2017 IEEE 30th International Conference on Micro Electro …, 2017•ieeexplore.ieee.orgThis paper presents the first demonstration of an untethered legged microrobot walking at
speeds greater than 5 body lengths/second. This work integrates contributions in multi-
material robot leg design and microfabrication as well as high power actuation using an
external magnetic field. The resulting 25 mg, 4 mm× 4 mm× 5 mm hexapedal robot has been
measured walking at speeds in excess of 20 mm/sec, reaching a top speed of 25.5 mm/sec
(6.4 body lengths/sec) with a calculated mechanical power to drive the legs of 0.51 mW.
