Drones are going to be used to do many things for us in the future. That includes delivery packages, helping in search & rescue missions, and even holding umbrellas. As it turns out, someone has already developed parasols carried by drones. This particular drone can fly for 20 minutes on a full charge. It can even keep you cool on muggy days.
Asahi Power Service is planning to waterproof these for use in the rain. For now, these will be sold in private areas like golf courses.
