What it is
Valkyrie (R5) is NASA Johnson Space Center's first bipedal humanoid, built in 15 months for the 2013 DARPA Robotics Challenge Trials. The 1.88 m, 136 kg robot has 44 degrees of freedom, series-elastic actuators, a Multisense SL perception head and a 1.8 kWh battery for about an hour of operation. NASA later used it for Space Robotics Challenge research with IHMC walking software.
