I assume you're using electric (otherwise please update your question with the necessary information)?

Since electric, the "joy" msg is in sensor_msgs, so you need to change from joystick.msg import joy into:

  from sensor_msgs.msg import joy

in the affected code.

For anyone using hydro joy ought to be capitalized: from sensor_msgs.msg import Joy

before all thanks for answer, sorry I forgot put some information, I'm using electric in ubuntu 11.04, and I'm tryin to do the remote controll whit and ipad to the pioneer2, when I changed the line of the code i had other problem, it shows "from sensor_msgs.msg import joy ImportError: cannot import name joy"

and just a line before that error, appears "ERROR: cannot launch node of type [teleop_base/teleop_base]: Cannot locate node of type [teleop_base] in package [teleop_base]"

does it maybe appear because it needs others files in teleop_base directory? I downloaded the teleop_base from "ubuntu software center" and used rosmake to make the teleop_base

thanks for all
