Insects can locomote readily in challenging environments, such as over steep inclines and across obstacle-laden terrains, which still frustrate robots of similar size. In this work, inspired by the passive compliant properties of insect limbs, we use the insect-scale Harvard Ambulatory Microrobot and multilayer microfabrication techniques as platform to study the ability of passive mechanisms to i...
