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.

ArduRover without steering servo

Hi, I would like to build a rover without a steering servo but rather with 2 motors (left+right) for the steering, just like a tracked vehicle.Is there an ArduRover firmware that supports that kind…Continue

Hi All,

The skid (differential) steering in ArduRover2 stable version v2.46 is broken and our Developer/Programmer, Tridge, will not be available to fix it until after the AU OBC.

Please use either v2.44 or 2.45 from this repository Link

@Michael,

In some instances you have to use the "reverse" check box for either the ailerons or the throttle when in the Auto Mode compared to the Manual mode where you change the servo output direction in the transmitter.

Thanks for the reply Thomas.

I got it figured out.  I'm using a custom arduino based mixer. I had the throttle reversed. I adjusted my mixer and things look good now.

Cheers..  \o/

@Michael

What value do you have your CRUISE_THROTTLE set to?

What value do you have your CRUISE_SPEED set to?

What value do you have your WAYPOINT_RADIUS set to?

How far is your first waypoint from the starting (home) point?

This is my first time setting up an APM,  

 I have everything working in "manual" mode good.

Throttle and steering respond to my radio and from the ground station joystick.

But when I go into "auto" mode, the steering is responding but I get no throttle, no forward speed.

I setup the configuration to what it says in the ArduRover setup guide. at   http://rover.ardupilot.com/wiki/configuration-2/

But it looks like there is some information missing from that page, It stops in mid word.

so I went on to here;

http://rover.ardupilot.com/wiki/tuning-steering-and-navigation-for-...

and set the parameters as described.

No Joy.....   Steering movement but no speed. Can someone tell me what I am missing please?

Thank you.....

Hi All,

I think that once Tridge is done with the AU Outback Challenge, we plan to release a stable ArduRover2 v2.46.

The new release will have the active braking and throttle slew rate adjustment functions.

Stay tuned:-)

@FD,

We have talked about implementing optical flow for the Pixhawk equipped rovers and that could possibly be in the mix for next years Sparkfun AVC competition.

TCIII ArduRover2 Developer

Comment by FD on July 31, 2014 at 9:55pm

Hi all, has anybody ever thought about using optical flow for rovers in GPS-denied environment (such as indoors)?

This thread reminded my again of that possibility: http://diydrones.com/profiles/blogs/adding-optical-flow-to-the-mix

Any thoughts or even experiences with that?

Regards,

FD

@Michael,

Some excellent observations and thoughts on future low cost (relatively speaking), improved heading accuracy GPSs.
