Many members of Team RoboSimian and a few guests gather with competition hardware at a "Meet the Robots" event during the DARPA Robotics Challenge Finals in Pomona, California, on June 6, 2015. The RoboSimian team at JPL is collaborating with partners at the University of California, Santa Barbara, and the California Institute of Technology in Pasadena. Caltech manages JPL for NASA. http://photojournal.jpl.nasa.gov/catalog/PIA19329

Using a cordless power drill, RoboSimian cuts a hole into a panel of drywall to complete one of the tasks in the DARPA Robotics Challenge Finals in Pomona, California. This image was taken on June 6, 2015. http://photojournal.jpl.nasa.gov/catalog/PIA19326

The spindly appearance of JPL's RoboSimian was somewhat unique among competitors in the DARPA Robotics Challenge Finals in Pomona, California, as most were bipedal walkers. This image was taken on June 5, 2015. http://photojournal.jpl.nasa.gov/catalog/PIA19328

This artist concept depicts RoboSimian, a disaster-relief and -mitigation robot, grasping the rung of a ladder. RoboSimian is an ape-like robot designed and built at NASA Jet Propulsion Laboratory, Pasadena, Calif.

This image was taken on June 6, 2015 at the DARPA Robotics Challenge in Pomona, California. Following each competition run, spectators at the event were able to get a close-up look at the robot competitors and meet the teams who built them. http://photojournal.jpl.nasa.gov/catalog/PIA19327

Engineers from NASA Jet Propulsion Laboratory carry RoboSimian, a robot developed at JPL, at the DARPA Robotics Challenge Trials in Florida in December 2013.

RoboSimian, a limbed robot developed by engineers at NASA Jet Propulsion Laboratory in Pasadena, California, competed in the DARPA Robotics Challenge DRC Trials in Florida in December 2013.

RoboSimian and Surrogate are robots that were designed and built at NASA Jet Propulsion Laboratory in Pasadena, California.

This photograph shows RoboSimian, a disaster-relief and -mitigation robot, under construction in a lab at NASA Jet Propulsion Laboratory, Pasadena, Calif.

Robotics researchers at NASA Jet Propulsion Laboratory in Pasadena, California, stand with robots RoboSimian and Surrogate, both built at JPL.

Limbed robot RoboSimian was developed at NASA Jet Propulsion Laboratory, seen here with Brett Kennedy, supervisor of the JPL Robotic Vehicles and Manipulators Group, and Chuck Bergh, a senior engineer in JPL Robotic Hardware Systems Group.

RoboSimian is an ape-like robot that moves around on four limbs designed. It was designed and built at NASA Jet Propulsion Laboratory in Pasadena, California.

This artist's concept shows RoboSimian, a robot intended to assist with disaster relief and mitigation. RoboSimian is an ape-like robot that moves around on four limbs. It was designed and built at the Jet Propulsion Laboratory in Pasadena, California. It will compete in the 2015 DARPA Robotics Challenge Finals. To get the robot in shape for the contest, researchers at JPL are collaborating with partners at University of California, Santa Barbara, and the California Institute of Technology. http://photojournal.jpl.nasa.gov/catalog/PIA19313

This artist's rendering shows a concept for a robot called AquaSimian that would assist with hazardous situations underwater. The concept is derived from RoboSimian, a land-based robot designed and built at the Jet Propulsion Laboratory in Pasadena, California. RoboSimian is shown in PIA19313. http://photojournal.jpl.nasa.gov/catalog/PIA19315

Known as Clyde, RoboSimian is an an ape-like robot designed and built at Jet Propulsion Laboratory, Pasadena, Ca. The robot is four-footed but can also stand on two feet. It has four general-purpose limbs and hands capable of mobility and manipulation.

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. http://photojournal.jpl.nasa.gov/catalog/PIA19314
