search-and-rescue

Open-source MAVLink fleet operations for PX4: SITL, drone shows, search and rescue, cooperative autonomy, and field validation

The Open Source Computer Aided Dispatch (CAD), Personnel, Shift Management, Automatic Vehicle Location (AVL) and Emergency Management Platform that powers Resgrid.com

Retired September 27, 2026. Final v1.7.0 source retained for reference; no new store downloads or purchases. Development continues in Red Grid MGRS, whose Meshtastic radio features do not replace Link phone-to-phone transport.

Offline group-safety mesh for hikers: ESP32 + GPS + LoRa, with a firmware-in-the-loop simulator and 3D replay viewer

Code for our paper LLaMAR: LM-based Long-Horizon Planner for Multi-Agent Robotics

Industrial cooperative-UAV fleet coordination in Rust — formation keeping, Raft consensus, cooperative task allocation, RRT-APF collision avoidance & MAPPO navigation for civilian SAR / inspection / agriculture

[ICRA 2026] Official implementation of OTAS: Open-vocabulary Token Alignment for Outdoor Segmentation. Training-free language-grounded environment reconstruction and semantic segmentation. Built for in the wild, real-time robotic applications in unstructured and uncooperative environments.

This project uses the video from a small unmanned aerial system to autonomously navigate an unmanned surface vehicle covered in a flotation jacket to reach drowning victims.

Encrypted off-grid LoRa radio firmware for the LILYGO T-Deck (drone scanning, 2.4GHz/BLE RemoteID, Walkie Talkie, images, and more!)

Offline-first MGRS navigation for iOS and Android: coordinates, waypoint routes, imported offline maps and optional Meshtastic radios. Free core tools with paid Pro workflows. Source available under a restricted license. Red Grid Link is retired.

Multi-Agent Search and Rescue Robot in ROS

Python and MATLAB codes for Density-Driven Optimal Control (D2OC) using Optimal Transport and Wasserstein distance, enabling decentralized multi-agent / multi-robot non-uniform area coverage.

This is a ROS package designed to implement Q-learning algorithm for the autonomous navigation of unmanned aerial vehicles (UAVs) in search-and-rescue (SaR) operations. It can also be used to train other reinforcement learning algorithms on UAVs. A PID algorithm is employed for position control.

Drifters Project

A library of algorithms for "bearings only target localization" --- primarily intended for radio direction finding

Lightweight UAV-SAR perception system for aerial human detection, monocular GPS geolocation, and automated rescue alerting using standard UAV telemetry and edge AI.

OmniSeekers is a robotic platform for search-and-rescue tasks, featuring a swarm of affordable omnidirectional robots. It combines Bug Algorithms and Bluetooth-based communication to explore indoor environments without GPS or SLAM, offering efficient, centralized control and modular development.

SentinelBlue is an edge-deployed deep learning system for autonomous maritime search and rescue, featuring real-time RGB and thermal fusion for robust detection of distressed individuals and watercraft from UAV platforms.
