We create a thermo/optical drive type flexible track wireless controlled actuator that can realize multiple energy conversion on large slopes and alternate front drive and rear drive. Complex actuators with multiple joints can be constructed by structural design
which has normous potential in multi-scene driven mode and intelligent energy-harvesting system.
Artificial soft actuators
featured with non-equilibrium internal circumstance and fast
programmable shape transformations
have attracted strong research interest recently due to their flexibility
highly controllable
and designability. However
wireless soft actuators
achieving the locomotion on different large slopes with multiple energy conversion
have been rarely reported. Herein
we create a asymmetric bilayer strategy to construct autonomous soft crawler
via
“breathing” moisture to motivate the mechanical deformation. The soft crawlers present conspicuous performances including periodic tumbler locomotion predicted
via
improved Timoshenko’s equation
multiple reversible shape-morphing (circle
helix
despiralization
etc
.) determined by their fiber orientation
controlled drive mode (front drive and rear drive) and rapid climb speed (4.76 cm/min) at wide slope angles. Through architecture design
they can be series-wound or shunt-wound to construct multi-joint complex actuators. Besides climbing
a intelligent soft ring-pull with admirable cycle performance for preventing overheating or something untouchable
has been proposed. The soft crawlers also realize multiple energy conversion to be actuated by light irradiation. We envision that this soft crawler system has an enormous potential in intelligent machine
microscopic diagnosis and treatment
biosensing
energy harvesting and conversion.
