Create powers off after minimal.launch

edit

I just got an iRobot iCreate base and I've followed the instructions given in ROS Tutorials to setup the turtlebot pc and the workstation. I could successfully ssh into username @ turtlebot through workstation so I'm assuming that is all good. I had an issue with create not able to detect the usb cable which I solved using the detailed answer given for [question] (http:// answers.ros.org/question/46790/failed-to-open-port-devttyusb0/) at ros answers. This solved the problem of "Failed to open port / dev / ttyUSB0" that I was facing before.

Now the next step would be to ssh into the turtlebot (which I've done) and use roslaunch turtlebot_bringup minimal.launch to do whatever the command does (I've no idea what to expect upon launch). But apparently something's amiss since the create base chirps and then powers down after showing [kinect_breaker_enabler-5] process has finished cleanly as output and the log file location (see output below), but I dont see a prompt. I checked the battery and that's charged so that's not the problem. Following is the terminal output.
