Defender is an ideal ROV for bomb technicians with special features includinch chem-bio wash down capability, allowing it to be used in potential chemical/biological/radiological (CBR) situations. The robot, from Allen-Vanguard, and all of its devices are configured as a computer network so operators simply "plug and play," driving it with spread spectrum radio frequency telemetry from a PC-based console at the incident control point. Defender has five fitted cameras, and the user can view two flicker-free images on a screen simultaneously or switch between all five.
