Re: [ros-users] gmapping errors

Ya, I did that.
It may have something to do with the p2os_teleop package that I am
using -- could they be interfering? I installed the teleop package
after gmapping worked for me last Friday... so that's probably it...
any ideas on interference between the two?
Thanks
Rishi
