Hi, 

When I run the "Joystick example" in Webots it is returned the following error : [joystick] [ERROR] [1319541680.644865286]: Client 
[/joystick] wants topic /joy to have datatype/md5sum 
[joy/Joy/e3ef016fcdf22397038b36036c66f7c8], but our version has 
[sensor_msgs/Joy/5a9ea5f83505693b71e785041e67a8bb]. Dropping connection.

I this that is an ROS error. Can you help me with this situation.

Thanks
