Isaac Asimov Would Have Loved This Robot Story

Have you read Isaac Asimov’s Fantastic Voyage? It is a story about shrinking a submarine and crew to microscopic size to insert them into a scientist’s bloodstream to travel to the brain to dissolve a blood clot. That was fantasy. Now for a reality that Asimov would have enjoyed! Researchers at the University of Pennsylvania and the University of Michigan recently described their invention of a sub-millimetre-sized robot no bigger than a grain of

Grain-of-Salt Microrobot Developed for Medical Use

A team of scientists from the University of Pennsylvania and the University of Michigan has developed a groundbreaking sub-millimeter robot, smaller than a grain of salt, that can move autonomously through fluid environments and process information using its onboard computer and sensors. The research, published in Science Robotics, represents a significant leap forward in robotics, marking the creation of the first microrobot capable of sensing,…
