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.

About My EcoRover and due to the fact the solar rover is a specific discussion I think it is better to have a dedicated threads.
My EcoRover
Now my Rover has the solar option.
It is a modular concept and easy to change. So the panel can easily be removed.
The solar panel feeds a 2S LiPo battery with 2 X 6V and 0.940 amp.
More details soon.
Thanks Chris.
I haven't yet added the rover brain to my truck, but I'm wondering if the code could handle a couple of interesting features:
1) front and rear wheel steering, in case extra-tight turns or crab-walking is necessary for manoeuvres,
2) DIG (mostly rear wheel), which is the ability to lock the rear wheels from turning, making turns ultra tight.
Also with DIGs, they sometimes include a half-way setting which disengages the rear drive shafts giving front-wheel-drive instead of 4wd, but I'm not sure that would be beneficial or relevant.
Just curious, thanks for the awesome work!
And you'll probably want two, so your rover can turn the right way away from obstacles
We use the Maxbotix 1240
Just realized that's an IR sensor. Which ones are you using?
Oh, and are you using two at the moment or just one? SparkFun has a sale going on for a few more days so I wanted to pick one or two up while I can.
Quick question. Is this the sonar sensor you guys are using?

Hi All,
Tridge and I have made exceptional progress this last weekend with validation of the L1 version of the ArduRover2 code. There are three critical tuning parameters in the L1 code: NAVL1_PERIOD, TURNING_CIRCLE and TURN_MAX_G.
I measured the turning radius of my Slash rover and found it to be 1.3m. We started testing with the NAVL1_PERIOD at 8 and the TURN_MAX_G at 4. With the NAVL1_PERIOD at 8 there was not enough turn authority and I ended up with the value of that parameter at between 3 - 4. At 3 the rover negotiated tight turns (chicanes) very well, but tended to hunt on the straightaways. At 4 there was no straightaway hunting, but the tight turn navigation was not optimal. I also upped the TURN_MAX_G value to 10 and left it there for the remainder of the testing.
I suspect that the L1 code can be modified to be able to negotiate tight turns, but not hunt on the straightaways. I think that we are very close to being able to release a beta version of the code in the next few weeks.
I also liked the fact that the L1 code made nice sweeping turns around corners compared to the Non-L1 code which tended to turn in short segments around a curve.
More to come.
Regards,
