Abstract: An automated driving and assembly machine for driving foundation components, such as screw anchors, and for assembling foundations, such as truss foundations, using the driven screw anchors. The machine has a rotary driver and a hydraulic drilling tool. Sensors monitoring hydraulic pressure at the drilling tool will take incremental pressure readings during a driving operation. If the readings become clustered around a relative maximum, the controller will pause the driving operation and begin a drill stall mitigation sub-routine. This may involve retracting the drill and then hammering and releasing pressurized air to clear the stall. Clearance of the stall may also be derived by the controller from pressure readings.
