We developed a fibrous optical actuator including photochromic molecules that are isomerized in reverse by optical energy. This actuator is expected to be ecofriendly, lightweight, small, flexible and noiseless. In this paper, we produce the prototype by diffusing β-carotene in the crystal structure of nylon-6 filament. We investigate the feasibility of the proposed actuator to apply to robots and mechatronics experimentally.
