Abstract: Electronic components, including a transceiver for two-way wireless communications, are carried by a freely roaming animal such as a rat. Electrodes are implanted in the brain of the animal to provide cues and rewards to the animal to achieved desired behaviors, including controlling the direction and speed of movement of the animal, and training the animal to recognize odors. The electronics can include network interface components that allow a network of the animals to work together. Sensors carried by the animal provide information to a remote base-station regarding, e.g., heading and location. Other sensors, such as a video camera, microphone, and chemical or gas detector, provide information regarding an environment of the animal. The animal can carry out missions such as searching for people buried in rubble piles, law enforcement operations, and detection of explosives, chemicals or other dangerous materials. A vehicle for deploying the animal is also provided.
