Detection of methanol using a soft photonic crystal robot

Robots are currently employed in industrial sites and fields, including disaster rescue, medicine, security, and national defense. Conventional metal-based robots exert strong operating power due to rigid body construction with joints connected to actuators such as motors. However, they may have difficulty with flexible movements and can cause harm during malfunctions. Recently, "soft robots" made of smooth and flexible materials have emerged, but they may be more difficult to control than metal-based robots.
