Isto é muito bem achado, da Industry News...
Robots que se movem como Minhocas, e podem mover-se por aí, muito mais baratos, pequenos, e fáceis de fazer.
Não vai passar muito tempo até que se faça disto por toda a parte, e nem sei se não vai alguém fazer uma espécie de micro Stepper, e daí uma micro-CNC!
Researchers Make Robots Out of Paper
A team of researchers from the University of Illinois Department of Mechanical Science and Engineering has made a pair of crawling robots, Peri and Poly, out of little more than a sheet of paper, a few 3D printed parts, and a handful of screws.The researchers used origami paper folding to create cheap robots that move like earthworms.Poly is 51 mm wide and uses a pair of origami towers that expand and contract when twisted to make the worm robot crawl forward. The robot has directional feet made of hard plastic and rubber. The 3D-printed toes allow the robot to slide forward while the rubber heal stops it from backsliding. This particular example of bio-mimicry was inspired by the setae on earthworms.Peri is more than twice the size, and fully mobile. Peri is 106 mm wide and runs on batteries unlike the Poly, which is tethered to the power source. Peri also uses on-board controllers to navigate.

Da Página da Facebook, Zink, vem esta ideia muito bem-vinda, usar o velho mecanismo de pesos dos Relógios, para produzir electricidade para iluminar uma casa, em zonas sem Rede Eléctrica.
Muito Bom.
The ProblemOver 1.2 billion people globally have no access to electricity and millions more have an unreliable supply. Instead they use dangerous, polluting and expensive kerosene lamps for light.A typical kerosene lamp is made by taking an empty bottle or tin can, putting a wick in the middle, filling it with fuel and lighting. Using kerosene for lighting is extremely inefficient, dangerous and expensive, and it has extensive health and environmental drawbacks.How It WorksCombining kinetic and potential energy, GravityLight works by connecting an elevated weight — filled with rocks or sand — to a pulley system that slowly powers a generator as the weight falls to the ground.
Para se divertirem um pouco, fiquem com esta ideia, que é uma boa maneira de renovarem a Novidade dos Fidget Spinners:
Electromagnetic Fidget Spinner Acceleratortanner_tech
Fidget Spinners are little plastic toys with a bearing in the center. They are fun for a little bit, but get boring after a while due to their slow spinning speeds. There are ways to make them spin faster, but these methods involve using a bulky air compressor or an expensive can of compressed air. Luckily, I have found a cheap way to accelerate these fidget spinners to extremely high speeds with the power of electromagnetism. You can even hold the spinner in your hand while you accelerate it! I have clocked a spinner that is spinning with this accelerator at speeds up to 1440 RPM, that is fast. You can build this accelerator too, it is really cheap and really simple to build.
