My ultrasonic sensor for my robot is coming up with a wide array of different results when it is being used. I can get a result that is very high and low without the robot moving at all. In the link below you can see the readings of the sensor and that the robot is not moving while it is being used.
On top of this issue, this is happening to all of my robots. I am a teacher and every one of my student’s robots are having the same issue.
The robots and sensors are up-to-date, I have tried changing wires, sensors, and the robot brain.
Please let me know what you think.
