The classic image of a robot is one clad in a rigid metal shell, but that might not be practical in situations where man and machine will need to work together. The emerging field of soft robotics is helping to make that collaboration safer, but recreating muscle is no easy task. Now, mechanical engineers from Columbia University have developed a synthetic soft muscle that’s said to be much more simple to make and run than others, and is three times stronger than the real thing.
Most soft robots are powered by pneumatic or hydraulic systems, with their movements controlled by filling and emptying bladders with liquids or gases. The problem is, that usually requires bulky external components like compressors, which prevent the systems from being shrunk down to practical sizes.
The system developed by the Columbia team is based on a natural muscle. It’s made of silicone rubber matrix pocked with micro-bubbles of ethanol, giving the material low density and high elasticity. It can be 3D printed into whatever shape is needed, then electrically actuated thanks to a thin resistive wire embedded inside. Altogether, it can be made easily, cheaply and safely.
A robot in China has successfully performed dental surgery on a volunteer. The recent procedure records the first successful autonomous implant surgery, and could change the way dental surgery is performed in China.
Brave Volunteer, Successful Surgery
Would you willingly get dental surgery from a robot? One woman did and because of her bravery, experts saw how the robot was able to perform dental surgery successfully and efficiently — not to mention she got two of her teeth replaced with dental implants.
Innovation will do more good than harm, he says.
You know a topic is trending when the likes of Tesla’s Elon Musk and Facebook’s Mark Zuckerberg publicly bicker about its potential risks and rewards. In this case, Musk says he fears artificial intelligence will lead to World War III because nations will compete for A.I. superiority. Zuckerberg, meanwhile, has called such doomsday scenarios “irresponsible” and says he is optimistic about A.I.
But another tech visionary sees the future as more nuanced. Ray Kurzweil, an author and director of engineering at Google, thinks, in the long run, that A.I. will do far more good than harm. Despite some potential downsides, he welcomes the day that computers surpass human intelligence—a tipping point otherwise known as “the singularity.” That’s partly why, in 2008, he cofounded the aptly named Singularity University, an institute that focuses on world-changing technologies. We caught up with the longtime futurist to get his take on the A.I. debate and, well, to ask what the future holds for us all.
