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 did find # of satellites, and it hops between 12 and 13.

Thanks Thomas!

I'm getting ~ 3.75 m/s as I have the course measured at ~ 245m?

How do I find out how many satellites it locked and the HDOP?

Comment by Thomas J Coyle III on June 18, 2014 at 2:26pm


Good work!

Based on the time, it sounds like your rover is running around 6m/s.

How many satellites did you acquire and what was your HDOP?

I was able to acquire 12 - 13 satellites last year and had an HDOP of around 1.3.

My M8Q GPS arrived today, but I do not think that I will try to take it to the AVC as it still needs a 3DR configuration file that will work with it.

The weather on Saturday is supposed to be good with just clouds.

Did some quick testing today. The car now has single-sonar obstacle avoidance. Took me a while to dial that one in. Had to tilt much more than I expected and extend out the action distance to have it reliably avoid stuff. 

But the car is running the AVC course (sans actual boundaries and obstacles) in just over 1 min (~1:06). That includes slowing around corners and slowing where the barrels will be. My current speed looks solid, but on the conservative side. I might up it a bit, perhaps for later heats depending on how it goes.

Hi All,

I have just about completed installing a Pixhawk on a brand new Traxxas 4WD Slash roller chassis.

I believe that this 4WD chassis can be very competitive in the Peloton Class of autonomous vehicles and can be assembled at a reasonable price.

If anyone is interested in duplicating my installation on the Slash 4WD chassis, please pm me and I will start a discussion about the installation.

Hi All,

I just shipped my Pixhawk equipped Traxxas 2WD brushless Slash rover and its support equipment in a Pelican 1650 case to Boulder, CO for the Sparkfun 2014 AVC. It should be there by June 13 to the 16th just in time for my arrival there on June 19th.

The Porta-potties are where the start/finish hay bales are positioned when the AVC course has been laid out.

Did some testing at Boulder Resevoir. This is what the starting line currently looks like

My car may have tried to wedge itself underneath one of the porta-potties...

Thanks Thomas!

I'll give it a try. You find a longer reply here.

Best regards,

That command does work as I have inadvertently tested it before I knew of its existence. I had a curb strike during the Auto Mode that stopped my rover so I went to Manual and drove the rover back to the start and went to the Auto Mode. The rover, instead of starting the mission again, tried to go back to the last waypoint before the curb strike and complete the mission:-) I presently have the  MIS_RESTART set to 1. It is normally set to 0.
