A vehicle designed to detect, identify, and establish the location of portable objects in a building or structural space, such as portable medical equipment in a hospital environment, that move from place to place as they are used. The vehicle system provides for automatic detection and correlation of the objects' locations, while the vehicle is propelled within the structural environment, using passive radio frequency transponder technology to detect the presence of tagged objects and tagged fixed locations, basic identification of the object or spatial location replying to the interrogation, and time-stamped correlation of objects and spatial locations. The transmitters and antennae are mounted in the vehicle and are protected from environmental hazards such as pressure washing. An integrated microprocessor performs the requisite algorithms needed to process the reply from one or more Radio Frequency IDentification (RFID) tags, correlates the data and transmits the data, via a wireless RF modem mounted to the vehicle, to a central modem for storage and processing. Rechargeable dry cell or gel batteries power the vehicle's electronics for 24 hours or more, and the vehicle is equipped with an onboard battery charger that can be plugged into a standard AC power socket.
