The Circular Cloverleaf Blind Juggler - IDSC ETH Zurich TheBlindJuggler 2015-06-03 | The Circular Cloverleaf Blind Juggler further pushes the boundary of sensorless robotic juggling. Featuring four tilted paddles, the machine can bounce balls from paddle to paddle in a circular motion. The machine has no sensors to detect the ball - it was designed to be able to juggle without any sensing.This video was produced by the Institute for Dynamic Systems and Control (IDSC) at ETH Zurich, Switzerland - http://www.idsc.ethz.ch/More info: http://www.blindjuggler.org.

Periodic Orbits - Blind Juggler - IDSC ETH Zurich TheBlindJuggler 2012-01-17 | This video was produced by the Institute for Dynamic Systems and Control (IDSC) at ETH Zurich, Switzerland - http://www.idsc.ethz.ch/More info about the Blind Juggler: http://www.blindjuggler.org.We demonstrate the different stable periodic orbits that exist for the Blind Juggler using the Cloverleaf paddle. Each of these periodic orbits (= repetitive ball motions) is locally stable. The balls need to be dropped at the right time and from the right height such that the ball ends up in the desired orbit. We use this paddle for research in the control of nonlinear dynamic systems.Lead researchers: Philipp Reist and Raffaello D'Andrea

The Blind Juggler Cloverleaf Paddle - IDSC - ETH Zurich TheBlindJuggler 2011-01-27 | This video was produced by the Institute for Dynamic Systems and Control (IDSC) at ETH Zurich, Switzerland - http://www.idsc.ethz.ch/More info about the Blind Juggler: http://www.blindjuggler.org.The Blind Juggler is a robot that is able to juggle balls without any sensors detecting the ball. We developed the Cloverleaf Paddle, which allows the Blind Juggler to juggle up to 4 balls at the same time. We can illustrate properties of nonlinear systems with the Cloverleaf: For the same paddle motion, there exist multiple stable ball modes (stable periodic orbits), as shown in the video, at the end.Lead researchers: Philipp Reist and Raffaello D'Andrea
Chaos on the Blind Juggler - IDSC - ETH Zurich TheBlindJuggler 2011-01-27 | This video was produced by the Institute for Dynamic Systems and Control (IDSC) at ETH Zurich, Switzerland - http://www.idsc.ethz.ch/More info about the Blind Juggler: http://www.blindjuggler.org.We demonstrate chaos on the Blind Juggler using the Cloverleaf Paddle. When the paddle is moving with an appropriate amplitude and frequency, the ball starts to move chaotically. We are exploring how we can use this effect for controlled state transitions. The basic idea is illustrated in this video: After activating chaos, we switch back to the motion that stabilizes multiple different ball trajectories. Depending on the states of the balls at switching time, a different juggling pattern evolves after switching. If we measure the states of all balls and if we could predict which pattern evolves after switching, we could create arbitrary patterns autonomously.Lead researchers: Philipp Reist and Raffaello D'Andrea
