IR sensors are not working

[jenvander]

Hello! I purchased a Rokit and the IR sensors are not working. They always read "1" whether on white or black (I loaded my own program to debug). Do I need a new board, or is there a way to get these working?

I've also noticed (with more than one Rokit) that the motors often move at a different speed, so the DCMove(forward, speed) doesn't really work. I'm using this with middle school students, so I'd like to keep the code simple and readable for them. Is there a way to calibrate the motor speeds to get them in sync?

@jenvander Can you paste your code in here?

If you could post a video so we can see what's going on it'll provide a little more clarity regarding your issue.

I've tried that calibration troubleshooting, it didn't work. It doesn't detect differences no matter how I calibrate it.

Hi @jenvander :

Please use the following link to try troubleshooting your calibration for your bottom IR Sensors:

For the motor issue:

you might want to check that there are no objects impeding the movement of the robot.

You might also want to try using slower speeds when using the DCMove command. We do have functions that allow you to independently set the speed for the motors.
