Hi,<br><br>I&#39;m also still learning to use ROS with the higher goal of getting an Arduino system work with it. I&#39;m experiencing with ROS using a Lego NXT, I&#39;d recommend using it to you as well. There are a quite nice stack for it and after you managed to get do all you need you&#39;ll just have to take a look at how the guys made the &quot;drivers&quot;. <br>
<br>For &quot;Hello ROS&quot; there is a tutorial at <a href="http://www.ros.org/wiki/ROS/StartGuide">http://www.ros.org/wiki/ROS/StartGuide</a> or for the NXT at <a href="http://www.ros.org/wiki/nxt">http://www.ros.org/wiki/nxt</a> .<br>
<br>Good luck with them :)<br><br>Regards,<br>Bence Magyar<br><br><div class="gmail_quote">2010/11/10 mark <span dir="ltr">&lt;<a href="mailto:mark@mxnet.f2s.com">mark@mxnet.f2s.com</a>&gt;</span><br><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">

<span lang="en-gb"><font face="Arial" size="2">Hi Group,<br>
<br>
Just looking for some advise here on how I can best use ROS<br>
</font></span>
<p></p>
<p><span lang="en-gb"><font face="Arial" size="2">Where I am now:</font></span>
</p>
<p><span lang="en-gb">        <font face="Arial" size="2">At the
moment I&#39;ve hand crafted s/w. It&#39;s broken up into two main parts - the
lower level stuff (Running on a SH7032 chip) to control the robot&#39;s
hardware and communicate with the host system, all reactive behaviours
(avoid, escape et al). And the Host system higher level functions
(Navigation, Path planning, Mapping etc). More info at </font></span><a href="http://toeminator.com/Toeminator/ToeminatorIndex.htm" target="_blank"><span lang="en-gb"><u><font color="#0000ff" face="Arial" size="2">http://toeminator.com/Toeminator/ToeminatorIndex.htm</font></u></span></a><span lang="en-gb"></span></p>

<p><span lang="en-gb"><font face="Arial" size="2">Wants:</font></span>
<br>
<span lang="en-gb">        <font face="Arial" size="2">I&#39;m looking to
experiment with the ROS, the point I&#39;d like to get to is have a visual
UI of my robots environment, ideally using SLAM (I&#39;m not sure what
modules there are for sonar data?) and replicate the host side of the
system. To that end I wondered if anyone could give me some starting
points. I&#39;ve had a quick look at the tutorials and loaded the s/w onto
a virtual box.</font></span></p>
<p><span lang="en-gb"><font face="Arial" size="2">I would guess my
simplest starting point would be to develop something that would sit
between the current server (Sends/receives data to/from the robot) and
the ROS. Which is where I get somewhat lost. What do I need to develop?
Is there a common ROS message format? What packages/modules should I be
looking to use to get something tangible up and running? Is there a
&quot;Hello ROS&quot; starting point I could usefully use. Or am I barking up the
completely wrong tree?</font></span></p>
<p><span lang="en-gb"><font face="Arial" size="2">Many Thanks</font></span>
