 # Voronoi HSI (Human-Swarm Interaction)
 
-Multi robot coverage control in non-convex environments using ROS.
+Multi **robot coverage control** in non-convex environments using **ROS**.
 
-This is a ROS implementation of a multi-robot coverage control strategy based in [1] and [2] to address coverage in non-convex
-environments and adapt to performance variations. It also has a plugin software that allows humans to interact with the robotic
-swarm, influencing their coverage task.

+This is a ROS implementation of a multi-robot coverage control strategy based in [[1]](http://journals.sagepub.com/doi/full/10.1177/0278364913507324) and [[2]](http://sites.bu.edu/msl/files/2014/10/PiersonFigueiredoPimentaSchwagerICRA15.pdf) to address coverage in non-convex environments and adapt to performance variations.

+It also has a add-on software that allows humans to interact with the robotic swarm, influencing their coverage task using Unity: [Voronoi Unity Teleoperation](https://github.com/lucascoelhof/VoronoiUnityTeleoperation)
 
 # Getting started
+
 Dependencies:
-* Stage
-* matplotlib
 
-Download the code, compile it and run using:
+* [Stage](http://wiki.ros.org/stage)
+* [matplotlib](https://matplotlib.org/)
+* [ar_track_alvar](http://wiki.ros.org/ar_track_alvar)
+* [gctronic/epuck_driver_cpp](https://github.com/gctronic/epuck_driver_cpp)
+
+Download the code, place it on your catkin environment, compile it using ``catkin_make`` and run using:
+
 ```
 roslaunch voronoi_hsi voronoi_8_with_app.launch
 ```
 
-We've also developed experiment using the e-puck robot and a driver available at [gctronic/epuck_driver_cpp
-](https://github.com/gctronic/epuck_driver_cpp).
+If you want to use real robots (epucks) instead of simulating it on Stage, you will need the driver [gctronic/epuck_driver_cpp](https://github.com/gctronic/epuck_driver_cpp). Run it using:
 
+```
+roslaunch voronoi_hsi voronoi_8_with_app.launch real_robot:=true
+```
