There's a gyroscope in it.

This experiment uses a 3,000 volt spiral electron multiplier with 16 measurement channels.

Hexacopters and octocopters, with six and eight propellers, can provide redundancy, but quadrocopters are much more popular because they have the minimum number of fixed motor propeller pairs four.

Yes, it must be a flying machine. It's got, um, propellers.

And then finally, if you spin opposite pairs of rotors faster than the other pair, then the robot yaws about the vertical axis.

Noting that the usefulness of food micro algae, above all, Spirulina platensis, along with other nutrients, to restore the health of severely malnourished people has been emphasized and recognized in international agreements, namely the Free Agreement for Cooperation in Scientific Research and Humanitarian Use of Micro alga Spirulina as Food and the Convention for the Use of Food Micro alga and Inter University Scientific Research,

Curls on Green

Where's the propellers?

So in this picture you see that rotor four is spinning faster and rotor two is spinning slower.

If you spin these rotors at the same speed, the robot hovers.

United Kingdom of Great Britain and Northern Ireland

So it has four rotors.

OK, so here, this is the book spiral.

It's a double helix.

Spiral In

Noting in particular that the merits of spirulina have been recognized through the adoption of international agreements, namely the Free Agreement for Cooperation in Scientific Research and Humanitarian Use of Micro alga Spirulina as Food and the Convention for the Use of Food Micro algae and the Intergovernmental Institution for the Use of Spirulina against Malnutrition,

If you increase the speed of each of these rotors, then the robot flies up, it accelerates up.

Cockpit, propeller, engine.

A snail's shell is spiral in form.

My spine curves spiral.

You'll be familiar with the double helix of DNA.

At the same meeting, the Secretary General of the Institution for the Use of Micro Algae Spirulina Against Malnutrition made a statement.

And the other way around, if you increase the speed of rotor three and decrease the speed of rotor one, then the robot pitches forward.
