MIT researchers are designing a school small robotic fish that could be used to explore underwater spots difficult for humans to reach. For example, they could act as remote sensors, traveling through oil pipes or shipwrecks, or collecting environmental data. The 5 to 8-inch long prototypes, made from soft polymers, mimic real fish that swim by tensing and relaxing muscles to produce a vibration in their bodies. From MIT News Office:
"With these polymers, you can specify stiffness in different sections, rather than building a robot with discrete sections," says (mechanical engineering professor Kamal) Youcef-Toumi. "This philosophy can be used for more than just fish" - for example, in robotic prosthetic limbs...
Later this fall, the researchers plan to expand their research to more complex locomotion and test some new prototype robotic salamanders and manta rays.
"The fish were a proof of concept application, but we are hoping to apply this idea to other forms of locomotion, so the methodology will be useful for mobile robotics research - land, air and underwater - as well," said (grad student Pablo) Valdivia Y Alvarado.
A better understanding how a sperm swims its way toward an egg could help inform new treatments for male infertility. Researchers from the University of York have now come up with a mathematical formula to model how large numbers of moving sperm interact with fluid they’re swimming through. From the University: By analysing the head […]
Dr Gale Ridge is a public entomologist at the Connecticut Agricultural Experiment Station, where an average of 23 people a day call, write or visit; an increasing proportion of them aren’t inquiring about actual insects, they’re suffering from delusional parasitosis, and they’re desperate and even suicidal.
The Raspberry Pi Foundation has done outstanding work packing a fully capable desktop computer into a package the size of a deck cards—especially one that only costs $35. But if you already have a working laptop, why should you care? Oh, how much you have to learn. Besides operating well as a compact digital media hub, […]
Custom coffee vessels are the perfect piece of office flair, but it’s just a matter of time before your VOTE FOR PEDRO mug will start to lose its relevant wit. Why not have a new one every day, with whatever silly nonsense you want sticking off the sides? You can save big on your novelty […]
The Lightning port has thus far resisted the cruel fate that befell the headphone jack, and despite rumors that it may be disappearing come iPhone 8, for the present and foreseeable future, Lightning cables are a hot commodity for iPhone users. As such, we must make do in this strange time in which long, glorified […]
