Pluto and its moons seem to be engaged in a kind of chaotic dance routine with each other. After a thorough analysis of data gathered by the Hubble Space Telescope, NASA scientists found that Nix and Hydra – two of Pluto’s five known moons – are wobbling and behaving erratically as they orbit the distant […]
Robotic Arm Has Split-Second Timing
Swiss scientists have developed a robotic arm that can catch items thrown at it with split-second accuracy. Researchers say the new invention, described in IEEE Transactions on Robotics, catches various sized objects within 5/100 of a second. The mechanized arm has three joints, a complex and sophisticated hand with four fingers, and measures about 1.5 […]
