The Distributed Flight Array: Indoor Flight Experiments
Переглядів 37 тис.11 років тому
This video demonstrates autonomous modular flight of the Distributed Flight Array for up to 12 modules. These experiments were performed indoors, where the vehicle was flown in the workspace of a 3D motion capture system. The 3D motion capture system was used for XY-position/velocity and yaw-angle feedback. For more information, visit: www.idsc.ethz.ch/Research_DAndrea/DFA. Researchers: Raymond...

This video demonstrates flight of the Distributed Flight Array using 6 modules flown outdoors in a variety of configurations. A joystick is used to manually control the x and y degrees of freedom (through roll and pitch angles), as well as the yaw-angle. For more information, visit: www.idsc.ethz.ch/Research_DAndrea/DFA.

A concept animation of the Distributed Flight Array (DFA) that is being developed at ETH Zurich. This multi-rotor vehicle consists of autonomous single-rotor modules that are able to drive, dock with its peers, and fly in a coordinated fashion. The goal of this project is to have many modules assemble at random, fly to a predetermined altitude, hover, break apart, fall back down, and then repea...

    any one here play diep.io if so use this technology and computer coding to were you can shoot other people and you start out with one of them robots but there are many around the area that don't move Intel you shoot it or run in to it then it attaches to your drone and adds another gun and drone to it like or comment if you think this idea is cool

    Experiments are rarely applicable to the real world at all. It's not the flight that is interesting here, it's the automated intermodule communication to achieve the goal of the larger unit. The hivemind, almost. The same AI principals function on one unit, 5 units, or 500 units. Apply that concept to things other than just an RC copter and it starts to get really interesting. Science.

    1. In theory, there's no limit to the number of units. 2. They could be programmed to seek a certain pattern, but currently they are not. 3. We have not tried other geometric shapes for units. Choosing hexagons was an aesthetic decision, more than anything else.

    They would be UFOs because they don't know what they are. Kind of comes from the meaning of "unidentified flying object," huh? :)

    I suggest you get in touch with the organizations that are developing space probes, those that launch mission to Mars, Comets etc., build them large enough, and attached the right equipment to each of them, and they can cover more area than just one little rover. Hell, if you wanted, you could market this to Deep sea exploration companies, Oil Companies, and of course it has the military application as well.

    I don't believe contra-rotating blades on their own result in stable flight. You need vanes or something else to counter-act any disturbance in roll/pitch. In any case, we intentionally designed the vehicle such that each unit (or hexagon) is unstable. This was done in order to demonstrate that units need to cooperate in order to fly.

  • @raymondoung
    @raymondoung 11 років тому

    Changing the polarity of the magnets would require some sort of actuation mechanism on the magnets, increasing the complexity (and weight). Yes, reconfiguration would happen in sets of four or more.

  • @raymondoung
    @raymondoung 11 років тому

    You need at least four in this case to counter-act the aerodynamic torques in flight. Otherwise with three, the vehicle would just spin around in flight. Yes, tri-copters exist and are stable. That's because their propellers can generate enough torque to counter-act the torque of two propellers (by means of a larger propeller or a faster motor).

  • @raymondoung
    @raymondoung 11 років тому

    You need four to counter-act the aerodynamic torques in flight. You could use three, but then the vehicle would just spin around (and accelerate!) in flight. So four: two with clockwise (CW) rotating propellers and two with counterclockwise (CCW) rotating propellers. You might ask whether you need an even number of CW and CCW. Not necessarily. The larger the vehicle gets, the less this becomes an issue.

  • @nomadpoet4004
    @nomadpoet4004 11 років тому

    So are you saying reconfiguration would happen in sets of four? I actually started to wondered if you could change the polarity of the magnets, so you could sorta roll it along the arrangement

  • @fallingwater
    @fallingwater 11 років тому

    Shouldn't three be enough? Tri-copters exist and are stable.

  • @ESRogs
    @ESRogs 11 років тому

    Why? Just reconfigure in such a way that every unit is part of a group of four at all times.

  • @ESRogs
