- Imagine if there were a robotic fish that filtered microplastic particles out of the water as it swam.
- The robot swims by flapping its tail, holding its mouth wide open to collect water (and microplastics) in an internal cavity as it does so.
- Once that cavity is full, the bot closes its mouth, opens its louvre-like gill flaps, and pushes the water out through those flaps by raising the floor of the cavity.
