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.

Nice to hear you got your rover working and are satisfied with its performance.

We will have an L1 version of the ArduRover2 code available after it has been alpha/beta tested over the next several weeks.

I have just trim my buggy!

My goal is to have a moderate speed and good navigation.

Regarding navigation I saved the points 3 days ago and did all the tests with same points.

The precision differs  from 30 cm to 2,5 meters. It depends on  weather conditions.


For driving, speed and heading this are my PID´s :

Thanks for the link. I'll check it out.

Turnigy also makes a servo reverser and if I remember correctly, it will slow down the servo as well so if you use 3 Y cables, one would split front and back servos, another splits the two fronts, and the other goes to the reverser. The reverser should allow for two servos to run off the one signal.

Here's the link.

I thought about that as well.  Looks like it will be a fun filled weekend :-).

You could easily program an Arduino Pro Mini to reverse the servo direction and proportionalize it to your requirements.



Comment by Mike Wilson on May 17, 2013 at 11:05am

That's what I just found out as well TC.

I'm going to look at modifying the APM code to output a mixed PWM signal on one of the unused output ports that can be used to steer the rear wheels.

The skid steering function in ArduRover2 is for throttles only. It assumes that there is an ESC attached to each throttle channel. Skid steering does not provide a steering output in the traditional sense.



Comment by Mike Wilson on May 17, 2013 at 9:34am

@John Moore,


The problem is I need to drive the rear servos in the opposite direction and also at a different steering ratio. I use only 40% on the rear wheels.

Thanks for all the suggestions guys :)

I loved NitroRCX  cars, especially at that price but they don't ship to India. Is any kind soul willing to drop-ship for me?
