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.

What should the rover do when I switch to Auto mode?  Should the motor start immediately?  In my case, I have to manually move the throttle stick to control speed all the way to the first WP.The only…Continue

The Start/Stop function has been available on the APM for quite a while and is now working on the Pixhawk. Details on how to use the Start/Stop function can be found here: Start/Stop

Hi Thomas,

I am new to rovers and just starting to put pieces together.

I am looking for a way (if possible without mavlink) to stop a rover at some point while in Auto mission and to proceed the mission after some external input. Hence, the Start/Stop auto_trigger function sounds interesting. Can you provide some details about it?

My idea is to use something like CAM_TRIGG_DIST (which can easily be set in a CGS). Then after it is triggered and the signal is send to an embedded computer (RasPi, BBB, etc.) a Stop signal is send back to stop Auto Mode and, after some processing is finished, a Start signal is send to resume the Auto mission.

Is something like this possible. I already posted here and here but no replies so far. Then I saw your post about the ArduRover 2.46 beta :-)

TIA and best regards,

Hi All,

ArduRover 2.46 beta is now available for use:Rover Latest This beta release version has been updated for proper sequential triggering of dual sonars and has had the Start/Stop auto_trigger function verified for starting and stopping the rover in the Auto Mode (Sparkfun AVC requirement) without the use of an R/C receiver.

Thanks for the update, much appreciated. After conversing with Bot Thoughts it was beginning to look like a server issue as you have pointed out. I really like your discussion group and could not figure out for the life of me why it was deleted.

   Blame the rouge Google servers.  It some how got flagged as spam.  I'll buy you a beer after the AVC.  I wish all of the APM:Rover competitors good luck, and I'll let my rover and do the talking till then. :)

Hi All

Yesterday I had an interesting experience over on the Google Group diyrovers discussion group of which some of you are members.

I responded with a post to a member's Sonar discussion thread and within an hour my post had been deleted. This smacks of censorship.

To be fair, the Sonar post author sent me a gmail asking why I had deleted my discussion post because I had brought up some useful ideas he had not thought of.

I told him that I had not deleted my post and that they must have a rogue moderator who does not like me personally or heaven forbid the ArduRover2 Developers.

Hi All,

I would like to report that the Active Braking function is now working as we would like it to work which is awesome.

Today I tested the Active Braking function on the latest ArduRover2 v2.45 beta and I found that the Active Braking function lets me run my Slash rover from a standing start to 9m/s and then negotiate a hard left hand turn at 3m/s without rolling over.

The performance is simply astounding compared to no Active Braking.

Please be aware that if you try this beta firmware at 9m/s you will be going at nearly 20mph so any navigation failures will not be pretty.

Here are my parameters for a Cruise Speed of 9m/s for my Traxxas Slash Rover:

CS  9m/s (19.8mph)
STG 40% (Speed_Turn_Gain)
STD 15m (Speed_Turn_Distance)
BP  75%
SE  1m/s
The new Active Braking parameters are:
Braking Percentage and Speed Error. The Braking Percentage is self-explanatory while the Speed Error is the velocity difference between the requested speed and the gps speed that causes active braking to take affect.
Please be aware that you will have to experiment with these parameter values to get the right combination for your vehicle.

Hi All,

Tridge, Linus, and I have been working diligently to perfect the ArduRover2 Active Braking function and after this morning's code hacking hangout I feel that we are now very close to an effective active braking function.

If all goes well with both the APM and the Pixhawk active braking testing on my Home Depot test course, I believe that Tridge plans to release a ArduRover2 version 2.46 once the active braking data has been vetted to determine that the braking performance functions as expected.

Hi All,

For those of you looking for a reasonably priced skid steering type tank chassis checkout this Sparkfun tank chassis: Link

Hi All,

For those of you who will be competing at the Sparkfun 2014 AVC your vehicle proof of concept documentation must be submitted by the end of May I believe.

I received word yesterday from Sparkfun that my Slash Rover passed the proof of concept requirements and has been verified to run in the Peloton Class.
