This artist's concept shows Surrogate, a robot that could one day assist in disasters or hazardous situations such as a dangerous chemical laboratory.

Surrogate was designed and built at the Jet Propulsion Laboratory in Pasadena, California. Its components came from RoboSimian, another JPL-built robot designed for disaster relief and mitigation (see PIA19313). Surrogate rolls on a track rather than moving on its limbs.

Surrogate received support from the Defense Threat Reduction Agency and the Robotics Collaborative Technology Alliance. The California Institute of Technology manages JPL for NASA.
