Hi,

It seems that navfn does not consider the size of the robot and the goal orientation when planning a path.

I'm using ROS hydro on Ubuntu 12.04, the robot is 1.3 m wide and 1.6m long and navfn plans a path trough a tight passage whose size is 1m.

In a second example the goal is 0.5m from the wall and parallel to the wall: the robot cannot reach this position since is width is 1.3m (0.65 > 0.5m) but navfn plans anyway a trajectory.

I modified the inflation radius parameter from 0.5 m to 1 m but nothing apparently change. How can avoid this behaviour?

Thanks.
