Before Posting an Issue

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.

Hello everyone,I'm trying to design and build an "open source" radar system. The premise is that while we have the hacked Neato and the RoboPeak system, I've not found anything for outdoor use. So…Continue

Hi,Before Pixhawk I used APM 2.5 with LEA6h, wanted to use it also with Pixhawk but was unable to do so. Now I connected Lea6H back to APM and got "no gps" message. Connected USB to Lea6h to see with…Continue

SBUS output on Pixhawk when ?

I understand that the SBUS output on the Pixhawk is NOT currently enabled. Does anyone know when this may happen and will it simply send the Pixhawk output signals  or also passthrough the incoming…Continue

Hello All,

I purchased the APM 2.5, uBlox GPS and 3DR Radio Kit and got it up and running with the Mission Planner. I now want to use this with an AGV that has tank steering. The 2 motor speed controllers I'm using have inputs for a PWM signal with a range 0 to 255 for motor speed and High/Low digital signal for Forward/Reverse.

It has been suggested that using Ailerons Mixing should provide what I need but the only parameter I could find was Elevon_Mixing and setting this to 1 does not seem to do what I want and even if it did the values would be in the wrong range.

I've had a look through the code but I'm finding it difficult to understand so as a temporary measure I tried using a second Arduino to read the outputs from Ch1 and Ch3 using PulseIn() but this doesn't read the values correctly. 

If anybody has got tank steering to work with APMrover2 or anybody can help, it would be greatly appreciated.

Thanks,

Niall

Hello All,

i bought a second hand apm 1, to use with ardurover. looking forward to it, it should arrive in 1-2 weeks. 1 have 1 question. the owner told me i could never use the esc with bec, according to him i always have to take out the red wire from the esc and use a seperate ubec. this because if you plug in the usb without first powering the esc with a battery, there was a chance the esc pulled some power through the usb, causing the bord to blow.

is this correct? are you all using seperate ubecs? i cant find something about it on the forums, thats why i ask:)

thanks in advance!

greets vincent

Hi All,

Well, I have got the ball rolling on building an ArduRover. How about some more build logs to give us ideas concerning building our own rovers! Help with hardware and software builds will be greatly appreciated by all.

Regards,

TCIII

Well if you looking to interface a WII Nunchuck check out

i really need to learn the programing better.  i am going to go look at the arduino site and see what i can learn.  but i dont understand how to get the pulse width to react to the wii nunchuck

Comment by Rich Maynard on September 17, 2012 at 6:04pm

@Bradley

If you have a couple of questions go ahead an post them. Not to put you off though but there are many examples of using PWM on the Arduino site as well the samples and Library examples that come with the Arduino IDE.

ROS can run the connect on the turtlebot! 

It also has stacks to run obstacle avoidance, and blob tracking with a CMU camera.

@Alan,

I am running Window 7 and plan to upgrade to Windows 8. I needed to run Windows 7 to be able to use the Kinect.

Concerning integration of robust obstacle avoidance and goal identification into the APM code, I think that it might not be a good idea due to the complexity of the existing APM code. I plan to let the APM do what it does well: navigate. The Arduino Uno does obstacle avoidance very well and maybe an Arduino Mega can provide goal identification. I am for diversified processing wherever possible as sometimes an all-in-one solution is cumbersome to debug and maintain.

Regards,

TCIII

Would somebody that has alot of experience with programming the arduino help me out with a couple of things for something I am building.  I just have a couple of questions about making two outputs with PWM do what I need it to.

Guys is Anyone running the Ardurover with a minimosd connected via the telemetry port?
