The complete TurtleBot 2 includes a Kobuki base, Microsoft XBOX Kinect, ROS compatible netbook, and factory calibrated gyro.
There are several kits avaliable to create a Turtlebot. Check out the distributors’ website to find out more.
The TurtleBot 2e is a new revision of the TurtleBot primarily defined by replacing the netbook with a single board computer such as the 96 Boards CE computer, the DB410c.
You can build a Turtlebot from scratch by purchasing the parts such as netbook, Kinect, and Kobuki separately and following the documentation.
