Abstract Wireless millimeter-scale origami robots have recently been explored with great potential for biomedical applications. Existing devices usually require separate geometrical components locomotion and functions. Additionally, none of them can achieve both on-ground in-water locomotion. Here we report a magnetically actuated amphibious millirobot that integrates capabilities spinning-enabled multimodal locomotion, delivery liquid medicine, cargo transportation wireless operation. This takes full advantage the features folding/unfolding capability Kresling origami, triangulated hollow cylinder, to fulfill multifunction: its are exploited generating omnidirectional in various working environments through rolling, flipping, spinning-induced propulsion; is utilized as pumping mechanism controlled medicine; furthermore, spinning motion provides sucking targeted solid transportation. We anticipate millirobots potentially serve minimally invasive diagnoses treatments.
