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.

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.

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.

@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?


Comment by John Moore on May 17, 2013 at 8:06am

@ Mike,

Probably your easiest method to accomplish this would be a server wire splitter.  Allowing one steering ch to drive 2 servo's.

Hi guys,

I'm looking for the best way to setup 4 wheel steering with the APM.  My Traxxas e-Maxx is setup with 4 servos and I understand that the standard APM code only has a single output for steering.  There are lots of spare outputs so I don't think it would be too difficult to add code to mix PWM signals and invert them for the rear steering.  Has anyone already done this?  I would prefer not to have to use an external mixer.  Since the new APM code supports Skid Steering, could the skid steering output be used somehow?
