Bioinspiration

CNN visits the lab of Prof. Kevin Chen to learn more about his group’s work developing a bee-like robot that can flap its wings up to 400 times a second and flip and hover, and a grasshopper-inspired robot that can hop 20 centimeters into the air in terrains ranging from grass to ice. Chen and his colleagues hope the insect-inspired robots could one day help with tasks like artificial pollination or search and rescue operations. Insects have “evolved for millions of years. There’s a lot to be learned from insect motion, behavior and structure," Chen explains.

Prof. Giovanni Traverso speaks with WCVB about his research developing an ingestible robotic capsule capable of delivering an injection directly within the stomach. “Fifty percent of the population don’t take medication as prescribed. That’s incredible,” says Traverso. “So, if we can make a little dent, or hopefully a bigger dent, I think we can help a lot of folks out there.”  

Researchers at MIT have developed a “small, hopping robot designed to traverse challenging environments,” reports Emmett Smith for Mashable. “The robot utilizes a spring-loaded leg for propulsion and incorporates flapping wing modules for stability and control,” explains Smith. “This design enables movement across diverse surfaces and the ability to carry loads exceeding its own weight.” 

Materials World reporter Sarah Morgan spotlights how MIT researchers have “combined the waterproof stickiness of mussel-inspired polymers with the germ-fighting properties of mucus-derived proteins, mucins, to form a cross-linking gel that strongly adheres to surfaces.” The new adhesive could be used to coat medical implants to prevent infection and bacteria build-up. Postdoc George Degen explains: “We demonstrate adhesion to wet tissue and metal-oxide surfaces, important substrates for biomedical applications. Moreover, our mucin-derived hydrogels discourage the formation of bacterial biofilms, raising the possibility of antifouling coatings.” 

Graduate student Yi-Hsuan (Nemo) Hsiao and City University of Hong Kong Prof. Pakpong Chirarattananon have developed a “hopping robot that can leap over tall obstacles and jump across slanted or uneven surfaces, while using far less energy than an aerial robot,” writes Andrew Corselli for Tech Briefs Magazine. “One of the biggest challenges is our robot is still connected with a power cable,” explains Hsiao. “I think going into power autonomy — which means we carry a battery and a sensor onboard — will be the next step. And this robot has really opened the opportunities for us to do that.”

MIT researchers have developed a method to grow artificial muscle tissue that twitches and flexes in multiple, coordinated directions, and could be useful for building “biohybrid” robots, reports Andrew Corselli for Tech Briefs. Prof. Ritu Raman explains that her lab is focused on creating “artificial muscle tissues that can be used to understand and treat muscle diseases that impact healthy human mobility,” and making “safe muscle-powered robots that can perform complex tasks in dangerous environments that are not suitable for humans.”

MIT researchers have developed a new method to grow artificial muscles for soft robots that can move in multiple directions, mimicking the iris of an eye, reports Mrigakshi Dixit for Interesting Engineering. The researchers developed a new technique called “stamping” to create “an artificial iris-like structure,” Dixit explains. “For this, they 3D-printed a tiny stamp, patterned with microscopic grooves. This stamp is then pressed into a soft hydrogel to create a blueprint for muscle growth.”

MIT researchers have developed a technique to use a damage suppressing protein called “Dsup” to help protect cancer patients from the side effects of radiation therapy, writes Shane Galvin for The New York Post. “Scientists, encouraged by this remarkable discovery, believe they can create an upgraded version of Dsup which can be used to radiation-proof human cells without any unwanted drawbacks,” writes Galvin. “They also believe that the protein could be used by astronauts to prevent space-related radiation [damage].” 

Researchers at MIT and elsewhere have found that a protein developed by tardigrades could be used to help protect cancer patients from the side effects of radiation therapy, reports Ed Cara for Gizmodo. “The findings could someday lead to an invaluable add-on treatment for many cancer patients,” writes Cara. He adds that the new technique “could even possibly be used to protect astronauts from space-related radiation or to protect cancer patients from other sources of treatment-induced DNA damage, such as chemotherapy drugs.”

According to a new study co-authored by researchers at MIT, harnessing the damage suppressor protein found in tardigrades, a microscopic organism known for its resilience, could help ease the impacts of radiation therapy on cancer patients. “The Dsup protein, which binds directly to DNA and reduces radiation-induced strand breaks, immediately struck us as a promising tool to mitigate normal tissue injury during radiotherapy,” Prof. Giovanni Traverso explains to Corinna Singleman of Genetic Engineering & Biotechnology News. 

In this interview (in Spanish), graduate students Suhan Kim and Yi-Hsuan (Nemo) Hsiao speak with Telemundo correspondent Miriam Arias about their work developing insect-sized robots to assist with agricultural needs. “There might be one year where you have a lot of bees in the field that help you pollinate everything. Maybe the next year, it might be affected by the temperature or something [and] you just don’t have enough bees to help you do so,” explains Hsiao. 

Graduate students Suhan Kim and Yi-Hsuan (Nemo) Hsiao speak with Tech Briefs reporter Andrew Corselli about their work developing insect-sized robots capable of artificial pollination. “Typical drones use electromagnetic motors plus propellers. But, our system is a little different in that we are primarily using an artificial muscle,” explains Kim. 

Researchers from MIT and elsewhere have develop insect-sized robots that could one day be used to help with farming practices like artificial pollination, reports Alice Rizzo for Reuters. "These type of robots will open up a very new type of use case," says graduate student Suhan Kim. "We can start thinking of using our robot, if it works well, for tools like indoor farming."

Prof. Giovanni Traverso speaks with the Nature Podcast hosts Benjamin Thompson and Emily Bates about his work developing an ingestible capsule capable of delivering drugs directly into lining of the GI tract. “Part of the work that we did was really defining how much force needs to be applied so that that jet can go through the tissue,” says Traverso. “But not only go through the initial part of the tissue, what we wanted to understand for each part of the GI tract was exactly how much pressure is required to essentially deposit some amount of drug under the surface of the tissue.” 

Researchers at MIT have developed an insect-like, flying robot capable of performing acrobatic maneuvers and hovering in the air for up to 15 minutes without failing, reports Alex Wilkins for New Scientist. “By having a hugely increased [flying] lifetime, we were able to work on the controller parts so that the robot can achieve precise trajectory tracking, plus aggressive maneuvers like somersaults,” says graduate student Suhan Kim.
