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.

Steering ardurover without servo

can we control the brushed motors using brused esc such that, if we want to reverse the rover, then can we rotate the parallel motors in opposite direction?Continue

i am newbie to ardurover, and want to build an ardurover from scratch with brush motor. does the APM 2.6 can directly control brush ESC, if not, what is the modification should i made to apm.Regards!Continue

Hi Guys, I recently acquired a Dagu Wild Thumper 6WD chassis and motor controller. I intend to use it for an autonomous rover project with one of my APM boards, - from Dad to Dad for Xmas :)

I trust all had a blessed Xmas and have peace and prosperity for the coming year.

Hi All,

I would like to wish all of the members here a safe and happy holiday!

We have a lot to look forward to in 2014, especially auto tuning and the Sparkfun 2014 AVC.

Regards,

Hi All,

It may seem like there has not been much activity concerning the ArduRover2 firmware development as there has not been any recent updates to the code. However Tridge, Linus and I have been testing the latest ArduRover2 v2.44 beta 1 firmware to see how it performs and to establish baseline values for the operating parameters that have the most affect on navigation performance.

Presently we are trying to get a good balance between straight line performance (minimal weaving) and tight turns in the chicanes. Basically high NAVL1_PERIOD values give good straight line performance, but result in wide turns in the chicanes. And just the opposite, lower NAVL1_PERIOD values cause weaving during straight line navigation, but result in tighter turns in the chicanes.

Therefore we are shooting for a balance between the NAVL1_PERIOD, the STEER2SERV_TCONST, the STEER2SRV_D, plus several other less influential parameters that will result in good straight line navigation as well as robust chicane performance.

More to come as we continue refining those parameters.

Hey everyone, my adrurover has been off line for some time.  Have been dealing with GPS accuracy still which I have concluded its due to the tight confined space I have.  With the drone an gps only 2 to 3 inches away from the brushed motor, I am guessing thats where my issue is.  So I am using that as an excuse to buy a new crawler.  A 1/5 scale Exceed MaxStone with motor on axle configuration.  At 33 inches long, it should give more than enough seperation between the drone hardware an motors.

@mikel-ange,

I do not know of a twin centered joystick transmitter with 5 to 6 channels, however I suspect that you can add springs to the non-centering joystick in a Mode 1 or 2 transmitter to make it perform like the centering joystick. Though you might have to remove the ratchet from the throttle joystick axis. You might want to make this project of yours a discussion so it will not get lost on the Comment Wall.

Hi All,

At last night's ArduRover2 code hacking hang out Tridge improved the speed of the APM MP parameter download and continued to optimize the firmware function scheduler code. So you can download the latest ArduRover2 v2.43 code at: ArduRover2 Latest

Tridge also walked me through setting up the PX4 code for a rover chassis using a PPM serial receiver. As a result I will be adding a new section to the ArduRover Wiki that explains who to set up the PX4 for use with either PPM encoders or receivers that produce PPM serial outputs.

Hi All,

Tonight Tridge and I corrected an issue with the ArduRover2 v2.43 PX4 code. The Mavlink connection between the PX4 and the MP worked great when using the USB connection but failed when using the telemetry radios. Tridge made a correction to some of the Mavlink packet coding and we now have a functioning Mavlink PX4 to MP connection over the radio telemetry link:-) The updated ArduRover2-v1.px4 code should be in the latest ArduRover2 code repository.

Regards,

Hi All,

Looks like we will probably be able to do a new release of the ArduRover2 code here shortly. Tridge made a minor improvement to the steering function in the Steering mode code yesterday that needs to be checked out today before the release. As soon as that improved part of the code is vetted there will be a new release.
