Abstract: An autonomous assembly that includes a gantry subassembly, a carrier subassembly movably mounted on the gantry subassembly, a tool actuation subassembly mounted on the carrier subassembly, and an autonomous control system including a perception subsystem, a motion planning subsystem, and a motion control subsystem. The gantry subassembly includes a bridge member for laterally spanning a selected section of a work site and a gantry drive system for effecting travel of the gantry subassembly along a first path, generally in a longitudinally along the length of the selected portion of a work site. The carrier subassembly includes a carriage and a carriage drive system for effecting travel of the carriage along a second path, generally laterally along the bridge member.

Abstract: The present invention is directed toward a cam assembly comprising a cam, a drive shaft and an adjustable screw. The cam includes a first side, a second side opposite the first side, an outer perimeter and a thickness between the first and second sides. The cam further has a first elongated bore through the first and second sides and the thickness of the cam, wherein the first elongated bore has a length radially oriented in the cam and a first end and a second end. The cam further has an elongated threaded hole extending from the outer perimeter to and being in communication with the first elongated bore. The drive shaft extends through the first elongated bore. The adjustment screw is within the elongated threaded hole and is engaged with the drive shaft, wherein the cam assembly is constructed and arranged such the drive shaft can be adjustably positioned and fixedly secured relative to the cam at a plurality of positions along the length of the first elongated bore.
