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:

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…

@Thomas,
I have Uno R2 and R3s. I should look at the MINDS-I (again). But first I need to see the APM2 do something!
I received the missing axle bolts for my 'bot, so after some more fitting and trimming, maybe I can get my 'bot to move! Then I can try out the APM2.

@Chris,
Thanks for you confidence in us. Much appreciated. We will do the best we can to take JLN's lead and refine and update the ArduRover firmware.

@Alan,
The MINDS-i processor is a Uno R2. There is an R3 version too. The Atmel 328 can be purchased as a mini and might be more cost effective than a PIC.
Just a thought.

@Thomas,
I don't have the minds-I processor, but I'm thinking of doing something similar. I want to use SRF08 sonars (an array of 6), and possibly interleave them with IR sensors. these would be handled by a PIC, and read by a ROS node for behaviors.
ROS could also process the LiDAR signals.

Great work, Tom. Looks like time to upgrade your badge from Moderator to Developer! Linus, I've upgraded you, too.
Hi All,
Some good news. Linus and I have been looking at JLN's code and Linus has come up with some improvements in the IR sensor processing code. Also we plan on incorporating u4eake's processing suggestions that can be found in the later pages of the JLN's ArduRover discussion.
On another note, I have managed to proof out that the MINDS-i Uno obstacle avoidance code that uses PING and IR sensors can be modified to process external steering and drive PWM signals to steer my rover when it is not avoiding obstacles. This means that I will probably be able to use the APM for waypoint navigation and the Uno for obstacle avoidance.

Hi All,
As you know I have been working on using a Traxxas E-Maxxs chassis for my ArduRover project. If you are contemplating going the same route, I must warn you that due to the speed of the stock E-Maxxs and the fussiness of the Mamba Monster ESC you might want to consider using a Traxxas or other brushed motor chassis for you rover.
Just a thought.

@Doug,
Take a look at this Forum thread: http://www.diydrones.com/forum/topics/powering-the-ardupilot-board-1
Hopefull one of the 35 response might give you some insight into powering the APM 2.5. Also take a look at these instructions in the ArduPlane wiki: http://code.google.com/p/ardupilot-mega/wiki/APM2RC

I got an APM 2.5 with plastic case for my RC boat. While operating in the boat, the 5V pins must be jumpered to get power from the receiver. But for programming, the board gets its power from the USB cable. Since the jumper is already installed and the case is closed, what is the effect of plugging in the USB cable? I don't feel comfortable using both power sources, unless the board has circuitry that keeps the two separate. Does anyone know?
Thanks. DC
@Rich,
You have some vaild points that maybe our members should want to consider and maybe implement.
I like the Comment Wall because its a quick way to maybe get a quick response to a question that might get buried in the Discussion Forum. I believe that our Discussion Forum is the appropriate place for ArduRover Build Logs as they may not be of interest to the general DIY Drones Membership. I feel that this User Group is a special place dedicated specifically to the ArduRover and not to just general unmanded ground vehicles which is a separate Forum.
Comments?
