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.

Hello everyone,I'm trying to design and build an "open source" radar system. The premise is that while we have the hacked Neato and the RoboPeak system, I've not found anything for outdoor use. So…Continue

Thanks Tom.

Hi Hugues.  There are 2 orientation parameters.  One for the pixhawk board and one for the external compass.  Have a look at these pages:

@Hugues,

You might have to orient the GPS/Compass the same way that the Pixhawk module is oriented on the chassis.

This sounds like a problem that might require assistance from Grant Morphett.

Pixhawk and GPS+Compass module orientation question :

-Pixhawk is turned 90 degrees clockwise relative to the front of vehicule

-The external compass+GPS is facing the front of the vehicle

I tried "Rotation_none", then "rotation yaw 90", also "rotation_yaw 270" with no success in having the front of the vehicule facing North (checked by looking at mission planner's HUD). I made a reboot and compass calib dance at each change. No joy.

Any ideas what I'm doing wrong ? (or known issue in rover code ?)

@Hugues,

I have bought all of my Traxxas Slash/E-Maxx roller chassis and hardware off of eBay from sellers with 99 -100% ratings.

@Tom,Niall, thx for your advice's. What online shop sells this e-maxx chassis and NEU motor?

Comment by Antonie Kruger on May 4, 2015 at 2:18am

@Niall, that's great. Made my day:)
You should paint some spots on the robot and replace the beep with a bark - would sound less like a south African taxi and more like a herding dog. I like your design.
Thanks for sharing.

@Hugues,

I built a custom robot for my farm a few years ago. The farm is all grass and has some slopes but no really rough terrain and after a few attempts I found that a 2 wheels driven by 11 amp wheelchair motors worked very well. FarmBoz Youtube

If I can be of any further assistance let me know.

@Hugues,

Forget the Wild Thumper as it uses the motor sleeve bearings to support the wheels.

I would go with a 4WD chassis like the Traxxas 1/8 scale E-Maxx with the brushless NEU motor and four wheel independent suspension with bearing supported half shafts.

You might even want to consider a 1/5 scale 4WD chassis that can carry bigger batteries for longer range and has a suspension that can get over the field furrows:-)

Hello,

I have to investigate on a rover platform for a customer who will use it in agriculture fields & forests dirt. What platform would you advise me to investigate : a wild thumper ? a tank tracked chassis ?

thx

Thanks, Mark and Grant.

I removed Mission planner, APM2, QCGround control. Re-loaded Mission Planner and now its all working again.

Good to know about the Geo Fencing (the large circles I see in Mission Planner).

Thanks again guys
