Why does the pickup station in the videos have cones? Does the drone need to have such long legs?

While the Rotolatch™ system can accommodate for substantial misalignment, precision landing with manually controlled, hobby level drones is quite difficult. The cones on the pickup station align the drone to the package upon landing. Slightly more advanced drones can reverse this and put small funnels on the drones with alignment poles protruding for the pickup station. Even more advanced drones may not need alignment assistance at all.
