Abstract
A closed-loop feedback-control system for a screw anchor driving machine that uses a controller such as a programmable logic controller (PLC) and an array of sensors providing real-time data to control an automated screw anchor driving operation relying on a rotary driver, a crowd motor applying downforce to the rotary driver and a tool driver extending a tool through the rotary driver and screw anchor to drive screw anchors to a target depth. The tool driver is independently controllable to advance the tool at a different feed and speed than the rotary driver to respond to underground conditions encountered during driving.
