| Computing Platform | Valkyrie is entirely electrically powered, and its design is built around series-elastic actuation rather than stiff position control: the arms carry five series-elastic rotary actuators and two linear actuators, the hands use six finger and thumb actuators, the upper legs carry five series-elastic rotary actuators with two more in the ankles, and the torso carries five of its own. Power comes from a swappable 1.8 kWh dual-voltage battery, which matters because a robot working in a damaged facility cannot be tethered, and NASA notes the robot is covered in foam and soft fabric as part of making it safe around people. Two generations of capability sit behind it: NASA describes Valkyrie as designed to operate in degraded or damaged human-engineered environments, and it is the successor in spirit to Robonaut 2, which flew to the International Space Station in 2011. NASA's stated purpose for the platform is the problem of facilities built for people to run with levers, switches, dials and doors where no people are present because the site is uncrewed or hazardous, and eventually the upkeep of a Martian base while astronauts are away. | - |
| Sensors | A Carnegie Robotics Multisense SL sensor in the head, secondary head cameras, torso cameras, shin cameras, knee lidars and six-axis force-torque sensors in the feet, giving the robot vision, depth, mapping and ground contact force sensing. | - |
