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").

Hi, i am looking to build a new rover, but i need some advice on the chassis. I like the 4wd chassis/tank look and prefer it over the crawler/rc look.are those any good though? most people recommend crawlers.I am looking to get something from banggood, any advice will be highly appreciated. thanks
Read more…Hi all, I have a skid steer robot using a pixhawk cube, one 1x15 roboclaw motor controller and a dagu wild thumper 4 wheel chassis. I have skid steering working so far, testing motor c and motor d tests works as described and the vehicle can be controlled in manual mode. However, upon using any mode other than manual mode the rover wants to shake and pivot on the spot, and it seems the steering PID controller oscillates and these oscillations get larger. i have tried everything but it is still…
Read more…Hi,I have converted a Traxxas X-Maxx into a rover using the Pixhawk Cube 2 controller kit with a Here GNSS.I swapped out the original X-Maxx remote controller for an X6R receiver and Taranis QX7 radio.latest version of ArduRover firmware installed as of 8/11/18. The rover has an EZRun Max6 ESC. The problem now is the ESC control over the transition into reverse. The ESC is currently set to it's Running Mode Option 2: "Forward/Reverse with Break", AKA the "Double Click Method".What this mode…
Read more…Hi all.I know this is an Adurover group, but Thought I would reach out and try my odds for some help as I'm perplexed by this problem. I have a Traxxas X-Maxx set up with a Pixhawk Cube 2.1 and the Here GPS. I'm using a Tarranis X7 remote controller and a X8R Sbus Receiver. I'm using QGroundControl with the latest, Pixhawk 1.8.0 Firmware with the Generic Rover airframe profile installed. As instructed, I have Steering servo wired into Main 2 and Throttle ESC wired into Main 4. Sensors are…

Quick question. Is this the sonar sensor you guys are using?

@Tom - me too, hopefully next time. I keep meaning to be able to head to Dark Horse after these things and somehow always get thwarted. :D Anyway once again Congrats on an awesome achievement, Tom!
Tom, Tridge, and everyone, congratulations!!! That was an awesome showing. And, great to finally meet you in person, Tom! --Michael
It was a great day for Team ArduRover and Tom was absolutely beaming. He's got a long drive back to Florida to savor the victory, but the lesson here was that hard work pays off. Huge thanks to Tridge, Tom and everyone else for bringing this code up to contest-winning quality over the past few months. Next year, we can add vision, Lidar, DGPS and more and become unbeatable.
Huge congratulations to Tom Coyle for winning the Sparkfun mid-size Rover category at Sparkfun AVC on the weekend! Tom has put a massive amount of effort into testing the APM Rover code, and it really paid off for him. I haven't yet found a video of his run, but from what I've heard his rover managed to get through the barrells, through the hoop and over the ramp to produce a winning score.
Hopefully when Tom is back home (it's a long drive!) he will write up the full story.
Cheers, Tridge
Thanks for the info. I'll upload the latest firmware and give it a try.

@Mike,
I forgot to mention that there is a simple workaround for the bug. Just change the value to something else first - for example, change it to 0.1, write the parameter change, then change it to 0.0. It will then work.
Cheers, Tridge
@Mike,
It's a bug which I fixed a few days ago. I plan on releasing a new rover version soon with the fix, but meanwhile you could load the 'latest' version from firmware.diydrones.com and that has the fix.
Cheers, Tridge
@ Tom or John,
I'm trying to set the Steer "D" values to zero but for some reason, the APM is not accepting the settings and they go back to 0.2 if I disconnect and reconnect to the APM. If I write the parameters and then do an immediate read, the values are correct but if I do a disconnect and reconnect, the values are back to their default.
Am I missing something or is this a bug?
...Mike
@MV,
Unfortunately I did not save my parameters, but I believe they are the default parameters except the heading2steer and servo2steer, the "D" I changed to zero. I have some other experience with tuning and it seems that the D parameter is not often needed. I watched your video, your rover is running great. I look forward to hearing and seeing more.
@Mikel-Ange,
I think you are right, we need to build drones/rovers/robots that do real work. This is my real motivation behind the hobby.
