Publications - Flying Machine Arena. Video: Throwing and catching an inverted pendulum – with quadrocopters. Two of the most challenging problems tackled with quadrocopters so far are balancing an inverted pendulum and juggling balls. My colleagues at ETH Zurich’s Flying Machine Arena have now combined the two. As part of his Master thesis Dario Brescianini, student at ETH Zurich’s Institute for Dynamic Systems and Control, has developed algorithms that allow quadrocopters to juggle an inverted pendulum. If you are not sure what that means (or how that is even possible), have a look at his video “Quadrocopter Pole Acrobatics”: (Don’t miss the shock absorber blowing up in smoke at 1:34!)
The Math A quadrocopter with a plate for balancing the pole. The cross-shaped cut-outs are used for easy attachment to the vehicle and have no influence on the pendulum’s stability. To achieve this feat, Dario and his supervisors Markus Hehn and Raffaello D’Andrea started with a 2D mathematical model. This first step allowed to determine (theoretical) feasibility.

If I were to cut the arms off of the circuit board, would that damage the functionality of the quadcopter? Just make sure not to "break" them off, since this kind of force might affect the MEMS sensors. Answered by Marcus Eliasson | 2014-03-18 No, it shouldn't since there are no signals routed out onto the arms that holds the motors. Is this compatible with the JR DSM2/DMSS transmitter? It could be compatible with a transmitter using the Nordic radio chip (like the E-Sky transmitter). What is the best joystick to control a Crazyflie? The best one I've seen is a USB PlayStation 3 controller. Autonomous quadrocopters fly in 20-strong formation. The nanobot quadrocopters at the University of Pennsylvania's General Robotics, Automation, Sensing and Perception (Grasp) laboratory continue to go from strength to terrifying strength.
We've seen the autonomous vehicles flip, roll and even zip through tight windows with impeccable grace. We've seen them sport a pincer-like claw for picking up a payload. If the object is too heavy, multiple machines can work together to offset the weight. The autonomous micro-helicopters are also adept architects, and can work together to construct complex towers. In their latest performance, Grasp engineers show how massive groups of quadrocopters can work together in large formations. "We developed a method to transition between formations in 3D," a Grasp researcher says, as a perfectly aligned battalion of 20 drones suddenly spirals out into a large ring.
