# PACNav
This repository contains the scripts and code to run the Gazebo simulations and real-world experiments for the paper titled "PACNav: A Collective Navigation Approach for UAV Swarms Deprived of Communication and External Localization".

### Step 1) Installation and building containers.
- Install `docker` and `singularity` using the install scripts provided in `pacnav/install` directory. You may skip this if you already have these dependencies installed.
- Build the singularity image by running `./singularity/recipe/build.sh`.

### Step 2) Running the container and building the ROS packages.
- After a successful build, run the singularity container using `./singularity/run_singularity.sh` script.
- The script will mount the `singularity/user_ros_workspace` directory into the singularity container.
- Build the required ROS packages by running `catkin build -c` inside `singularity/user_ros_workspace`.

### Step 3) Running the mutli-UAV simulation.
- After a successful `catkin build`, run the multi-UAV simulation using ```./singularity/user_ros_workspace/src/mrs_swarm_core/simulation/simulate_swarm.sh -f config/sim_config.yaml```
- The parameters for setting up the multi-UAV simulation are in the `singularity/user_ros_workspace/src/mrs_swarm_core/simulation/config/sim_config.yaml` file. You can play around with them as you please.
