An end effector having a platform and a motor coupled to the platform for driving a drilling member. A motor housing is coupled to the platform and includes a plurality of photogrammetry targets secured thereto. The photogrammetry targets are oriented so as to be readily detectable by a photogrammetry sensor for determining the orientation of the end effector and corresponding drilling member. A pressure foot member and pneumatic cylinders are operably coupled to the platform such that the pneumatic cylinders maintain a constant pressure upon the pressure foot member to provide material clamp up. A depth control device is also provided for accurately controlling the depth of the drilling member and preventing further drilling.
