We have all seen insects find their way back home all the time. Researchers are inspired by those to come up with autonomous navigation for tiny, lightweight robots. This approach allows robots to come back home without too much computing power.
Researchers were inspired by how ants “visually recognize their environment and combine it with counting their steps” in order to get back home.
