Students of Tyndall Elementary School observe a Quad-legged Unmanned Ground Vehicle, nicknamed a robot dog, at the school outside of Tyndall Air Force Base, Florida, Oct. 13, 2021. The Q-UGVs are used to patrol remote areas of Tyndall which may be more difficult or dangerous for Defenders to access, allowing for a more secure and safer installation.
