Shameless plug - here is something we did about 10 years ago with custom drones we built at the time (when drones were not commercially available as much as they are today) We basically implemented a battery swapping station and kept a lab-scale surveillance mission running for 3+ hours for UAVs. Ground vehicles were too small to be battery swapped (and we didn't care about them enough as they wre doing more or less random moves). https://drive.google.com/file/d/0B0tCZKAh4H5cdm9nRkJfTFFsTG8/view?usp=sharing&resourcekey=0-OJ7xCwvrarnFgr8cUG-o4A https://drive.google.com/file/d/0B0tCZKAh4H5cdm9nRkJfTFFsTG8...
