If you tell Justin to "dance like in Pulp Fiction," the robot will immediately start performing like John Travolta in the famous movie scene.

History

Led by Prof. Alin Albu-Schäffer, the Institute of Robotics and Mechatronics, part of the German Aerospace Center (DLR), has been developing lightweight robot arms and hands since 1995. In 2006, researchers combined two arms, hands, and a torso to build the first Justin upper body, mounted on a table. In 2008, a wheeled base was added, and Rollin' Justin made its debut. In 2012, the current system was equipped with an improved control system for the mobile base and an updated computing platform. In a 2017 teleoperation experiment, an astronaut on board the International Space Station remotely operated Rollin' Justin in a simulated Mars environment constructed at a DLR facility in Oberpfaffenhofen, near Munich.
