Hi stujoe,

Welcome to the RobotShop Forum.

When your robot starts running in circles and gives you a two-tone ‘uh-oh’ sound, does it follow that up with a specific number of beeps? Often times this will indicate the problem the robot is experiencing.

Sometimes the sensors can get dirty and need to be cleaned off. We suggest you try to clean up under the bumper along it’s whole length using compressed air. Also stiffly press the bumper in several times to see if that will free up any debris that may have accumulated near the sensors.

If after trying the above the problem persists, your robot most likely needs to be repaired. Please see here for more information on our repair service.

Or, if you prefer to repair the robot yourself, we suggest that you consider purchasing bumper sensor boards for your robot. Please note this part is only if your robot is giving you a nine-beep error code and spinning in circles. If it’s giving you something else, it may need a different part; let us know and we’ll advise you appropriately.

If you have any questions, please do not hesitate to ask.

Thanks,

Hi stujoe,

If cleaning it didn’t help and you are in fact getting the nine-beep error, then the bumper sensor boards are likely defective. In this case it would need to be repaired, either by purchasing the parts and installing them yourself, or by sending it in for repairs.

We hope this helps.

Thanks,

The part number is RB-RBO-28. We linked to the part in our first post, but we’ll put it below as well. The cost is posted there in the link. You may have to test if it’s the left or right sensor, or to be thorough, you may want to purchase two and change them both to save time, in case you have to switch the sensor from one side to the other. The link below also gives you instructions as well as which tools you will need.
