[ERROR] [1389785606.672678540]: Client [/hark_turtlebot_follower] wants topic /HarkSource to have datatype/md5sum [hark_msgs/HarkSource/21a049a3207fea2bd7dd556299ef6e38], but our version has [hark_msgs/HarkSource/967ad288a031a049b6e521f5e5c98ed7]. Dropping connection.

This indicates that nodes in your ROS computation graph have been compiled using different versions of a message type. See also this Q/A. The easiest way to fix this error is recompiling all involved packages using the same version of hark_msgs.
