EGO-Planner is a lightweight, ESDF-free gradient-based local trajectory planner for quadrotors, implemented in C++ on ROS. It computes collision-free trajectories in roughly 1 ms without building a Euclidean Signed Distance Field.

Use cases

• plan collision-free trajectories for a quadrotor drone
• run fast local replanning on a UAV in cluttered environments
• avoid building ESDF maps for drone obstacle avoidance
• simulate quadrotor navigation in ROS with obstacle maps
• research benchmark for gradient-based drone planners

When to choose

• you need millisecond-scale local planning for a single quadrotor
• you want an ESDF-free planner that runs on resource-constrained onboard hardware
• you are doing academic research on aerial robotics and want a well-cited baseline

When to avoid

• you need multi-drone swarm planning - use EGO-Swarm instead
• you need global path planning rather than local replanning
• your project is not ROS-based or not on Linux
