Aerial interaction requires aerial robots capable of independent attitude control, leading to the rising popularity of omnidirectional tiltable multirotors (tilt-multirotors). Unlike standard multirotors that rely on differential flatness to generate high-quality trajectories, tilt-multirotors possess servo-integrated nonlinear dynamics. Consequently, their trajectory optimization becomes a challenging nonconvex problem, generally suffering from high initialization sensitivity and computational costs. To address these challenges, we propose the penalized trust-region sequential convex programming with line search framework.
