Before Posting an Issue

Hi All,

Before posting an issue or a problem in the ArduRover Discussion Forum, please check the wiki table of contents, review the firmware release notes in the subforum, and search that subforum for existing answers to your question. Help avoid duplicate threads by finding other members with the same issue and their solution.

When formulating your post, use a descriptive title such as "rover will not navigate to waypoints in the Auto mode" (not "HELP!" or "Problem").

Please include the following information to help diagnose your query:

  • Describe the problem you are having. What is the expected verses the observed behavior?
  • Provide hardware information such as the brand and version of your autopilot, GPS, radio, and compass, as well as any other pertinent details about your rover setup.
  • What version of the APM: ArdurRover2 firmware version are you running?
  • For navigation issues, provide your tlog and/or dataflash log. Click here for instructions on retrieving a dataflash log.

The rover works completely in manual mode, but whenever I switch to auto or RTL the rover just turns in tight circles. I get an error message "Error compass variance". I recalibrated the compass, but…Continue

Hi All,

The Rover T3 competition has closed for the present T3 competition 100m x 100m bow tie course.

Hopefully more of our members will want to compete in future T3s as they are a lot of fun as well as a way to get the most out of your rovers.

The Auto Mode will also default to the Hold Mode at the end of a waypoint Mission or with the loss of the R/C connection.


Yes, you are correct that the rover will stay in the Hold Mode when going to the Auto Mode if there is no Mission loaded.

Yeah, that too.

Comment by healthyfatboy on August 5, 2015 at 8:36pm

Okay, I figured it out. Unless you have a mission loaded, you can't get into AUTO mode. It always displays HOLD. I'm sure the GPS lock also applies like you mentioned.

I too noticed that flight mode setting quirk.  I'm new with the Rover and haven't studied the modes yet,  so I'm no help yet. 

Comment by dr0n3droid on August 5, 2015 at 8:32pm
AUTO will default to HOLD without a GPS LOCK.
If that helps?

Comment by healthyfatboy on August 5, 2015 at 8:29pm

Hmmm...I'm running Rover v2.5 right now and trying to set up the mode selection properly. I have it going from Manual to Learning just fine. When I set one of my switches to the proper position for Auto, it shows in the Flight Mode setup screen that I'm on that mode but every indicator of the current mode shows it going to HOLD instead of AUTO. I have no idea why that is and it's giving me fits trying to run an AUTO mission.

I have my FS Action set to HOLD, have Throttle FS enabled, and all that works great after the 1 second timeout I set it to.

It doesn't seem to matter what Mode position I put AUTO on (mode 1-6), when I put my switch in the proper position, it always goes to HOLD instead of AUTO.

Is anyone else having this problem?

Comment by Bo Barry on August 1, 2015 at 8:15pm

Thanks,  I had just found that info & concluded the same.  I'll just add it to a little Arduino and have it honk the horn occasionally,  and then louder when it gets near a car.  I'm crazy enough to send it on a mission in our neighborhood.  :)  Thanks again. Bo

Bo, this is the sonar setup page.  At the moment the sonar's guide the rover to go around an obstacle.  There is no way to do what you ask unless the software is changed.

Comment by Bo Barry on August 1, 2015 at 7:10pm

 Switching from a quad to a Rover temporarily.  Where can I find info on how to 'use'  the sonar output to say sound a horn or stop the vehicle?   Bo
