Hi everyone!<div><br></div><div>Here at the lab we use Roomba robots with Eee PCs on top. The Eee PCs have a single core Intel Atom processor, not the quickest thing around! Each Roomba is also equiped with an Hokuyo laser. </div>
<div><br></div><div>So I&#39;ve recently been playing around with the ROS nav stack. I&#39;ve tried to make it as simple as possible according to the various tutorials and mailing list msgs I&#39;ve came across with, however I&#39;m always getting a warning that it is running below the 20Hz frequency. It is also noticeable the fact that the robot does not move properly, and eventually crashes.</div>
<div><br></div><div>Previously I experimented the same setup on an Erratic robot with a Celeron, and although it was taking pretty much all of the processor to run the nav stack, it was able to move pretty well around the lab according to the commands I was issuing from rviz.</div>
<div><br></div><div>So my question is, how can I use the nav stack in its simplest form, in order to have it running smoothly on the Eee PCs?</div><div><br></div><div>I&#39;m attaching the .yaml files I&#39;m using for configuring the nav stack.</div>
<div><br></div><div>Thanks in advance!</div><div><br></div><div>Gonçalo Cabrita</div><div><br></div><div><br></div>
