Hard drives are about to get supercharged
HAMR and MAMR are a pair of new methods for writing data to hard drives that could boost capacity as high as 60TB per drive, or beyond.
Harvard shrank its insect-inspired microrobot to the size of a penny
Harvard researchers have made the tiny Harvard Ambulatory Microrobot (HAMR) even tinier. The next-gen HAMR-JR is one of the smallest and fastest microrobots to date.
Harvard's tiny robot can swim and walk underwater
Harvard is developing a knack for tiny amphibious robots. Its researchers have upgraded the Harvard Ambulatory Microbot (HAMR) with the ability to swim and walk underwater, in addition to walking on land. Its foot pads use surface tension and related buoyancy to float on the water, while electrowetting (reducing the contact angle between a material and a water surface under a voltage) helps it break through the water and walk on the ground at the bottom. Its tiny size and 1.65-gram weight play a crucial role -- significantly bigger and it would be hard for the robot to stay above-water.
