A small yellow robot developed by Chinese technicians is safeguarding coral reefs in the South China Sea.
When it finds crown-of-thorns starfish preying on coral polyps, the robot rushes and kills them.
The 45-cm-long, 29-cmwide and 22-cm-tall robot weighs less than 10 kilograms. Equipped with four high-power thrusters, it moves freely like a skilled diver.
