Where's the propellers?

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

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.

So it has four rotors.

OK, so here, this is the book spiral.

It's a double helix.

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

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

Emphasizes the importance of intensifying and assisting national activities for the production and use of food micro algae, especially in member countries of the Intergovernmental Institution for the Use of Micro alga Spirulina against Malnutrition

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

Your monkey wrench, Mr. Newton.

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,

So there's a strand that goes like this, goes along one helix and binds it jumps to another helix and comes back.

This is DNA in its classic double helix form.
