Dragonfly Robot Signals Aquatic Environmental Disasters | IE – Interesting Engineering

Duke University engineers have developed an electronics-free and autonomous soft robot that is shaped like a dragonfly. Called DraBot, the robot skims across water to signal environmental changes such as rising pH levels, temperature, or oil spills. 
DraBot, as the small 2.2-inch long and 1.4-inch wingspan robot is called, is still in its proof of concept stages but it could prove to be the future environmental mascot we’ve all been waiting for.
