MIT researchers have utilized a new reinforcement learning technique to successfully train their mini cheetah robot into hitting its fastest speed ever, reports Matt Simon for Wired. “Rather than a human prescribing exactly how the robot should walk, the robot learns from a simulator and experience to essentially achieve the ability to run both forward and backward, and turn – very, very quickly,” says PhD student Gabriel Margolis.
MIT researchers have created a new computer algorithm that has allowed the mini cheetah to maximize its speed across varying types of terrain, reports Shi En Kim for Popular Science. “What we are interested in is, given the robotic hardware, how fast can [a robot] go?” says Prof. Pulkit Agrawal. “We didn’t want to constrain the robot in arbitrary ways.”
MIT researchers have used a new reinforcement learning system to teach robots how to acclimate to complex landscapes at high speeds, reports Emmett Smith for Mashable. “After hours of simulation training, MIT’s mini-cheetah robot broke a record with its fastest run yet,” writes Smith.
CSAIL researchers developed a new machine learning system to teach the MIT mini cheetah to run, reports James Vincent for The Verge. “Using reinforcement learning, they were able to achieve a new top-speed for the robot of 3.9m/s, or roughly 8.7mph,” writes Vincent.
Gizmodo reporter Andrew Liszewski writes that CSAIL researchers developed a new AI system to teach the MIT mini cheetah how to adapt its gait, allowing it to learn to run. Using AI and simulations, “in just three hours’ time, the robot experienced 100 days worth of virtual adventures over a diverse variety of terrains,” writes Liszewski, “and learned countless new techniques for modifying its gait so that it can still effectively loco-mote from point A to point B no matter what might be underfoot.”
Popular Science reporter Tatyana Woodall writes that CSAIL researchers have developed electromagnetic bot blocks that can reconfigure into various shapes and could potentially help astronauts build in space. “The electromagnetic lining of the 3D printed frames allows cubes to seamlessly attract, repel, or even turn themselves off,” writes Wood. “One cube takes a little over an hour to make, and only costs 60 cents.”
Writing for The Wall Street Journal, Prof. Yossi Sheffi notes that “just-in-time” (JIT) supply chains can help improve product quality and manufacturing processes, leading to reduced inefficiency. JIT “reinforces resilience because it strengthens the relationships along the supply chain between companies, their suppliers and customers,” writes Sheffi. “Close relationships allow companies to react collaboratively to supply-chain disruptions.”
A team of scientists from MIT and Facebook have created a new object tagging system called InfraredTags, reports Charlotte Hu for Popular Science. “InfraredTags uses infrared light-based barcodes and QR codes that embedded permanently into the bodies of 3D printed objects,” reports Hu.
MIT researchers have been working to turn polyethylene plastics into woven fabrics, reports Smithsonian Magazine reporter Frederick Reimers. “We strongly believe that adoption of PE textiles will be very beneficial for the world from the sustainability standpoint,” says Principal Research Scientist Svetlana Boriskina tells Reimers.
Greg Rosalsky of NPR’s Planet Money spotlights a new study co-authored by Prof. David Autor that examines the impact of the China Shock on Americans working in the manufacturing industry. Rosalsky notes that the research by Autor and his colleagues on the China Shock demonstrates what happens “when a bomb explodes on a community's main industry. The community doesn't just bounce back. Workers don't just shift to new sectors or move to new places. The social fabric of the community gets ripped apart. Destitution, squalor and depression set in.”
Via Separations, a startup co-founded by Shreya Dave ’16 and Brent Keller ’16 after conducting research with MIT Professor Jeffrey Grossman, has announced a $38 million Series B led by NGP ETP, reports Ron Miller for TechCrunch. “Basically, our vision is if we can decarbonize that supply chain infrastructure, then we don’t have to rely on consumers having to make a decision between the thing that they want and how to do good for the planet” says Dave.
WCVB-TV spotlights two MIT startups, True Moringa, a beauty and wellness company that uses the oil from Moringa trees grown in Ghana to directly benefit farmers in Ghana, and Sourcemap, which traces supply chains and provides transparency about where goods are stemming from. Says Kwami Williams ’12, co-founder and CEO, of his inspiration for True Moringa: “I started to ask myself, if aerospace engineers can help put a man on the Moon, then what can I do to help put more food on the table for families” in Ghana.
Mashable reporter Emmett Smith spotlights how MIT researchers have created a new toolkit for designing wearable devices that can be 3D printed. “The researchers used the kit to create sample devices, like a personal muscle monitor that uses augmented reality,” explains Smith, “plus a device for recognizing hand gestures and a bracelet for identifying distracted driving.”
Ben Armstrong, interim executive director of the MIT Industrial Performance Center, speaks with Forbes contributor Ethan Karp about the labor shortage in manufacturing and the future of the field. “We want to have companies that are really driving technology forward and forcing us to adjust our training system to be more technologically advanced,” says Armstrong. “Instead, the problem is that a lot of small and medium manufacturers are offering comparatively low-wage, low-tech jobs that are oftentimes low-skilled. So companies are adapting a lot of their operations to a lower-technology, lower-wage, lower-skill equilibrium.”
National Geographic reporter Roxanne Khamsi spotlights how Prof. Richard Braatz is working on developing continuous manufacturing processes that could help boost global vaccine availability. Khamsi notes that one feature Braatz and his colleagues are testing is using “a filter that attaches to the side of their production tanks to continuously extract vaccine material, rather than harvesting it in bulk.”
