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…

@Austin,
It sounds like that you might have not given the APM time to format the on board Flash EEPROM. You might want to reload the latest firmware then use the CLI to do a soft reset then a hard reset and then go have a soda while the Flahs EEPROM is formatted. After that you should not get the SD formatting failure message. Mine acted the same way until I let the Flash EEPROM format completely.

Thanks! I downloaded the new firmware and the board connects fine and everything, but I ran in to some issues which most likely have to do with the board itself. when I went to the terminal to calibrate the radio and adjust mode toggles, I got an error saying that it failed to boot mpu6000 numerous time and then it panicked or something like that. There also was an error at the top regarding something about a flash card. I would give the exact error, but I don't have access to the board right now. I basically couldn't get it to write any waypoints and the throttle in manual didn't work, along with me not being able to see any sensor data. I have a back-up APM 1.4, but the Spectrum 6-channel radio system doesn't seem to cooperate with that board =(.
Hi Austin,
i would try the new version.
2.4 has a lot of enhancements and should work way better although the release is not fully tested yet.
look here for more information.

Is firmware 2.40 better than the 2.30a? I got my rover to work for a period of time, but now when I put it into Auto mode the throttle doesn't initiate even though it works in manual mode. I am n ot sure if this has something to do with the firmware or if it is a hardware malfunction. so I am not sure now if I should try to troubleshoot this more or try the new firmware.
@saba,
Glad you were able to resolve and correct your problem with your rover.

Dear TJC
Thanks a lot. it was my receiver connection problem. thanks to resolve.

@Saba,
The ArduRover2 code uses APM output pin 3 for the throttle not output pin 2. This assumes that you are not using the ArduRover code in the skid steering mode.
Please refer to this ArduRover wiring diagram: http://code.google.com/p/ardurover/wiki/ArduRover2Setup for the correct connects between the APM and your motor controller.

Dear TJC
i am sorry. my JP1 is not connected. no issue of output power. only the output pin 2 (Forward/Reverse) has problem. because if i connect output pin 1( steering) to Forward/Reverse Motor of vehicle, it works fine. so pl highlight the part of code that is giving output servo command. or any body else facing the problem. further if the vehicle is not connected and i just check output on my servo motor, the motor stuck after 10 to 15 times movement. whereas no problem with output 1 (steering servo)

@Saba,
If you are powering the APM servo output with its own power supply, then you should remove J1 if you are powering the APM with the USB connector. Look at this Wiki page on powering the APM2.5: http://code.google.com/p/ardupilot-mega/wiki/APM25Power

TCIII
dear TJC
My J1 is connected and power of servo is from a battery of 5v and receiver is getting power from APM 2.5. APM 2.5 is getting power from laptop USB port.no ESC is here. i am using Mission Planner. What is PM in your reply.
regards
