Removing some launch files that we don't need anymore
Porting the ground removal stuff away from PointCloud to PointCloud2. Still needs testing though.
Remove deprecated API usage
eigen updates
port to eigen3 and remove deprecated use of message size
Unreal, the code actually depended on reading the parameters every cycle to work because it reset the value of z_threshold_ which got transformed to a different frame every cycle
Removing reading of parameters from the cloud callback
Changing in all three files instead of just one for empty cloud... this package is a mess... really should switch to new pcl stufff
Empty clouds are sometimes expected and should be passed on... not errored on and dropped
Copying pr2_navigation from staging area to stacks section of the repoistory
