Tiny, soft robot with multi-legs paves the way for drug delivery in the human body 

Prof. WANG Zuankai (MNE), Dr. SHEN Yajing (BME), PhD students LU Haojian and YANG Yuanyuan (BME), research associate Dr. ZHANG Mei (MNE), and their collaborators have developed a novel tiny, soft robot with caterpillar-like legs capable of carrying heavy loads and adaptable to adverse environments. The mini delivery-robot could pave the way for medical technology advances, such as drug delivery in the human body. The highly agile milli-robot is able to leap over 10 times its leg length. Thanks to its multi-leg design, which helps reduce friction significantly, the robot can move efficiently inside surfaces in the body lined with, or entirely immersed in, body fluids, such as blood or mucus. Laboratory tests show that it can carry a load 100 times its own weight, which is comparable to a human easily lifting a 26-seat minibus. The aim of the research team in the next two to three years is to create a biodegradable robot that will decompose naturally after completing its drug delivery mission.

The research findings have been published in the latest issue of the scientific journal Nature Communications in a paper titled “A Bio-inspired Multilegged Soft Millirobot that Functions in Both Dry and Wet Conditions”.
