Rollin Justin Helmets

Justin (also known as Rollin' Justin) is an autonomous and programmable humanoid robot with two arms, developed by the German Aerospace Center (DLR) at the Institute of Robotics and Mechatronics, located in Wessling, Germany.[1][2] Introduced in 2009, this wireless robot is controllable through telepresence, a type of technology that allows a person to feel as if he or she were present from a location other than his or her true location.
Justin is intended to be mounted on its own satellite, maneuver in orbit, and repair other satellites. However, it can also be used on Earth to perform simple tasks.[3] The European Space Agency (ESA) plans to have astronauts aboard the International Space Station teleoperating Justin by 2014.[4] Rollin' Justin has some variations depending on its intended purpose. For example, some versions of Justin may not have wheels. DLR also recently created Agile Justin—an upgraded version of Rollin’ Justin, and TORO—which is similar to Rollin' Justin, except with legs instead of wheels.[5]

Justin's upper body has 43 total controllable degrees of freedom, which is the number of independent factors that define the robot's configuration.
