Open-Source Code

Initially released in 2020, EGO-Planner is a
lightweight, highly-optimized, robust, gradient-based local planner, which significantly reduces computation time compared to some state-of-the-art methods. The total planning time is only
around 1ms without ESDF construction.
EGO-Swarm is a decentralized and asynchronous systematic solution for multi-robot autonomous navigation in unknown obstacle-rich scenes using merely onboard resources. Evolved from EGO-Planner, EGO-Swarm shares identical obstacle-avoidance algorithms with EGO-Planner but has several new modules added for swarm implementation.
EGO-Planner-v2 is an evolution of EGO-Swarm. 1. We introduce MINCO, a trajectory optimization backend that offers higher optimality with lower computation than EGO-Swarm. 2. We provide a variety of new implementations, such as swarm formation, multi-agent tracking, dynamical obstacle avoidance, swarm manipulation interface and more. 3. The hardware is first released along with testing data on zenodo.
