Abstract
This paper regards obstacle avoidance and landing as a whole process and proposes a motion planning framework for the quadrotor, which can real-time calculate and enable the quadrotor to avoid obstacles while landing on the mobile platform. Assuming the platform’s motion state is known, the Move-RRT and Move-B-RRT sampling algorithms can establish the static and dynamic trees to obtain the collision-free path containing time information. The algorithm adopts proportional sampling to make the time allocation between path points reasonable. We can determine the static obstacles and mobile platform positions and generate the flight corridor according to the position and time information contained in the path points. After optimization, trajectories represented by piecewise Bézier curves satisfying dynamic constraints are obtained. This paper verifies the motion planning framework in a complex simulation environment.
