Re: Ultrasonic Interference
We found this to be a problem as well. Even when the wires for the VEX Ultrasonic sensor were physically moved >1 foot away from any RS775s or wires for these, we would get erratic readings. This was unacceptable for the application (keeping the robot from slamming into the wall), so we gave up and used other options (using light sensors to detect the line at the end of the zone, and using encoders to dead-reckon).
