Electronic components, including a transceiver (220) for two-way wireless communications, are carried by a freely roaming animal (190) 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. Network interface components (265) allow a network of the animals to work together. Sensors (225, 230, 235, 245, 255, 260) carried by the animal provide information to a remote base station regarding, e.g., heading and location. Chemical or gas sensors, along with a video camera and a microphone provide information regarding an environment of the animal. The animal can search for people buried in rubble piles, and detect explosives, chemicals or other dangerous materials. A vehicle (500) for deploying the animal is also provided.
