語順訳 - マルクス・フィッシャー: 鳥のように飛行するロボット

It is a dream of mankind/ to fly like a bird.// Birds are very agile.// They fly, not with rotating components,/ so they fly only/ by flapping their wings.// So we looked at the birds,/ and we tried to make/ a model/ that is powerful,/ ultralight,/ and it must have excellent aerodynamic qualities/ that would fly by its own/ and only/ by flapping its wings.//

So/ what would be better [ than ]/ to use the Herring Gull,/ in its freedom,/ circling and swooping over the sea,/ and [ to ] use this/ as a role model?// So we bring a team together.// There are generalists/ and also/ specialists/ in the field of aerodynamics/ in the field of building gliders.// And the task was to build an ultralight indoor-flying model/ that is able to fly over your heads.// So be careful later on.// And this was one issue:/ to build it/ that lightweight/ that no one would be hurt/ if it fell down.//

So/ why do we do all this?// We are a company/ in the field of automation,/ and we'd like to do/ very lightweight structures/ because that's energy efficient,/ and we'd like to learn/ more/ about pneumatics and air flow phenomena.//

So I now would like you/ to [ put ]/ your seat belts/ on and put your hats [ on ] .// So maybe/ we'll try it once --/ to fly a SmartBird.// Thank you.//

So we can now look at the SmartBird.// So here is one/ without a skin.// We have a wingspan of about two meters.// The length is one meter and six,/ and the weight,/ it is only 450 grams.// And it is all/ out of carbon fiber.// In the middle/ we have a motor,/ and we also have a gear/ in it,/ and we use the gear/ to transfer the circulation of the motor.// So/ within the motor,/ we have three Hall sensors,/ so we know exactly/ where the wing is.// And/ if we now beat up and down ...// we have the possibility/ to fly like a bird.// So/ if you go down,/ you have the large area of propulsion,/ and/ if you go up,/ the wings are not that large,/ and it is easier/ to get up.//

So,/ the next thing/ we did,/ or the challenges/ we did,/ was to coordinate this movement.// We have to turn/ it,/ go up/ and go down.// We have a split wing.// With a split/ wing we get the lift/ at the upper wing,/ and we get the propulsion/ at the lower wing.// Also,/ we see/ how we measure the aerodynamic efficiency.// We had knowledge/ about the electromechanical efficiency/ and then/ we can calculate the aerodynamic efficiency.// So therefore,/ it rises up/ from passive torsion/ to active torsion,/ from 30 percent up to 80 percent.//

Next thing/ we have to do,/ we have to control and regulate the whole structure.// Only/ if you control/ and regulate it,/ you will get/ that aerodynamic efficiency.// So the overall consumption of energy is about 25 watts/ at takeoff and 16 to 18 watts/ in flight.// Thank you.//

(Applause)//

Bruno Giussani:/ Markus,/ I think/ that we should fly it once more.//

Markus Fischer:/ Yeah,/ sure.//
