Waste plastic could be spun into eco-friendly clothing (engineering, design)

INTRO: MIT engineers have found a new use for a common plastic, managing to spin polyethylene into fabric that can passively cool the wearer by allowing heat through and moisture to evaporate. The discovery could see waste plastic bags being turned into sportswear.


Shape-shifting robots in the wild: the DyRET (engineering, design)

EXCERPT: DyRET, the Dynamic Robot for Embodied Testing, or “the animal” in the Norwegian of its creator, Tønnes Nygaard, was designed to explore the idea of a shape-shifting robot. Each of DyRET’s four legs has two telescopic sections, so that it can change the length of its thigh or shin bones. The adjustments are made by motors built into the legs and the lengths can be changed automatically while the robot is operating.

The motors can change the height of DyRET by around 20%, from 60cm to 73cm tall. That 13cm makes a dramatic difference to the robot’s walk. With short legs, DyRET is stable but slow, with a low centre of gravity. In its tallest mode, DyRET is more unstable while it walks but its stride is much longer, allowing it to travel faster and to step over obstacles. DyRET also has sensors to keep track of what it’s walking on. Each of DyRET’s feet has a force sensor that can feel how hard the ground is. A 3D camera points at the ground between DyRET’s front legs to estimate how rough the ground is.

When DyRET is walking, it continuously senses the environment through its feet and 3D camera. When the robot detects a change in ground conditions, it can change to the best leg length. But how does the robot know what body shape works best? We explored two ways for DyRET to learn the best leg configuration for different situations: a controlled environment, indoors with known surfaces, and a real-world test outside... (MORE - details)
