I'm trying to run the Bringup Tutorial for Turtlebot Groovy. But I always get

[WARN] [WallTime: 1368713745.246504] Create : robot not connected yet, sci not available

I have recently upgraded ROS to Groovy and I'm using a Gateway computer for Turtlebot. I have done all the tutorials for Installation and Network Setup. The Turtlebot is plugged in and the lights are on.

[WARN] [WallTime: 1368713742.227517] Create : robot not connected yet, sci not available
    [WARN] [WallTime: 1368713744.380423] Battery : unable to check laptop battery info [/proc/acpi/battery/BAT0 does not exist]

    log file: /home/turtle2/.ros/log/07609262-be33-11e2-8571-d0df9aaae785/kinect_breaker_enabler-6*.log

At this point, the Base beeps and goes off. The iRobot light keeps on. Then I turn the base back on:

[WARN] [WallTime: 1368713868.243731] Failed to read sensor package. 5 retries left.
[ERROR] [WallTime: 1368713868.498948] Failed to contact device with error: [Distance, angle displacement too big, invalid readings from robot. Distance: 29.73, Angle: 58.26]. Please check that the Create is powered on and that the connector is plugged into the Create.
[ERROR] [WallTime: 1368713878.887388] Failed to contact device with error: [Error reading from SCI port. No data.]. Please check that the Create is powered on and that the connector is plugged into the Create.

Any ideas?

I have the same problem and I'm very confused because it wasn't happening before.

I modified minimal.launch and I don't seem to get the error anymore (after 5 minutes, so I'm not sure that's the fix, but hopefully it is). So I changed robot/name for robot_name and robot/type for robot_type.

Nevermind... it occurred again, but I fixed it by recharging the battery. I think it was almost empty, even though the dashboard was indicating that it was full and despite the fact that I had let the robot charge for a very long time.

If you're using a non-standard laptop you will need to verify that the device ports are valid in the launch files. It looks like /proc/acpi/battery/BAT0 is invalid. And it is probably looking for the USB port on the wrong device as well.

I'm a newbie to Create. I've heard that the battery could be a problem. I'm currently charging to make sure that's eliminated. But how would I change the ../battery/BAT0 files to include a non-standard laptop?. Could you also please elaborate how I would modify the launch files (minimal.launch?) to include the correct ports

You should start a new question for this...info you can find at http://wiki.ros.org/turtlebot/Tutorials/hydro/Netbook%20Battery%20Setup.
