Among them, octopuses stand out by integrating camouflage, locomotion, and object manipulation seamlessly. Here, OCTOID is presented, an octopus-inspired soft robotic system that utilizes cholesteric liquid crystal elastomers (CLCEs) to combine dynamic structural color modulation with programmable, reversible shape morphing within a unified platform. By tailoring CLCE compositions derived from the same precursor chemistry, two distinct layers are fabricated: an active layer (AL) exhibiting tunable optical response and a passive layer (PL) with contrasting mechanical properties. Modular actuators assembled from symmetric and asymmetric AL/PL combinations enable diverse motion modes, equipping OCTOID to achieve adaptive camouflage, directional movement, and secure gripping. This integration of optical and mechanical programmability highlights tunable chiroptical soft materials as a versatile foundation for biomimetic multifunctional robotics, advancing possibilities in autonomous actuation and optomechanical machine design.
