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.

  • Hola a todos,gracias por la invitacion al grupo.-Mi interes es poder desarrollar un ARDUROVER,necesito si alguien me  puede guiar paso  a paso , en como comenzar y que debo comprar ; necesito construir un vehiculo que siga diferentes  waypoints y pueda ir tomando datos  de sensores con otro modulo ARDUINO y enviarlos a un computador.- desde ya muchisimas gracias.-

    I don't know if this helps but it's a program someone wrote that I've held onto for the Arduino. It'll read up to 8 servo channels for you and display them in the serial monitor. I'm sure you could easily modify it for an 16x2 LCD so you wouldn't need a computer.

    @Flavio,

    Nice to hear of your success with your boat. Nothing like converging on a perfect solution. I also have found that my throttle cruise value should be around 58 otherwise the E-Maxx will go too fast! I will look in the Advanced Parameters as you suggest.

    Regards,

  • @TCIII

    Happy to read good progress and a succesfull setup method

    I dont have here the boat to point you the slew rate parameter but I'm quite sure it is at the end of the aadvanced parameters in MP, try to search around "R" voices.

    A little bugs found on APM startup, my Turnigy marine ESC sometime enter in setup mode instead of normal running mode, I fix it by add a small trim of throttle radio output but it is not normal as it doesnt appear if rx is directly connected to esc. probably during startup amp generate some pwm spike and the esc read them as radio setup mode.   

  • Hi All,

    Today I had the first Arduboat field test, 365 mt of auto mode with 11 WP.

    FW 2.31 (little mods for boat and for Echosounder readings ).

    Still some steering problem at low speed but it is a mechanic problem, I'll fix it increasing rudder dimension.

    Parameters are: Cruise Throttle 57 ( I swap two phase and now I have positive value ) Roll P 0.4  I 0  D 0.1

    No slew rate or booster.3692560853?profile=original

    Hi All,

    Can anyone point me to the ArduRover Parameter in the MP that controls the throttle slew rate? Nothing in the Parameter table seems to be a slew rate for the throttle.

    Regards,

    TCIII

  • OK, I can use the PWM read function, I've got the other ones covered.  Too bad this store is out of stock.  I'll look around a bit.

    It would make a great PIC or Arduino project, if I had the time!  Can't take much to knock out a little code to read a servo and display the pulse width!

    Best regards,

    Alan

    @Alan,

    Maybe "analyzer" is a bit optimistic.

    Here is what I have: http://www.bphobbies.com/view.asp?id=A0320107&pid=D0736126 which is what you have made reference to in your comment. Works great. Wouldn't be without it. Decodes PWM output into ms and can produce PWM from <1ms to >2ms.

  • @Thomas,

    I see a GWSRMT001 servo tester, but not an "analyzer".  Do you have a link, or model number?  The tester I see allows you to drive a servo, but it would be nice to have a "meter" for an R/C PWM signal, which I suspect you have.

    Regards,

    Hi All,

    The IR range is no longer in the Console Window. It appears that Tridge made a change so that it shows up in the sonar test in the CLI test suite. Works great!

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…

Traxxas X-Maxx ROVER ESC advice

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…
