. They tend to be expensive devices and are difficult and complicated to integrate with a control system. Real expensive ones can be had with Bluetooth (not FRC legal).

You can also develop a DIY cheaper alternative by coupling a cheap laser pointer with a detector as a retro-reflective sensor.
