Extended Data Fig. 4: A more complex multi-task demonstration that involves three MAVs.
From: Proximal cooperative aerial manipulation with vertically stacked drones

Two manipulator MAVs (denoted as M1 and M2) collaborate with a toolbox MAV to perform multiple manipulation tasks fully autonomously. a. The complete procedure. An iron plate and a ball were initially placed on top of the right and left pillars, respectively. The goal is to move the iron plate and the ball to the top of the middle pillar so that the ball is placed right on the iron plate. M1 first docked with an electromagnet tool, picked up the iron plate from the right pillar, and placed it on the middle pillar. M2 first docked with a soft gripper tool, picked up the ball from the left pillar, and eventually stacked the ball on the iron plate that had been placed on the middle pillar. b. Snapshots of object manipulation during the task. c. Snapshots of the FlyingToobox system during the task.
