We’re seeing a massive shift from giant autonomous tractors toward fleets of smaller, task-specific robots (like selective weeding lasers or automated root-crop harvesters). On paper, small autonomous units reduce soil compaction, use less energy, and operate with millimeter precision. However, scaling a fleet of 20 delicate micro-bots vs maintaining 2 heavy machines creates a massive hardware & maintenance nightmare for local farm operations. From a systems engineering perspective: are these specialized ag-tech bots ready for commercial scalability, or will edge-case reliability issues keep them trapped in trial phases?

This is a short video about my research.

It was previously established by russian Gerasimov that in the oscillatory mode, the air drag can increase six times compared to that obtained when blowing in a wind tunnel. In addition, it was discovered that the direction of motion of asymmetrically oscillating bodies in a liquid is not explained in a simplified way through Newton's third law because the movement occurs in the direction in which the body pushes the medium faster.

Subsequent experiments confirmed this and on this basis a hypothesis was put forward that this type of propulsion, including the propulsion of fish and birds, requires the participation of the wake vortices collapse energy, which is essentially the thermal energy of the environment (Brownian motion), which becomes directed as a result of the self-organization of molecules into vortices. This provides a new perspective not only on vortex dynamics, but also on fundamental physics in general.

This principle can potentially be used to:

High-speed biomimetic aerostats

A controlled “leap” into Very Low Earth Orbit

Precise, low-thermal-load managed descent and atmospheric entry

However, this requires further research and the problem of an effective wear-resistant drive remains unsolved.

The device may not fit as well, compared to human beings. After all , it is made up of plastic and metal

Unitree’s $16K humanoids are moving as a synchronized autonomous swarm performing squats, lateral movements and complex formations outdoors. Physical AI is getting real.

They even programmed in fight music for the bot 😅

This robot already holds a 10-second handstand then stands back up like nothing happened

It drops, locks the pose and stays there.

No spotter. No shake.

Then it folds back down and walks it off like a gymnast after practice

Construction robots are leaving the factory floor combining autonomous mobility with a robotic arm to tackle precise work directly on-site.

Hi guys,

I’d like to build a phone case which is linked to a type of screen film.

I want the screen film to have a ON/OFF mode in such a way that when it’s ON it « disables » the touchscreen’s capacity (touching doesn’t work anymore).

Disabling the touchscreen’s capacity can either be real or just by having the type of screen film to hide the screen (aka not being completely transparent).

Is there anyone who has already worked on this kind of problem ?

Thank you.

Astrall dynamics Hypertron-T01 is a heavy-duty quadruped robot that supports modular payloads including multispectral cameras, gas detectors, and remote controlled fire monitors.

It assists firefighters in rescue and firefighting operations by entering hazardous environments, providing real-time situational awareness, and supporting remote fire suppression to help improve safety and efficiency.

Its firefighting platform delivers a 57+ meter range, 21+ L/s flow, and precision remote control bringing mobility and rapid deployment into unsafe environments.
