DARPA had a challenge for different companies to build a super hero robot which would one day save a life. NASA’s robot Valkyrie (ugly name) looks very much like IronMan version 0.1. The challenge created by DARPA involves tasks like walking over uneven terrain, climbing a ladder, using tools, and driving. This means that Valkyrie has to be capable of operating in the same spaces that a person would operate in, under the control of humans who have only minimal training with robots, which is why the robot’s design is based on a human form.
