Can you toss a pole by its tip and catch it by the other end? These flying quadrotors can.
Researchers at ETH Zurich posted a video showing two quads tossing a pole in midair.
Dario Brescianini and colleagues at ETH Zurich's Flying Machine Arena developed algorithms for the game based on a 2D mathematical model of the ideal trajectory.
To test the model, the machines were fitted with 4.7-inch circular plates that they used to both throw and catch the pole, which was fitted with flour-filled balloons at the tips to act as shock absorbers. … Read more
