## Quadrotor Control, Path Planning and Trajectory Optimization <a href="https://youtu.be/lA2B1YDLJaY"> <img src="imgs/hover.jpg" alt="step" width="600"> </a> (Click above image for real quadrotor demos) Following [MEAM 620 Advanced Robotics](https://alliance.seas.upenn.edu/~meam620/wiki/) course at University of Pennsylvania. (For Penn students: *DO NOT* spoil the fun by looking at this repo and not working on your assignments! and most importantly, *DO NOT* violate the honor code!) This repo includes matlab code for: - Quadrotor PD controller - Path planning algorithms (Dijkstra, A*) - Trajectory optimizations (Minimum Snap/Acceleration Trajectory) Please cite this work using the following bibtex if you use the software in your publications ``` @software{Lu_yrlu_quadrotor_Quadrotor_Control_2022, author = {Lu, Yiren}, doi = {10.5281/zenodo.6796215}, month = {7}, title = {{yrlu/quadrotor: Quadrotor Control, Path Planning and Trajectory Optimization}}, url = {https://github.com/yrlu/quadrotor}, version = {1.0.0}, year = {2017} } ``` ## PD Controller - Run code: change trajectories in file `control/runsim.m` and run. - See [quadrotor_dynamics.pdf](quadrotor_dynamics.pdf) for dynamic modeling of the quadrotor. - See `control/controller.m` for implementation of the PD controller. - Visualization below.
