> Hi,
>
> I'm a total ROS newbie but have been reading the ROS wiki for hours now. I
> have a mobile platform with differential drive, odometry and sonars and
> would like to use ROS to make it autonomous (i.e. build a grid map using the
> sonars and odometry and maybe a simple exploration strategy, then navigate
> on that map). Is there a simple tutorial like "how to use ROS on your
> robot"? I haven't found anything like this and find this all very confusing
