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.

I was wondering why compassmot hasn't been integrated into the rover code.  I read the comment that says it's not needed but I've been testing a rover with some BIG motors drawing lots of amps and I…Continue

I have put this on the APM forum, but got no replies, so here goes...

In MP 1.2.99 > config > full param list and using the drop down list on the right hand side of the screen:
Selecting 3DR_rover, beginner, intermediate, or advanced and then clicking the load params button, I get nothing but a blank screen. Other selections do show some params.
I uninstalled and re-installed MP and got same results.

Any help would be appreciated.

Please don't worry. I know someone will get around to it. I just enjoy fiddling with parameters.

Comment by Thomas J Coyle III on April 5, 2014 at 6:25pm


The undocumented parameters may have EKF in the parameter name. If so, then they are for use by the firmware when EKF is enabled. Are you using a Pixhawk as EKF only works on a Pixhawk.

As far as the skid steering not being functional, I wish that I could help you out, but I no longer have any skid steering rovers around. I had two, but they belonged to some clients I was working for and they have gone to their respective owners.

What symptoms are you seeing with the nonfunctioning skid steering code? About a week ago one of my clients loaded a v2.45 beta version onto his Wild Thumper and it appeared to work okay. Whatever has changed, must have happened over the last week

Yes I checked that and it was set at 1. I also saw a whole bunch of undocumented parameters... way cool.

Comment by Thomas J Coyle III on April 5, 2014 at 2:29pm


Did you make sure in the Full Parameter List that Skid_Steer_Out was still set to 1?

Not sure where to put this so...

Just for fun and to learn more, I tried the latest rover firmware and it appears the skid steering is not working. So I went back to the 2.45 with skid working. NBD

I don't care, this is a decent quality 5 ch that I can afford with a 3 position switch.  Much better than my alt at hobbyking.  As soon as possible, I am buying one.

Havent even bought the new RC, an am already to get the

This channel 5 switch "upgrade" makes me wonder what other undocumented changes were made to the DX5e line and other Spektrum models...
