This is the public repository for the code of the paper "Optimized Coverage Planning for UV Surface Disinfection", ICRA 2021.

Requires Python 3.x (3.7+ recommended) and an OpenGL 4.1-compatible graphics card for visibility calculations.
This program depends on two pieces of software distributed under separate liceses: Gurobi and LKH-3.0.6. To install:
-
Install the Python libraries contained in requirements.txt (pip install -r requirements.txt)
-
To get gurobi up and running on your system,you can follow the instructions here (for academic licenses) : https://www.gurobi.com/academia/academic-program-and-licenses/
-
To install LKH-3.0.6 you can follow the instructions on the project's website: http://webhotel4.ruc.dk/~keld/research/LKH-3/
-
After installing LKH place it in the
Optimized-UV-Disinfection/LKH-3.0.6folder
In order to reproduce the results in the paper, run python {robot_model}_experiments.py.
In order to visualize the results as a movie, the {Robot Model} Animations.ipynb Jupyter notebooks will create a series of still images that can be used to create a movie using ffmpeg or your program of choice.
To use the planner with a different environment, you should be able to simply change the "mesh_file" argument to any of the {robot}_experiments.py file.
Towerbot_experiments.py and floatbot_experiments.py give examples of how to adopt our pipeline to different robots. The first is a mobile base robot that has no rotational joints and a light that is not a point light-source, thus showing how to adapt to more general light models.
floatbot is a robot that floats in 3D space, as though it were a quadrobot carrying a light source. This example shows what changes need to be made in case of larger differences between tested robots and the default robot - armbot.
