## Summary

An analysis of the minimum-snap quadrotor trajectory pipeline: piecewise ninth-order polynomials (ten coefficients) are solved in closed form with snap as the cost and derivative-continuity constraints, while COBYLA trades off time against smoothness. The differential-flat mapping yields thrust and attitude, and geometric control is validated in closed loop in MuJoCo.
