Israeli scientists from Techion University have teamed with the College of Judea and Samaria to create a one millimeter bot that can be inserted into a patient’s bloodstream, with no miniature Rachel Welch or Stephen Boyd needed. The mini-robot is composed of a hub and tiny arms that can hold on to vessel walls even upstream, and is controllable by its operators almost indefinitely. A similar bot has been created by Kyoto University but its size is one centimeter, too large to get into the smaller spaces. What a pity that Isaac Asimov couldn’t be here to see him novelization come to fruition.
