This robot is known as David, formerly Hand Arm System, and is an anthropomorphic robot developed at DLR that features variable stiffness actuators (VSA) in all its joints.

This demo, below, shows David drilling into a block of concrete with a drill hammer. The built-in VSA enhances David's mechanical robustness against external impacts. This allows him to handle the impacts due to drill hammering with relative ease. The drilling tasks shown requires both precise positioning of the tool centre point and vibration damping.

The robot features end effector tracking with its head. It uses both its arms to complete complex tasks. You can have a look at the video below to learn more about the drilling robot.
