Flying object propels itself by flipping inside out

It's not a bird or a plane: it's an unusual flying object that propels itself by flipping inside out. Created by engineers at Festo in Esslingen, Germany, the floating band filled with helium takes on different shapes while expanding and contracting to generate thrust and move through the air.
The design is based on the inverted cube shape discovered by inventor and mathematician Paul Schatz. By dissecting a cube into three parts, two star-shaped units can be produced at either end with an invertible belt in the middle section which is the same shape as the flying band. The system reproduces the entire structure: it opens to release the band while the ends remain on the ground as a docking station.
The flying object itself is made up of six identical prisms filled with helium, held together by a carbon-fibre framework. Three motors drive the motion coordinated by a tiny onboard computer, pre-programmed to replicate the inversion sequence. Using a smartphone, a person on the ground can guide the object around a room, which will be demonstrated on Monday at a trade show in Hanover, Germany.
The firm still hasn't come up with a specific use for inversion-driven propulsion. The mechanics of automated systems are typically based on rotational or linear motion to drive, for example, motors or grippers, but inversion is seldom used in designs. The company has now launched a competition challenging students in Germany to suggest a functional idea that could be implemented in an industrial environment.

"Ethics" is simply a last-gasp attempt by deist conservatives and
orthodox dogmatics to keep humanity in ignorance and obscurantism,
through the well tried fermentation of fear, the fear of science and
new technologies.
 
There is nothing glorious about what our ancestors call history, 
it is simply a succession of mistakes, intolerances and violations.
 
On the contrary, let us embrace Science and the new technologies
unfettered, for it is these which will liberate mankind from the
myth of god, and free us from our age old fears, from disease,
death and the sweat of labour.

WARNING FROM RAEL: For those who don't use their intelligence at its
full capacity, the label "selected by RAEL" on some articles does not
mean that I agree with their content or support it. "Selected by RAEL"
means that I believe it is important for the people of this planet to
know about what people think or do, even when what they think or do is
completely stupid and against our philosophy. When I selected articles
in the past about stupid Christian fundamentalists in America praying
for rain, I am sure no Rael-Science reader was stupid enough to
believe that I was supporting praying to change the weather. So, when
I select articles which are in favor of drugs, anti-semitic,
anti-Jewish, racist, revisionist, or inciting hatred against any group
or religion, or any other stupid article, it does not mean that I
support them. It just means that it is important for all human beings
to know about them. Common sense, which is usually very good among our
readers, is good enough to understand that. When, like in the recent
articles on drug decriminalization, it is necessary to make it
clearer, I add a comment, which in this case was very clear: I support
decriminalizing all drugs, as it is stupid to throw depressed and sad
people (as only depressed and sad people use drugs) in prison and ruin
their life with a criminal record. That does not mean that there is
any change to the Message which says clearly that we must not use any
drug except for medical purposes. The same applies to the freedom of
expression which must be absolute. That does not mean again of course
that I agree with anti-Jews, antisemites, racists of any kind or
anti-Raelians. But by knowing your enemies or the enemies of your
values, you are better equipped to fight them. With love and respect
of course, and with the wonderful sentence of the French philosopher
Voltaire in mind: "I disapprove of what you say, but I will defend to
the death your right to say it".
