Hey there,

Others have had success with this: http://stackoverflow.com/questions/15...

Hello,

I would suggest creating a string and outputing that to the ROS computer, as shown here: http://wiki.ros.org/rosserial_arduino...

That way, all you have to do on the computer side is subscribe to that topic. On the Arduino side, put whatever you want into the hello char array.

Let me know if that works for you :)

Hello all,

I have recorded a fairly long rosbag file (~8.5Mb).

However, when I try to play it I get:

[FATAL] [1441050519.918179421]: size of the compressed data exceeds *destLen

Here is rosbag info:

The file itself is here , though it needs custom message type from: https://github.com/ibaranov-cp/batmon

Hello there,

The main reference for all things Husky related is here: http://wiki.ros.org/Robots/Husky

Specifically, you want to look at this page: http://wiki.ros.org/husky_navigation/...

Which is the first tutorial in Section 3.1 Navigation. That section should get you to doing mapping and navigation in simulation.

The source code for all the examples is also here: https://github.com/husky/husky

Specifically, the code from the move base example above is here: https://github.com/husky/husky/blob/i...

Best wishes, Ilia B.

Of course, I meant simply as a starting point to use as a model.

Thanks for letting me know, I will try it out in the coming weeks and answer here. Cheers!

Thanks, that looks like a great place to start!

Hello,

Best to learn by example.

Take a look at the code here: https://github.com/turtlebot/turtlebo...

You are essentially looking to do the opposite, avoid the obstacles instead of following them.

Hey there,

Please check here: http://wiki.ros.org/ROS/Tutorials

Probably you are looking for: Writing a Simple Service and Client (C++)

Hello,

To start with, have you checked out this package: http://wiki.ros.org/mjpeg_server

In general terms, if you can access the web stream in OpenCV, you can write a python module to re-publish it as a rostopic.

Best wishes, Ilia

Hello all,

With the TK1 being a fairly well supported ROS platform, I was wondering how well the USB 3.0 port is supported? Presumably, I would be using 14.04 and Indigo to get the ball rolling.

Specifically, how difficult should it be to get the Kinect V2 running on the TK1? Austin might know about this.

Hopefully, we can get cheaper "starter" ROS platforms out there if this works.

packages.willowgarage.com is back to life!

You may notice it redirects to an amazon S3 instance, but all existing links should work correctly.

Sorry for the outage.

(Clearpath PR2 support Team :) )

Excellent! Thanks

That link text is broken :(

Hey, Your github code seems deleted. Any chance you would put it back?
