An environmentally-friendly robot that uses xenon is proposed as a solution to the Ebola crisis. It shoots out ultraviolet rays and can disinfect a room in a few minutes from any germs. The robot is derived from a character, R2D2, in Star Wars. The robot is used widely in American hospitals, but it cannot be deployed to West Africa yet.
In my opinion, I feel that this robot is really a useful invention as it saves man power and is not harmful to the environment. It can do its job better than humans. However, I believe that it cannot be sent to West Africa as it must be thoroughly checked for errors. Since it is such a new invention, errors may occur easily.
