Valkyrie Helmets

The Valkyrie robotic platform was originally designed and built in 2013 to carry out search and rescue missions inline with the DARPA Robotics Challenge. After a series of electro-mechanical upgrades and a software partnership with IHMC, the Valkyrie platform is now a core robotic platform in the NASA Space Robotics Challenge.

The Valkyrie robot measures about 6 feet in height and weighs 290 pounds. Valkyrie is a 32 degree of freedom (DOF) walking robot featuring two 6 DOF legs, two 7 DOF arms, a 3 DOF neck, and a 3 DOF waist. Valkyrie utilizes the MultiSense SL in its head, anterior hazard cameras, multiple LORD MicroStrain IMU sensors, and ATI Multi-Axis Force/Torque sensors.

While NASA's official position is that Valkyrie is a genderless humanoid (as is Robonaut), the robot does have some features that we would call unmistakably female. For example, there's the name of the robot. “Valkyrie” (the roboticists call it “Val” for short) refers to the female figures in Norse mythology who decided which warriors fought valiantly enough in battle to be taken to Valhalla when they died.[source: http://spectrum.ieee.org/automaton/robotics/military-robots/nasa-jsc-unveils-valkyrie-drc-robot]
