VIO based Navigation for a quadrotor

The goal of the project was to develop a complete planning and control system with state estimation using visual inertial odometry (VIO) for a quadrotor, enabling it to fly from an initial point to a goal point efficiently and without collision with obstacles or crashing. With perfect information of the state of the system aggressive trajectories and controllers were feasible. With state estimation, however, aggressive trajectories designed in prior projects are not feasible due to tracking errors in position and attitude of the quadrotor introduced by the Visual Inertial Odometry(VIO) that is sensitive to themotion of the quad-rotor. Thus, this project aims to outline the changes made in the trajectory generation and controls of the system, in order for the quadrotor to perform well under the constraints introduced by state estimation.
