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.

How should we handle reverse in ArduRover?

Started by Andrew Tridgell. Last reply by RoboBill yesterday. 44 Replies

I'd like to add support for the rover using reverse in auto mode, so if it can get somewhere faster by going backwards it will. So I'm looking at how reverse is setup in the ArduRover code, and…Continue

ESC seems armed but I get no throttle or movement when I go to auto mode.

Sounds like I am totally mixed up an will need to do more looking, an maybe some trial an error.  With hope of keeping the magic smoke in the devices.

@ TC

I thought that I understood when using PM, I had to remove J1.  An then the ESC would power the servo's via  the Output Rail.  PM would power the Receiver an the GPS.  Which is supported by this line in the link you gave me in the 3rd paragraph above the warning....


"If the jumper is off, the board is powered from the Input rail, but the Output rail will need its own power source. This configuration is used if you want to have two separate power sources in your aircraft, one powering the servos and the other powering the electronics."


I am under the impression that the Input Rail gets its power from the PM.

It is my understanding that you cannot power the pan and tilt servos from the APM when using the PM. You must power the pan and tilt servos separately, but the signal and common ground with the servo power can come from the APM. Since you are not using the main battery to provide power to the PM you will not be able to obtain the main battery voltage and current usage. I would use a 2200mahr LiPo if you are powering both the PM and a transmitter/camera with the aux battery.

Take a look at the Wiki:

 I have a thread over in Ground Vehicle which I posted a diagram of my planned power an data routing.  Would you mind looking at the bottom of page 2 an seeing if I am on the right path?  I don't want to start a new thread as I will be dumping that thread in favor for a build thread here this weekend.

@TC, Thank You.

As far as I know, you should not run the USB and the PM together. Since you are using the PM I assume that you have removed the J1 jumper?

I use the USB to power the APM when I am programming the parameters using the MP. I usually use the PM when I am out testing with or without my telemetry module.

Planning on installing the APM 2.5 into my RC this weekend.  I have pre tested it on my Win8 netbook by connecting to the USB port.  Once the APM is in my RC, can I have the APM 2.5 powered by the PM an connect the USB cable?  Or do I need to unplug the power from the APM prior to connecting to the USB port?

I have a Traxxas E-Maxx which is similar to the E-Revo in that the Brushless motor is mounted in the middle of the chassis. Since I was not planning to put a body on the chassis, I mounted a plate on top of the body support/shock towers and then a second plate above that to house the APM, GPS, compass, etc. I wanted to get the APM and compass as far from the motor magnets as possible. The rover I am going to run in the AVC is a 2WD Slash that has the motor in the rear and is easier to work with than the mid-chassis motor rovers.

You can see some pictures of my E-Maxx and 6WD rover chassis here:

Hey guys, might be getting a E-Revo in the near future, can it be converted to ArduRover usage? i.e does it have the space ? Or do I have to add stacks to add the APM?

Comment by Thomas J Coyle III on April 16, 2013 at 1:32pm


After you hit the reset button on the APM try clicking on the Terminal Tab to restart the CLI. You should get the ArduRover v2.40 CLI prompt. Then select Test under the Terminal Tab and see if you can use any of the test commands to see what is going on with your APM. If you are not successful, then you might have a defective APM and should contact
