Multimodal self-sustainable autonomous loco-
motions integrated into one individual system, are high-
level
intelligent
behavioral
characteristics
of
living
organisms and are the scientific hotspot of bionic soft
actuators. Here, we report a light-fueled soft actuator
with multimodal self-sustainable movements based on a
Seifert ribbon bounded by a Hopf link. The Seifert
ribbon actuator can self-sense the illumination area
adjustment, and the actuation component becomes
either a discontinuous strip-like structure or a continu-
ous
toroidal
structure,
which
can
realize
adaptive
switches between self-sustained oscillatory and rotary
motions. The two motion modes are applied to the self-
oscillatory piezoelectric generation and self-rotational
work multiplication of cargo transport, respectively. The
unique smartness of Seifert surface topology advances
the level of actuation intelligence with broad implica-
tions
for
the
adaptability,
multifunctionality,
and
autonomy of soft robots.
