I'm trying to run the tutorial "Writing Teleoperation Node for a Linux
supported Joystick" (http://www.ros.org/wiki/joy/Tutorials/WritingTeleopNode)
but, when I launch it, this errors occurs:

[ERROR] [1319554411.613621554]: Client [/teleop_nao] wants topic /joy to
have datatype/md5sum [joy/Joy/e3ef016fcdf22397038b36036c66f7c8], but our
version has [sensor_msgs/Joy/5a9ea5f83505693b71e785041e67a8bb]. Dropping

Any ideas on how to fix the problem?

My computer is running Ubuntu 10.04 and I'm using ROS electric.
