Hi.

I am using ros_control from the debs with ROS Indigo. With the gazebo_ros_demo, I get the following messages:

...
[ERROR] [1406959851.284469964, 0.218000000]: No valid hardware interface element found in joint 'joint1'.
[ERROR] [1406959851.284937831, 0.218000000]: Failed to load joints for transmission 'tran1'.
[ERROR] [1406959851.285297862, 0.218000000]: No valid hardware interface element found in joint 'joint2'.
[ERROR] [1406959851.285833893, 0.218000000]: Failed to load joints for transmission 'tran2'.
...

The version from the debs may be broken or the demo package should be adapted.

@k-okada fixed this https://github.com/ros-simulation/gazebo_ros_demos/pull/4

[trainman419]

the documentation still references the old syntax for this: http://gazebosim.org/tutorials/?tut=ros_control

Thanks for the heads-up. I'll propose a fix.

I just opened a pull request to fix the gazebo tutorial:
