Drones are agile things, but they’re not exactly known for their quick reactions.
If you want to knock one out of the sky, a well-thrown ball or even a spear should do the trick.
You can see the quadcopter showing off these skills in the video above (though no-one tested it with a wrench).
And okay, some of those throws are pretty easy, but the drone is still reacting completely autonomously.
“We wanted to really push the boundaries and see what these robots are capable of,” University of Zurich research Davide Falanga told The Verge.
Giving drones an auto-dodge feature would be handy for a lot of use-cases.
