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.

  • @ KM6VV - It was a typo Alan Was supposed to be Stream Bank. My list was directed toward Rich. My tracked rover was designed for purposes other than RoboMagellan. It was a designed as a rescue vehicle to operate in hostile environments.

  • I don't know about all of the items on your list, but a 6WD with independent suspension on each wheel can accommodate most of the items on your list. 

    Steam Bank?   I'll keep out of water.  Cliff? I'll stay away from the cliffs.  We'll see.  That's what RoboMagellan is about!

  • @Jimmie D,

    "A list of what if's to think about:

    What if your rover encounters a?:

    Cliff, tree, curb, picnic table, steep grade, animal, another rover, heavy grass, steam bank, water, etc."

    Yep, got most of that covered. The GPS and the mag compass are what I'm retaining from the Ardupilot design. I'm also modding the code to deal with two sonar sensors and some LED distance sensors.

    The environment that robot will operate in is relatively well defined and constrained. Basically it going to patrol the garden.

    I've also added a hardware PPM mux. The PPM encoder the Ardupilots use are overkill for my application.

    I'll probably start a blog to show it off in a few weeks.

  • Has anyone thought of a "neighbourhood watch"-type rover?

    I was thinking they could be given a route, and have a/some camera(s) running with a public URL for citizens to watch.

  • @KM6VV: If not mentioned yet, the Blackfin Camera is a robotics camera system (similar to CMUcam or AVRcam). The full name is Surveyor SRV-1 Blackfin Camera

  • @ Randy

    Sonic, IR, Accelerometer, Compass, and Tactile. Had encoders installed but never activated them. Quit working with my rover in September 2006, after being diagnosed with Lymphoma. All clear now and back to playing with my toys.

  • I didn't see any mention of a JPEG output. 

    Look at something like the BlackFin Camera, that's what you're describing.  It can use a WiFI link, or serial.

  • FYI

    Have a look at this camera which may be a good fit for our rovers.

    HD on the card but composite video on the output.

    Is it possible to stream that video to my laptop and use RoboRealm to send back commands on where to go? WiFi or Xbee?

    @Jimme

    What other sensors do you have. Sonic, IR?

    I have three sonic sensors with the center one on a pan/tilt

  • @ Rich - "I'm making a shield for a Arduino Mega with just interfaces for the GPS and the mag compass. I figure that's all I need for ground operation."

    A list of what if's to think about:

    What if your rover encounters a?:

    Cliff, tree, curb, picnic table, steep grade, animal, another rover, heavy grass, steam bank, water, etc.

    How do you avoid these?

    Think about that for awhile and post some of your thought and we will explore the solutions.

  • @Jim - Well I can hardly call myself a "youngster" but I am new to this game.;)

    @ All - I have APM installed and pretty much ready for autonomy tests - just waiting for a UBEC I ordered to clear up a GPS interference issue, and new Tx.  Wondering... do the mode switch on Tx and mode select in MP work together, that is, "override" each other so to speak? I started out with the 2 channel Tx that came with the boat so I have not played with a mode select switch yet.  I just set all modes to Manual in configuration to avoid any surprises.  Also, I set Max Throttle very low for tests but when I select Auto from MP it seems to go to full throttle.  Is this something that will clear up when I get my 4 channel Tx?

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…
