Rogue waves Prediction?

Rogue WavesIt’s bad enough to be on the sea during a storm, with the ship rocking in the high winds and rolling with the tempest-tossed waves. But it could always be worse. Rogue waves are twice as large as the surrounding waves, which in stormy seas can be absolutely massive. Seafarers have reported waves like this over 110 feet tall, large enough to swamp a ship.

Rogue waves are unpredictable, coming seemingly out of nowhere. Until now, the only warnings that a Continue reading


Boston Dynamics promoting the new version of Atlas

boston-dynamics-atlasA new version of Atlas, designed to operate outdoors and inside buildings. It is specialized for mobile manipulation. It is electrically powered and hydraulically actuated.

It uses sensors in its body and legs to balance and LIDAR and stereo sensors in its head to avoid obstacles, assess the terrain, help with navigation and manipulate objects. This version of Atlas is about 5′ 9″ tall (about a head shorter than the DRC Atlas) and weighs 180 lbs. In the next video Continue reading


4D Printing: Shapeshifting Architecture


A team at the Wyss Institute and Harvard SEAS has developed a new micro-scale printing method to create transformable objects. These “4D-printed” objects go a step beyond 3D printing to incorporate a fourth dimension–time.
The method was inspired by the way plants change shape over time in response to environmental stimuli. This orchid-shaped structure is printed with a hydro gel composite ink containing aligned cellulose fibrils, which enable an-isotropic swelling. A proprietary mathematical model developed by the team precisely predicts how the fibrils will swell in water. Continue reading
