For real, outdoors: SCAMP robot can fly, perch, climb

We love the impressive video watch of Atlas biped models, super-sized machine wonders trekking through craggy terrain, undeterred by snow, mud and ice, ready to haul supplies and go where no humans dare to go in times of ...

One-dimensional objects morph into new dimensions

A line is the shortest distance between two points, but "A-line," a 4-D printing system developed at Carnegie Mellon University, takes a more circuitous route. One-dimensional, "line"-shaped plastic structures produced with ...
