Hi at all
I'm doing the gripper tutorial
"http://www.ros.org/wiki/pr2_controllers/Tutorials/Moving%20the%20gripper"
this is my launch file
<launch>
<node name="gripper_action" pkg="simple_gripper" type="gripper_action" />
</launch>
I've this error
"ERROR: cannot launch node of type [simple_gripper/gripper_action]: can't locate node [gripper_action] in package [simple_gripper]"


Please can you correct my launch file

The launch file looks fine. It's hard to say what's wrong, but at a guess I would say simple_gripper hasn't built correctly.

Try rebuilding with "rosmake simple_gripper"
