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
