I've been following the turtlebot tutorial (http://www.ros.org/wiki/Robots/TurtleBot) I am stuck on 5.TurtleBot Odometry and Gyro Calibration

When I run
$ roslaunch turtlebot_calibration calibrate.launch,
I get the following output, and the final message "Still waiting for scan" repeats forever.

Any suggestions?
I am using the full kit that comes with everything (irobot, kinect, eeepc, etc).


turtlebot@turtlepc:~$ roslaunch turtlebot_calibration calibrate.launch

It sounds like your TurtleBot software on your TurtleBot might not be up to date:

sudo apt-get update


sudo apt-get install ros-diamondback-turtlebot-robot

Thanks! That helped a bit. It now gets past the previous error, and the robot starts rotating. However, before completing a full turn, it stops and the wrench icon on the dashboard becomes red. Its says Power System: Error.
