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.

Download and Install
Dependencies
Install octomap_ros and rviz plugins.
sudo apt-get install ros-indigo-octomap*
from source
Please download the source code from:
git clone https://github.com/RobustFieldAutonomyLab/turtlebot_exploration_3d.git
then
catkin_make
binary form
sudo apt-get update
sudo apt-get install ros-indigo-turtlebot-exploration-3d
Setup
Please follow the turtlebot network configuration to setup network between turtlebot and remote PC.
Run
From turtlebot laptop
$ roslaunch turtlebot_exploration_3d minimal_explo.launch $ roslaunch turtlebot_exploration_3d turtlebot_gmapping.launch $ rosrun turtlebot_exploration_3d turtlebot_exploration_3d
From Remote PC
roslaunch turtlebot_exploration_3d exploration_rviz.launch
Topics
Subscribed Topics
tf (tf/StampedTransform)- looking for transformation between /map and /camera_rgb_frame
- point cloud from Kinect sensor, can remap to a different topic, however have to be similar to Kinect. Otherwise need to update the sensor model in the source code.
Published Topics
octomap_3d (octomap_msgs/Octomap)- The octomap generated by this node, published only after each observation.
