Matt, Stageros is meant to be run instead of a robot base when testing higher-level things such as navigation. I'd think if you are using stageros, you shouldn't need to run p2os at the same time. Are you actually connected to a Pioneer base via serial while trying to launch p2os with stageros? If not, then it is entirely reasonable for the driver to fail (but a better error message might be nice). - Eric On Tue, Oct 26, 2010 at 6:21 PM, Matt Bergsma wrote: > In pretty much a clean install of cturtle, with p2os and stageros > installed.
