“Advanced robots tend to be loaded with sensors that help them analyze their environment and avoid obstacles like walls and debris. One crash can break a robot’s parts and end its mission, so the sensors play an important role in planning a cautious route.
Gimball, a drone built by researchers at École Polytechnique Fédérale de Lausanne in Switzerland, doesn’t have any sensors to prevent it from damaging itself. Instead, it flies in an elastic cage and bounces wildly from obstacle to obstacle, allowing the cage to absorb the shock of each hit.”
