I setup a ROS vehicle and can control through my keyboard. but the problem is that this vehicle can not navigate to the specified after the route was created.

I run roswtf and got the two errors below.

Found 2 error(s).

ERROR The following nodes should be connected but aren't:
 * /move_base->/move_base (/move_base/global_costmap/footprint)
 * /move_base->/move_base (/move_base/local_costmap/footprint)

ERROR Different number of openni2 sensors found.
 * 0 openni2 sensors found (expected: 1).

Attached files are the tf frame and rosrun rqt_graph rqt_graph
