I use ROS indigo, I have followed the following steps for create base in turtlebot

export TURTLEBOT_BASE=create export TURTLEBOT_STACKS=circles export TURTLEBOT_3D_SENSOR=kinect

But still whenever I enter the roslaunch turtlebot_bringup minimal.launch

it shows the error

"Failed to open port /dev/kobuki. Please make sure the Create cable is plugged into the computer. "

Please help

Looks like there was an update in the turtlebot code: https://github.com/turtlebot/turtlebot/pull/112/files

Try setting TURTLEBOT_SERIAL_PORT to the device your create is listening to (probably /dev/ttyUSB0). I updated the hydro wiki page to reflect this.

The problem still persists with no change. is this specific to turtlebot in ros indigo ?

Hydro and indigo should be the same in this regard. Next step would be to check that there isn't a bug in the python create driver code. Add some printf's to make sure this parameter is getting through.
