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.

    @Lake,

    1) It sounds like you have not calibrated your transmitter in relation to the Sabertooth ESC. I believe that the Sabertooth has an option for auto cal at startup. You should check the Sabertooth operating instructions. Also, have you made sure that both your elevator and aileron joysticks do not have any offsets. In other words your trim values for elevator and aileron is "0"? Also, does your aileron bar in the radio cal go from about 1000 to about 1900 so that the aileron output is reasonably symmetrical about the neutral point. Same for the elevator bar .

    2) Are you using a 3-way switch to set modes manual, learning, and auto? If you are is the lowest position does the MP indicate auto when the switch is in that position? You might want to put your rover up on blocks and initiate the auto mode and make sure it does really go into the auto mode.

    3) There is a level function in the CLI setup. Use the Terminal Tab to get into the CLI. Type in "setup". When you are in the "setup" function, type "level". Before you hit return, use a bubble level to ensure that your rover is level in the X-Y planes. Then hit return and wait for the CLI to go through the level process.

    Hope this helps.

  • Gentlemen,

     

    I've just received and built my final product after messing around with a smaller version.  I've built a Gears SMP Platform with the APM2.5.  It has 4 independent DC motors; (ie. skid steering).  I am using a Sabertooth 2 x12 motor controller w/R/C input jacks.  I have 2 issues going on that I could use help with please:

    1. When in reverse, the right side motors seem to lag more than the left.  Also, if turning to the right hard, the right side go slower in reverse than if I were to turn hard left going forward.... 
    2. For some reason, I can't get autopilot to run after I've set waypoints in the Mission Planner and uploaded them.  I've checked the flight mode settings, checked the radio calibration and matched them up.  I had a smaller version working perfectly....
    3. I've also noticed that in mission planner, the APM thinks it's banking about 30 degrees to the right, but it's laying flat in the rover.  I've double checked mission planner to make sure that the orientation had nothing changed there....

    Thanks for any and all responses in advance!

  • @Joshua,

    Brief look, the store looks more complete and I see some shipping options.  I'll try it out fully later.

    Thanks,

  • Alan, that sounds like it was the old store. We have just taken it off line. Will you verify that you are on the new store: http://store.3drobotics.com/

    @Alan,

    Have you pmed Joshua Ott, who is the new Editorial Director and I believe is responsible for the various websites, about your problem with the 3DR store?

  • I am trying to order,

    only pre-paid Fed-eX, no UPS or USPS ground.

    No PayPal

    Now they don't have the cables I wanted to order.

    You will have to register a new account. I used my same user id and password as here.

    Hi All,

    I have been shifting my rover discussions over to the new ArduPilot Forum: http://ardupilot.com/

  • I ran my first mission today.  An once in a open field, the GPS worked fairly well.  All in all, very satisfied.

New rover advice

Hi, i am looking to build a new rover, but i need some advice on the chassis. I like the 4wd chassis/tank look and prefer it over the crawler/rc look.are those any good though? most people recommend crawlers.I am looking to get something from banggood, any advice will be highly appreciated. thanks

skid steer vehicle steering uncontrollable

Hi all, I have a skid steer robot using a pixhawk cube, one 1x15 roboclaw motor controller and a dagu wild thumper 4 wheel chassis. I have skid steering working so far, testing motor c and motor d tests works as described and the vehicle can be controlled in manual mode. However, upon using any mode other than manual mode the rover wants to shake and pivot on the spot, and it seems the steering PID controller oscillates and these oscillations get larger. i have tried everything but it is still…

Hi,I have converted a Traxxas X-Maxx into a rover using the Pixhawk Cube 2 controller kit with a Here GNSS.I swapped out the original X-Maxx remote controller for an X6R receiver and Taranis QX7 radio.latest version of ArduRover firmware installed as of 8/11/18.  The rover has an EZRun Max6 ESC. The problem now is the ESC control over the transition into reverse. The ESC is currently set to it's Running Mode Option 2: "Forward/Reverse with Break", AKA the "Double Click Method".What this mode…

Help! No throttle or steering response!

Hi all.I know this is an Adurover group, but Thought I would reach out and try my odds for some help as I'm perplexed by this problem. I have a Traxxas X-Maxx set up with a Pixhawk Cube 2.1 and the Here GPS. I'm using a Tarranis X7 remote controller and a X8R Sbus Receiver. I'm using QGroundControl with the latest, Pixhawk 1.8.0 Firmware with the Generic Rover airframe profile installed. As instructed, I have Steering servo wired into Main 2 and Throttle ESC wired into Main 4. Sensors are…
