Abstract: A method is performed to immobilize and radio-isolate a robotic device. The method includes steps of storing ingredients that when mixed together create a foam that hardens to 50 percent to 75 percent of ultimate physical characteristics in less than 90 seconds after being sprayed; containing metal particulates for mixing prior to spraying; piping the ingredients and metal particulates to a nozzle so that they mix together to form a metal-foam mixture when sprayed from the nozzle; and spraying the metal-foam mixture on the robotic device. An optional spray component is liquid glue that is piped to mix with the foam ingredients and metal particulates prior to spraying.
