not sure if we should remove it if cob_twist_controller uses it.
@ipa-fxm-cm: what happens if the controller is run without the distance monitor per default?

[MaChristoph]

@ipa-mdl : If the twist_controller is started without the distance informations then the collision avoidance won't work. The cob_obstacle_distance_moveit node is the "new" one and replaces the "old" cob_obstacle_distance node, since it's computation time is much more efficient. So you might delete the cob_obstacle_distance dependency instead of the cob_obstacle_distance_moveit dep.
