Quadrotor control, path planning and trajectory optimization

Quadrotor Control, Path Planning and Trajectory Optimization

(Click above image for real quadrotor demos)

Following MEAM 620 Advanced Robotics 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)

PD Controller

• Run code: change trajectories in file control/runsim.m and run.
• See quadrotor_dynamics.pdf for dynamic modeling of the quadrotor.
• See control/controller.m for implementation of the PD controller.
• Visualization below. Desired (blue) vs Actual (red)

Trajectory 1: Step

Trajectory 2: Circle

Trajectory 2: Diamond

Path Planning and Trajectory Optimization

• Run code: traj_planning/runsim.m and run path 1 or path 3.
• See project_report.pdf for more details about trajectory generation
• See traj_planning/path_planning/dijkstra.m for implementation of path finding algorithms (dijstra, A*).
• See traj_planning/traj_opt7.m for implementations of minimium snap trajectory.
• See traj_planning/traj_opt5.m for implementations of minimium acceleration trajectory.
• Visualization below.
