Abstract: An automated assembler may include an input feeder and an assembly sub-system configured to receive two or more pieces of input lumber from the input feeder. The assembly sub-system may include one or more sensors to generate sensor data associated with at least one of positions or orientations of the two or more pieces of input lumber, one or more guides configured to position at least some of the two or more pieces of input lumber in a selected orientation based on data from the one or more sensors, and one or more fastening tools configured to fasten the two or more pieces of input lumber to form an assembled product. The automated assembler may further include one or more output feed conveyors configured to receive the assembly sub-system.
