In this project, I explored a variety of algorithms used quadrotor trajectory planning and implemented each algorithm from scratch. Quadrotor trajectory planning is a pivotal part of autonomous quadrotor systems. These algorithms enable quadrotors, or drones, to autonomously navigate complex environments, performing a wide range of tasks. From surveillance and aerial photography to search and rescue operations, quadrotors are used extensively in applications requiring rapid and agile movement. Accurate trajectory planning ensures obstacle avoidance, stable flight, and efficient use of resources.
