Once that cavity is full, the robot closes itsmouth,opens its gill flaps (鳃盖), and pushes the water out through those flaps by raising thefloor of the cavity. A fine net attached to the gill flaps allows the water to pass through, butcatches the microplastic.In its current physical form, the 50-cm-long Robo-fish collects microplastic as small as 2millimeters.It also wears onboard sensors to monitor underwater environment, plus it uses an IMU(inertial measurement unit) device to track its movements within the water.That said future style could catch much smaller microplastic. Other possible improvementsinclude a faster,more dynamic body shape,a more powerful tail, and the ability to swimautonomously-the current type works by hard-wired remote control.B.By selecting the best concept of robots.A.
