The design of this ocean microplastic cleaning device is inspired by the starfish. Its overall shape mimics the contours and structure of a starfish, with a radial layout. Solar panels are distributed along each "arm" to provide clean energy for the device's operation. The top dome resembles the sensory structure of a starfish, housing various sensors and control devices for monitoring the surrounding environment and regulating the device’s operation. The spiral-shaped base, akin to the starfish's suction cups and feet, effectively absorbs and collects ocean microplastics.
