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…

APM is using Sonar or IR sensors? I found this looking back for the sonar ports.
The processor ADC works very reliably with the Sharp IR sensor and will allow sensors with a 0 - 5vdc output to be used for obstacle detection. Instructions for attaching an IR sensor to the Atmel processor can be found here in the Wiki: http://code.google.com/p/ardurover/wiki/IRSensor If you are using the Sharp medium range (150cm) IR sensor then you should use the following values for the sonar: Sonar_Pin 0, Sonar_Constant 0.63, Sonar_Offset 0, and Sonar_Function 2.
I think I have the IR sensors. I have SRF08 Sonar sensors, which are not the same as those listed in the configuration.
We can use two Sonar/IR? sensors now? Haven't figured out which, or what pins/ports to connect to. I'm not finding the SONAR_etc parm(s).
Thanks,

@saba,
Have you verified in the Radio Calibration that you have movement in the throttle bar from the neutral position when you move the elevator joystick forward? What is the Mode of your transmitter, 1 or 2? The throttle input to the APM (3) should come from the elevator output on the receiver and not the throttle output. Have you verified that this is the way you have it hooked up?

Hello Guys,
anybody knows whether it is possible to use similar hardware to APM? I am talking about the Crius AIOP board which I successfully used with MPNG code (Arducopter port) It has magneto and GPS can be connected as well.
Thanks, Robert.
dear all
i am using the firmware ArduRover_v230_firmware_20130315SS1. output channel1 is steering servo and output channel2 is forward/reverse. in output channel 2 (forward/reverse) if i attach servo motor and check it by giving input from transmitter, after approx 20 attempt there is no output observe????? where as output channel1 is correct all the time.
regards
saba

I see Sonar_ENABLE and SONAR_TYPE on m y1.2.36 AP.
Thanks for the 4x4 reference.

@Alan,
The latest ArduRover2 v2.30 code works well with either MP 1.2.35 or .36.
The Advanced Parameters List in the Configuration Tab has all of the Ardupilot operating parameters including the ArduRover subset. The Advanced Parameters List is in alphabetical order and the SONAR_etc was meant to cover all of the SONAR_XX parameters in the Advanced Parameters List.
As far as the MINDS-i code goes, I used the UAV 4X4 code and bits and pieces out of the Simple Radio Drive and the Advanced Radio Drive.

@Thomas,
I have Mission Planner 1.2.36 mav 1.0. Which AP are you running?
Advanced Parms or Adv Parmeter List?
I'm not seeing Sonar_etc.
Compiled and loaded ArduRover_v230_firmware_20130321SS2\APMrover2

@Thomas,
I've got the latest code compiled, but I'll have to practically take the 'bot apart to program (that's a problem). Which MP versions will it work with? I think you said it was an older, non-available version? Can you send me zip of the MP?
Which MINDSi build? 4x4, 6x6 etc.
Thanks,
Alan KM6VV
@Alan,
Load in the latest code, then call up the Advanced Parameters and take a look in the SONAR_etc area of the parameters. You can set the sonar I/O pins to whatever ADC pin you want.
Presently the APM code will only veer away as it is designed for the Sparkfun AVC at the moment.
I am presently not using any of the MINDS-i code for the AVC. I will use it for the RoboMagellan efforts.
@Paul,
The MINDS-i code is kind of simplistic as it has to fit on an Uno 328. The APM ArduRover2 code is much more sophisticated and getting better with each passing week.
Regards,
TCIII
