What is it ?

This is an ROS implementation of infomation-theoretic exploration using turtlebot with a RGBD camera (e.g. Kinect). It is designed for autonomous mapping of indoor office-like environments (flat terrain). All the computation is performed on the turtlebot laptop and intermediate results can be viewed from remote PC. The output consist of both 2D and 3D Octomap (.ot) file and saved on the turtlebot laptop.
