broad group

Time-lapse of Broad Group erecting a 30-story prefabricated hotel (J57) in Changsha, China in about 15 days. The description touts modular construction's precision, speed and low waste.

A Microsoft Research demo from TechFest 2012 of a lab touch system that lets viewers feel the effect of different input latencies, down to about 1 ms. It shows how much more responsive dragging feels compared with typical 100 ms touch delay.

CNLohr explains how he made an ESP32 produce valid LoRa packets without a LoRa radio, using aliasing and clever signal tricks. It walks through the RF math and shows how far the signals reach.

A University of Tokyo lab demonstrates a book scanner that flips pages automatically and scans over 250 pages per minute. It uses real-time 3D recognition of the flipped pages and then restores each one to a flat image.

A University of Tokyo demo of a rock-paper-scissors robot that always wins, using high-speed vision to read the human hand and respond faster than people can perceive.

A KUKA commercial staging a table tennis match between German star Timo Boll and a KUKA KR AGILUS industrial robot. It is a polished showcase of robot speed and precision.

The Michigan TypeScript group shows the Doom engine running entirely inside the TypeScript type system. It is open source, and two follow-up videos cover why and how they did it.

A SIGGRAPH demo from Yoichi Ochiai's group of aerial and volumetric graphics drawn by focused femtosecond lasers with computational holography. The plasma points can be touched.

A Discovery Channel computer simulation of a large asteroid impact on Earth, showing the scale of the devastation. It sits in a broader context of early Earth impacts and the moon-forming collision.

A Berkeley PR2 robot autonomously folds a pile of five previously unseen towels, shown at 50x speed. The video accompanies a 2010 ICRA paper from Pieter Abbeel's group.

Cody's Lab collects a sample of dust from the side of a highway and refines it to recover platinum-group metals deposited by catalytic converters. The video walks through the chemistry of separating and assaying the precious metals.
