Hi guys! actually, the robot counts with two fixed standard rear wheels and two steerable standard front wheels, the front wheels are the motorized driving and steering wheels. So basically it is an Ackermann type steering.

Hi everyone! I am working on a non holonomic, non differential drive robot, and I was wondering if there are already plans to extend the navigation stack to this kind of robots?

Hi! Could you solve this problem? I am having the same thing.... ROS Hydro on Ubuntu 12.10. Thanks!

what errors are you getting?

Hi everyone!

I am trying to work with ROS on an Intel Galileo Board. I followed the instructions as explained here: http://wiki.ros.org/IntelGalileo/Inte... . I did manage to compile and everything went ok and the board bootet. The problem is when trying to login. It will not accept the user "root" either with empty pwd or with "root" as pwd. Does anybody has an idea why? I also tried reseting the root pwd using an arduino sketch but I cannot connect to USB port of the board. I am using ROS Hydro, host computer has Ubuntu 12.10 installed and the version of Yocto Linux image is v1.0.0

Thanks in advance!

Hi!

I am trying to get the Beagle-ros working on my beaglebone black but I haven't been succesful so far. I have worked with ROS before, but I have never used openembedded or cross-compiled anything before, so I am pretty new to that. I followed the steps on the wiki and I have succesfully installed beagle-ros on my beaglebone. I can run ros without a problem. I have also installed the beginner-tutorials and it is working. The issues start when I go to the next step: Installing recipes. First, I can't find the "sources" directory on Angstrom. And also no meta-ros directory is there. So I went on and clone the bitbake, openembedded-core, meta-openembedded and meta-ros repositories. But I don't know how to go on from there. I am using the Angstrom version from 2013.09.04, which is supposed to be the last one.

Any help will be apreciated! Thanks in advance

Thanks for your comment Boris. I checked my CMakeLists.txt file and noticed that I didn't have rosbuild_init() in it. I added it and now it works.

Hi everyone!

I am having a bit of a problem with my code. I want to write a simple node but I am getting the error "undefined reference to ros::init(....)"

My code looks somethins like this:

class Bridge
{
private:
    ros::NodeHandle nh_;

};

int main(int argc, char** argv) {

    ros::init(argc, argv, "bridge");
    Bridge bridge;
};

Any idea why is this happening?

Thanks in advance
