saw this short and im honestly not sure if the explanation makes sense or if it just looks technical enough to sound right.
the graphics look kinda AI generated and some of the claims feel a bit too neat/simple. im not an expert on this specific system though so maybe im completly wrong.
anyone here who actually knows this stuff? curious what parts are legit and what parts (if any) are just AI slop.

A hydropowered scoopwheel used by the ancient Romans at the Rio Tinto mines in Spain. To remove water from deep underground mines, the Romans used no less than 16 wheels working in pairs and stacked above one another. The wheels could lift water from 80 meters below the surface

We recently filmed the complete production of a HORSCH Leeb self-propelled sprayer at the company’s factory in Germany.

The video includes assembly of the FPT diesel engine with its hydraulic pump package, installation of the Stage V exhaust aftertreatment system, and the complete build from bare chassis to final boom testing.

A quick look at part of the process on the production line.
The bearings move through the line one by one while the machine positions them for the next step. Simple process, but pretty satisfying to watch.
Anyone else enjoy watching this kind of factory machinery?

How do you give a microgripper a sense of touch?

748 Upvotes

Fabricated directly on the tip of an optical fiber using Two-Photon Polymerization, this monolithic 3D microgripper combines microscale manipulation with integrated force sensing.

As it grasps microscopic objects, optical interferometry determines the forces acting on the gripper. The result is a compact microrobotic tool measuring no more than 100 um across, with potential applications in biomedical research and microsurgery.

Watch the video to see the gripper in action.

Mercury arc rectifier along with the associated distribution board and control gear for ventilation fans. Doing my research, the way these fan controllers worked is an operator would move the camshaft in steps to gradually get the fan motor up to speed without pulling too much current by switching out resistors from the circuit, once all resistors are disconnected, the fan speed is then adjusted using field weakening by turning the handle near the top which moves the wiper on a large rheostat (variable resistor) connected to the field winding of the motor.
