Abstract: A method and apparatus for applying sealant. The apparatus may comprise a sealant flow control system. The sealant flow control system may be configured to engage a nozzle of a sealant container to reduce a flow of sealant from the nozzle.

Abstract: A robot includes an actuator assembly, first and second parallel telescoping lead screw assemblies cantilevered from the actuator assembly, and an end effector supported by ends of the lead screw assemblies. The actuator assembly causes each lead screw assembly to independently deploy and retract.

Abstract: Methods are disclosed for producing a hole in a work-piece having first and second layers of material. The first layer of material contains a full-sized hole through the first layer of material. The first layer of material is positioned adjacent the second layer of material. An orbital drill is secured to the first layer of material to position a cutting tool of the drill within the through-hole. During operation, when the cutting tool is used to cut a hole in the second layer of material, the alignment keeps the orbital drill stationary.

Abstract: Embodiments of the disclosure provide a drill bit including a drill bit body having a central axis. A first cutting edge is disposed on the drill bit body at a first radial distance from the central axis as measured within a plane normal to the central axis. And a second cutting edge is disposed on the drill bit body at a second radial distance from the central axis as measured from within the plane. The first radial distance is less than the second radial distance.

Abstract: A method of using a drilling end effector includes providing a drilling end effector having a plurality of photogrammetry targets secured thereto. The positional orientation of the drilling end effector along six degrees of freedom is detected using a photogrammetry sensor to determine the orientation of the plurality of photogrammetry targets and outputting a position signal to a controller. The drilling end effector is robotically manipulated adjacent to a part to be drilled in response to the position signal to accurately position a drill bit relative to the part to be drilled. The part is then drilled.

Abstract: 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.
