Coral Crab

The Coral Crab uses its mouth to suck up the bird poo which lands on seaweed, helping the coral grow stronger. When it gets to the reef it opens a hatch in its stomach and drops it. It's got cameras for eyes, propellers on the pincers and lights to warn off predators.

Thank you for sending in your invention Jessie, Sofia and Georgie! What an inventive solution to help protect the invaluable corals in our oceans. The diagram is very clear and well planned out. It's great that you have chosen the robot to be in a crab form, so it blends into its environment. I thought the added propellors on the legs of the crab were a great touch and will allow the Coral Crab to access harder parts of the coral. Brilliant work!
