Robot David Drilling and Hammering into Concrete

Robot David Drilling and Hammering into Concrete.

David (formerly Hand-Arm System) is an anthropomorphic robot developed at DLR that features variable stiffness actuators (VSA) in all its joints. This demo shows David drilling into a block of concrete with a drill hammer. The built-in VSA enhances Davids' mechanical robustness against external impacts. This allows him to handle the impacts due to the drill hammering with relative ease.
