Standing at 6 feet 2 inches (188 centimeters) tall and weighing 300 pounds (136 kilograms), NASA's humanoid robot Valkyrie is an imposing figure. Valkyrie, named after a female figure in Norse mythology and being tested at the Johnson Space Center in Houston, Texas, is designed to operate in "degraded or damaged human-engineered environments," like areas hit by natural disasters, according to NASA. A humanoid robot resembles a person, typically with a torso, head, two arms and two legs.
