MIT’s new Wi-Fi radar trick lets robots see through walls and find tools buried deep in drawers

mmNorm reconstructs complex hidden shapes using Wi-Fi frequencies without touching the object Robots can now see inside cluttered drawers using reflected signals from surrounding antennas MIT’s technique beat current radar accuracy by 18% across more than 60 tested objects In environments where visibility is obstructed, such as inside boxes, behind walls, or beneath other objects,…

The trouble with MAGA’s manufacturing dream

In the late 1940s, as the industrial capacity of Europe and Japan lay in tatters, America accounted for over half of global manufacturing output, with much of the world heavily reliant on its wares. Last year it accounted for little over a tenth, and imported $1.2trn more in merchandise than it exported—to the displeasure of…
