quadcopter

We have developed a computationally efficient trajectory generator for six degrees-of-freedom multirotor vehicles, i.e. vehicles that can independently control their position and attitude. The trajectory generator is capable of generating approximately 500’000 trajectories per second that guide the multirotor vehicle from any initial state, i.e. position, velocity and attitude, to any desired final state in a given time. In this video, we show an example application that requires the evaluation of a large number of trajectories in real time.

Zurich-based robotics company Perspective Robotics this week unveils Fotokite Phi, their first consumer targeted, affordable, accessible, tethered flying camera. The Fotokite Phi is available now for pre-order on Indiegogo for $349 USD.

Researchers at ETH Zurich have developed a new algorithm for robustly controlling a tailsitter flying machine in hover position. Using the algorithm, the tailsitter is able to recover from any orientation, including upside down.

The use of robots to find victims after natural disasters is fast becoming commonplace, with well documented cases where robots have been sent into areas too dangerous for rescue workers.  While the issues surrounding robustness, control and autonomy are frequently cited as key areas for research, a  team from LIS, EPFL and NCCR Robotics is working on another important aspect, how to make flying robots easily transportable and quick to deploy.

High-g-quadrocopter-trainingThis video shows tethered quadrocopters flying steadily together at high speeds exceeding 50 km/h in a confined space. With the tether exerting more than 13 gs of centripetal force, multiple quadrotors are able to fly 1.7m- radius circular trajectories in formation across different orientations in space and then successfully perform a coordinated braking maneuver.

Previously known for consumer products for smartphones, tablets and cars, Paris-based Parrot recently branched into both the consumer and commercial drone businesses.

We developed a new technology that allows a quadrotor to automatically recover and stabilize from any initial condition without relying on external infrastructure like GPS. The technology allows the quadrotor system to be used safely both indoors and out, to recover stable flight after a GPS loss or system failure. And because the recovery is so quick, it even works to recover flight after an aggressive throw, allowing you to launch a quadrotor simply by tossing it in the air like a baseball.

Drone-Failsafe-Algorithm

UPDATE 04/03/2014:

In this video update, we show that a quadrocopter can be safely piloted by hand after a motor fails, without the aid of a motion capture system. This follows our previous video, where we demonstrated how a complete propeller failure can be automatically detected, and that a quadrocopter can still maintain stable flight despite the complete loss of a propeller.

The team at the ETH Flying Machine Arena has released three new videos, demonstrating quadrotors building tensile structures, tossing a ball back and forth, and refining a figure-eight trajectory using iterative learning. Worth the watch!!

ARDroneSubscribingFeedback

This is the third tutorial in the Up and flying with the AR.Drone and ROS series.

In this tutorial we will:

  1. Learn about the AR.Drone’s state feedback (and how it is handled by ROS)
  2. Learn about the AR.Drone’s tag detection
  3. Program our first ROS nodes: A subscriber and a publisher

Raffaello D’Andrea juggles quadrotors at TED Global 2013.

A quadrocopter swoops through the air to serve a glass of water without spilling a drop. Another gets two of its propellers cut off, yet still easily flies across the arena. “It looks like magic!” says ETH Zurich‘s Raffaello D’Andrea, but it took a lot of research, hard work and planning to bring this ‘magic trick’ to TED Global.
