This invention pertains to the development of a drone that can pour a variety of chemical agents such as oxidizers, silica gelling agents, enzymes, and neutralizers onto areas contaminated with chemical and biological weapons of mass destruction. These decontaminants are known to be effective at destroying both chemical and biological weapons of mass destruction simultaneously. The use of a drone to destroy the chemical and biological weapons of mass destruction is highly beneficial since it allows the exposed toxic areas to be remotely decontaminated without the presence of humans. Some of these methods of decontamination are non-toxic and environmentally friendly so it can also be used to pour or spray these agents on humans that are exposed to chemical and biological weapons of mass destruction to safely destroy these agents. The drone will be designed as a transformable robot which can lift the container containing the decontaminant in the ground mode and fly over to the contaminated site which is either outdoors or indoors using its flight mode. The transformable robot would pour the different decontaminant solutions on the contaminated areas or contaminated humans to simultaneously destroy chemical and biological warfare agents. They can also be used to decontaminate chemical or biological weapons of mass destruction found separately at sites.
