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.

Hello, I've been reading about ArduPilot for a long time, but I never had the opportunity to buy one, today finally I could buy an APM 2.6. My first project is to build a simple rover using this…Continue

Please integrate compassmot

I was wondering why compassmot hasn't been integrated into the rover code.  I read the comment that says it's not needed but I've been testing a rover with some BIG motors drawing lots of amps and I…Continue

To All,

Regarding Pooja question, does the APM only accept waypoints when in "Learning" Mode?



Have you tried changing the Manual mode on the switch to Leaning (giving you Leaning an Auto) an tested loading Waypoints an switching to Auto?

Waypoint Radius of 1 set.  Dealing with Flight Modes now.  I have some questions/issues regarding it in my build thread.


Sun just came out, going to test now.  Will have more to follow.

Yes, you can use the Flight Planner tab to create and upload waypoints to your crawler. I suggest using a waypoint radius of 1.



Comment by John Moore on April 27, 2013 at 8:36pm


Thanks for the heads up.  I didn't stop my crawler when I did my test.  I will test again tomorrow an see how that works.


If I am not mistaken, I am suppose to be able to set waypoints in Mission Planner an load them.  Correct?



Comment by Thomas J Coyle III on April 27, 2013 at 8:29pm


I was out creating waypoints with the momentary switch today too and had good success with the process. I stopped the rover at each point that I wanted to create a waypoint and moved the switch from low to high and back to low again in about a second. Worked great.

I got the APM 2.5 hardware installed today an was able to test it out.  When setting WayPoints via the momentary switch, how long do I have to hold the switch?


I will be posting pictures an better explanations of my progress on my thread later tonight or tomorrow.

Im new to the Rover group, as I fly choppers and fixed wing stuff until now...

Im retrofitting a Bot with stuff to use as a test bed for the flying drones and subsystems therein...since its all relative, and if the Bot bumps a wall or falls into a hole, its gonna be  a lot cheaper than searching for a scattering of expensive helicopter pieces, lol.

My Bot was a fancy robot toy thingy from the late 80's my buddy had as a kid, and consequently was about to discard a few months back....saved from the trash heap...or Jawas...either way, it makes a hell of a rover platform with its tank treads and 18 inch stature. (good for sensors and antennas, cameras, etc)

As a toy, it was probably fun, but its electronics suite was primitive AM 49mhz garbage that was about as useless and reliable as a cheap TV IR remote control.

But it has grasping arms, articulated waist/torso, tank tread locomotion, and shot darts from a 3-round gatling gun in its chest.. among other things.

I added head/neck articulation, stepper motor actuation for the arms and waist, and some peripheral doodads for camera panning/tilting, along with more serious Bot hardware like Arduino motivation controller in base tray (housekeeping unit) and another Arduino for comms and navigation in its head area (the higher end stuff) for working with the GPS module, Sim900 cellular unit (backup comms and control ---"why wont you come home, robot???"--), laser rangefinder, sonar ping unit for close range sensing, PIR sensor for detecting those pesky carbon units nearby (animals or humans), gyroscopes and accelerometers ( I said this was a UAV testbed afterall ;0) )

and pretty much anything R2-D2 could have needed (except its hologram projector)

It should be a fun and rewarding side activity developing her (yes, a she) and, as stated earlier, saving some $$ in my UAV systems development.

Heck afterall, when shes done (are they ever really done?) or at least done enough to be usefull, she will be employed as watchdog, household errand girl, beverage and snack tender, and maybe even used for periodic cat discipline or remote feeding/watering maid while out of town.

The Skid steering is great, but I will need to be able to turn on the spot.  Actually, In testing with just R/C and a RoboClaw dual motor driver, my son was able to spin on spot on his hardwood floor. 

My 6WD didn't make it into the Robomagellan, other stuff came up like getting a new job. 

Still working on the ratcheting problem in my timing belt drive, new belts arrived today.

the throttle and roll assignment you are describing should be okay.

Yaw is not used for Steering control on the rover.

Hi All,

For those of you who would like to integrate a BeagleBone mcu into your rover project, here is a look at the new BeagleBone Black:

It is only $45 which is about half the price of the original BeagleBone mcu.
