Re: [ros-users] Nav Stack with nonholonomic robots

Eitan,

I compiled the pose_follower and loaded it instead of the
base_local_planner. But still I am missing something. rviz does not show
a global plan any more. The robot moves, but backwards and the log gives
me the "Not legal" error from pose_follower.cpp line 169.

My launch files look like this and I think by kicking out the
base_local_planner I damaged something vital.
