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.

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

Jared,

It depends on what data you want to get out of it. If you want full autopilot functionality, you're better off with APM 2.5. ArduIMU is an older product and is no longer being actively developed. 

But if you just want attitude data, ArduIMU works fine.

Hi Group,

I'm new to all this, I have a APM 2.5, is it possible to use it as an IMU like the ArduIMU or am I better off just buying the ArduIMU?

I have been testing my Slash rover with the latest ArduRover2 v2.24b code and the consistence of the waypoint tracking is exceptionally good. Tridge and I have been working on speed control, which can be done in the Mission Planner, at various points on my vehicle test course here in Florida. The object is to get the rover to have the fastest average time possible through the test course which can be translated to the actual AVC course performance.

Regards,

TCIII

@ Thomas

thank you for the information.

@MVeloso,

Nice to hear you got your rover working and are satisfied with its performance.

We will have an L1 version of the ArduRover2 code available after it has been alpha/beta tested over the next several weeks.

I have just trim my buggy!

My goal is to have a moderate speed and good navigation.

Regarding navigation I saved the points 3 days ago and did all the tests with same points.

The precision differs  from 30 cm to 2,5 meters. It depends on  weather conditions.

 

For driving, speed and heading this are my PID´s :

 

 

 

 

 

Plus:

AHRS_COMP_BETA

0,003

AHRS_RP_P

0,37

AHRS_YAW_P

0,39

Thanks for the link. I'll check it out.

Turnigy also makes a servo reverser and if I remember correctly, it will slow down the servo as well so if you use 3 Y cables, one would split front and back servos, another splits the two fronts, and the other goes to the reverser. The reverser should allow for two servos to run off the one signal.

Here's the link.

@Tom,

I thought about that as well.  Looks like it will be a fun filled weekend :-).

@Mike,

You could easily program an Arduino Pro Mini to reverse the servo direction and proportionalize it to your requirements.
