Our system supports lidar, stereo, and RGB-D sensing, and it includes a novel inter-robot loop closure prioritization technique that reduces inter-robot communication and accelerates the convergence.
To clone Swarm-SLAM:
sudo apt install python3-vcstool
git clone https://github.com/MISTLab/Swarm-SLAM.git
cd Swarm-SLAM
mkdir src
vcs import src < cslam.repos
Packages summary:
- cslam: contains the Swarm-SLAM nodes;
- cslam_interfaces: contains the custom ROS 2 messages;
- cslam_experiments: contains examples of launch files and configurations for different setups;
- cslam_visualization: contains an online (optional) visualization tool to run on your base station to monitor the mapping progress.
Follow the start-up instructions to install, build and run Swarm-SLAM.
