Robotic Venus Flytraps

Venus Flytrap Robots

These robots are designed to hunt bugs—-just like Venus Flytraps.

One prototype, developed in South Korea, uses a shape-memory metal spring as the basis for the shutting mechanism. The other, created in Maine, uses artificial muscles made of a gold nanomaterial.

At the moment, the bugs can’t be turned into energy to power the device, but we already have robots that can successfully digest insects. Put these two technologies together and we have a self-powered, bug-consuming robot.
