DraBot: A Color-Changing Robot Dragonfly That Detects Pollution

Scientists at Duke University have created a small robot called DraBot that looks and moves like a dragonfly. It can fly over water and detect environmental problems like oil spills, high acidity, and temperature changes. The robot is soft, uses no electronics, and moves using air pressure.

DraBot has tiny tubes in its wings. Air flows through these tubes to move the wings and control its direction. Special balloon-like parts help it turn left, right, or go straight.

What makes DraBot special is that it reacts to pollution. Its wings are coated with hydrogel, a smart material. If the water is too acidic, the wings stick together, and the robot flies in circles, showing where the pollution is. When the water becomes normal again, the wings separate, and DraBot flies straight.

Under its wings are sponges that change color. If DraBot touches oil, the sponges soak it up and turn a different color. If the water is too hot, the color changes again.

DraBot is still being tested, but one day, it could help scientists protect water, oceans, and marine life by finding problems early and warning us.
