How to publish Ardupilot information to ROS topic
Started this discussion. Last reply by Chris Anderson Jun 28, 2011. 3 Replies 0 Likes
I'm trying to publish my Ardupilot's state information over serial (usb or xbee) to my computer running a ROS node listening to those serial messages and publishing the corresponding topic.I am…Continue

David Jones replied to Patrick Hammer's discussion ROSSerial compatibility with APM in the group ROS User Group"Our idea is to be able to use collision avoidance algorithms on our planes while still running the ArduPlane software in the ROS enviornment. Currently, we have developed a simulation within ROS to test our collision avoidance algorithms.…"

I could really use a nice diagram to show others how the code works."

Patrick Hammer replied to ljbha007's discussion Flying Android in the group ArduPlane User Group"I agree that the PhoneDrone board is ideal for this.
You should check out ROSJava to do your robot control and ground station interaction. It can run on Android."
Patrick Hammer replied to Garry Qualls's discussion Is this a group effort? in the group ROS User Group"I found I could either hack together a mavlink solution using http://www.ros.org/wiki/mavlink-ros-pkg or integrate http://www.ros.org/wiki/rosserial into APM. I decided I would prefer the latter so I'm currently trying…"
Tom replied to Patrick Hammer's discussion ROSSerial compatibility with APM in the group ROS User Group"Where is ArduinoHardware.h located? I don't have it in my rosserial package, or is it a part of ArduPilotMega code?
Unfortunately I can't tell you where exactly to insert ros.h for your code to compile in ArduinoIDE, the reason being…"
Patrick Hammer replied to Patrick Hammer's discussion ROSSerial compatibility with APM in the group ROS User Group"ArduinoHardware.h includes <HardwareSerial.h>
Not sure the best way to modify this to use FastSerial.h instead."
Patrick Hammer replied to Patrick Hammer's discussion ROSSerial compatibility with APM in the group ROS User Group"Ardupilot Mega compiles beautifully alone.
As soon as I type
#include<ros.h>
I get a ton of errors which I will paste below:

Tom replied to Patrick Hammer's discussion ROSSerial compatibility with APM in the group ROS User Group"Hi Patrick,
check serial_fx.h in ROSSerial Arduino library, make sure this uses FastSerial and not the standard Arduino serial library. I guess that's what's not working. Maybe try including ros.h somewhere later, to make sure FastSerial…"

Tom replied to Patrick Hammer's discussion ROSSerial compatibility with APM in the group ROS User Group"Hi Patrick,
sorry to reply so late, have you already solved your problem? I think I could help, I've been using ROSSerial with APM since it's available (also used avr_bridge before). What exactly is does the compiler say?"

Hey Patrick, I was wondering if you were available to answer a couple questions for me. I am trying to do something very similar to you with ROS and I am wondering what all you have achieved so that I don't have to reinvent the wheel, so to speak. I am going to have a ROS node sending waypoints (as MAVlink messages) to our APM via XBEE serial comm. Also, my ROS node will be listening for GPS coords (as MAVlink messages) that will be sent from the APM to ROS. Have you been able to get row-mavlink-pkg running? Have you figured out the best way to send MAV messages from the APM?
