Multifunctionality of 3D helical spinbots. a–c Time-lapsed images of the revolving spinbots for 0.2 s. a Stepping AR-3 at 1040 r.p.m. b AR-3 climbing uphill at 1040 r.p.m. and overcoming slips by frictional force. c Underwater swimming of AR-2 at 1420 r.p.m. d Concurrent swimming motions of underwater AR-2 with an orbital period of 4 s and above water AR-3 with an orbital period of 19 s at 1200 r.p.m. The dot line is a guide of AR-2 tumbling on substrate. e Orbital maneuver of the amphibious spinbot in the case of AR-2 at 1580 r.p.m.
