This is a highly-optimized implementation for minimum jerk/snap trajectories with exact gradient w.r.t. time allocation and waypoints. All involved computations enjoy linear time and space complexity. It is based on completely analytical results of our paper. Only two header files are all you need to use our module as a super efficient differentiable black box.

TGK-Planner: An Efficient Topology Guided Kinodynamic Planner for Autonomous Quadrotors
A lightweight gradient-based local planner without ESDF construction, which significantly reduces computation time compared to some state-of-the-art methods. The total planning time is around 1ms for a trajectory with normal scale.

EGO-Planner: An ESDF-free Gradient-based Local Planner for Quadrotors
A library for generating large-scale piecewise polynomial trajectories for aggressive autonomous flights, with highlights on its superior computational efficiency and simultaneous spatial-temporal optimality. Besides, an extremely fast feasibility checker is designed for various kinds of constraints. Our method is capable of computing a spatial-temporal optimal trajectory with 60 pieces within 5ms, i.e., 200Hz.
