Researchers at the Swiss Federal Institute of Technology in Lausanne have constructed a vampire bat drone that is inspired by how such bats use the tips of their wings like legs when traversing the ground. By being able to both walk and fly, the DALER (Deployable Air-Land Exploration Robot) is able to expand the terrains and areas it can access.
The versatility of movement offered by the vampire bat drone means that it could be a supremely useful tool in the realm of disaster relief, and could be used to locate survivors and explore unstable locations. The drone could be remotely deployed, fly to damaged areas and walk around on the ground if needed to locate victims. This would enable human rescue teams to focus their efforts where they will count.
