Tiny soft robot with multilegs paves way for drugs delivery in human body

Around the world, there has been research about developing soft milli-robots. But the CityU's new design with multi-legs helps reduce friction significantly, so that the robot can move efficiently inside surfaces within the body lined with, or entirely immersed in, body fluids such as blood or mucus. The research findings have been published in the latest issue of the scientific journal Nature Communications, titled "A Bio-inspired Multilegged Soft Millirobot that Functions in Both Dry and Wet Conditions." What makes this milli-robot stand out is its hundreds of less than 1 mm long pointed legs that looks like short tiny hair. This unique design was not a random choice.
