RoboMaster S1 - DJI's first ground-based gaming robot

DJI has released RoboMaster S1, a modular construction toy that is the first ground bot released by this manufacturer.

The robot has omnidirectional wheels, a powerful processor, a set of sensors, a camera, and even a gel bead gun.

Children can not only build the bot, but also program new movements. Though the basic programming system is also quite comprehensive.

Soil is full of life

In just one teaspoon of soil, there are more microorganisms than people on the planet. “Millions of species and billions of organisms—bacteria, algae, microscopic insects, earthworms, beetles, ants, mites, fungi, and more—represent the greatest concentration of biomass anywhere on the planet,” according to the U.S. Department of Agriculture.

Allergic reaction at the micro level

The animation gives an example of the onset of this process on the skin of the forearm.
That is, the allergen most likely had a contact effect.

The mast cells are the first to react to this contact. They relay information to all the inflammatory mediators, which provoke redness, swelling, local fever and pain.

One of the most important elements in this chain of reactions is histamine ☝🏻
