An autonomous off-road vehicle (AOV) autonomously performs a pile driving operation by driving a pile into the ground at a location identified by a pile plan map. The AOV detects one or more attributes of the pile using one or more sensors during or after the pile driving operation. The AOV determines whether the one or more attributes of the pile exceed respective tolerance thresholds. The AOV performs a quality control action in response to determining that the one or more attributes of the pile exceed the respective tolerance thresholds. The one or more attributes include one or more of a location and an orientation of the pile, and the quality control action is performed in response to determining that the location or the orientation of the pile exceeds the respective tolerance threshold.

An autonomous off-road vehicle (AOV) includes a vehicle body, and a first platform and second platform configured to carry one or more piles for transport by the AOV. The first platform and second platform are coupled to opposite sides of the vehicle body. A base of each of the first platform and the second platform is angled upwards and away from the vehicle body. The AOV further includes a vehicle tool coupled to the vehicle body and configured to pick up a pile carried by the first platform or the second platform and drive the pile into ground.

An autonomous off-road vehicle (AOV) includes a vehicle body and a vehicle arm coupled to the vehicle body and including a set of prongs and a clamp extending outward from an end of the vehicle arm. A controller causes the vehicle arm to pick up a pile by: aligning the set of prongs with an end of the pile such that a first prong aligns with an opening on a first side of a web of the pile and a second prong aligns with a space on a second side of the web, inserting the set of prongs into the opening on the first side and the space on the second side, and compressing the clamp into an exterior surface of a flange of the pile such that the set of prongs are reciprocally compressed into an interior surface of the flange on either side of the web.

An assembly for a truss foundation embedment and installation machine. The machine mast has a rotary driver, target assembly, and a truss component holder. After a pair of foundation components are embedded, the truss component holder is moved to an orientation location that aligns the rotational axis of a specific tracker bearing with respect to a work point of the truss foundation. A truss cap is placed on the truss component holder and held in place while upper leg sections are sleeved over the truss cap and down onto the embedded foundation components. A hydraulic crimper is used to crimp the portions of each upper leg section that overlap with the truss cap and the embedded foundation components to unify the truss foundation.
