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.

GPS precision on pixhawk ?

Started by heliboy. Last reply by RoboBill on Wednesday. 3 Replies

Perhaps only the developers can answer this question. What is the resolution of the GPS2 input on the PIXHAWK ? If we had a decimeter precision GPS would the Pixhawk correctly use the higher…Continue

I read somewhere the official 2.46 had track steering problems. I understand the current beta fixes that issue. Many thanks to all developers. But the current beta now seems to have disabled the…Continue

@Tearig,

Looks like a great start!

Getting my rover going, I will have time to dive deeper into the code now and see what is ailing the skid steer options and other peripheral problems, looking forward to playing skid steer for a while...

@RoboBill,

At one time the ArduRover2 Developers considered using a PX4flow module to implement a speed and direction flow function, but we have not moved ahead with the project at this time.

@TCIII

Thanks for the update. Blazing a SLAM trail is way over my head. Another possibility is the PX4Flow. If I mounted it a few inches off the ground facing down, could it measure speed and direction? Could it be used with the mission planner?

Thanks

RoboBill

@RoboBill,

I think that the original intent of the LIDAR-Lite was for range finding, but you might be able to use it as input for a SLAM function.

@Raimo,

When I tested the rangefinder function in ArduRover2 v2.47 beta 1, I was not successful and had issues that I have passed on to Tridge in the form of tlogs and data flash logs. It could be I am doing something incorrectly when setting up the rangefinder parameters. I am sure that Tridge will be able to tell from the tlogs and data flash logs.

Regarding the Lidar-Lite... is this just for obstacle avoidance or can I guide my rover to waypoints that are X and Y away from a corner?

@Raimo,

Tridge has indicated that he has gotten the rangefinder (sonar) function to work correctly. I have yet to do so and plan to test the function again tomorrow with the latest v 2.47 beta 1 firmware and send Tridge a tlog of my testing results if I am not successful.

Regards,

Is the sonar aka range-finder function working now?

Hi All,

Today I verified that the skid (differential) steering function in ArduRover2 v2.47 beta 1 performs correctly. The latest beta can be found here: Latest firmware
