Abstract
Code block or code marking application, removal, and replacement templates and methods for use for code blocks and code markings that are used in conjunction with the guide path, guide line, and guide tracks used by automated guidance vehicles (AGVs), which are otherwise known as autonomous guidance, automatic guidance, and automatically or autonomously guided vehicles. Guide line code blocks are typically applied to the floor of a factory, warehouse, or other facility that employs AGVs, which can sense the guide lines and/or the code blocks for purposes of maneuvering payloads while navigating through the facility. The AGV code template includes a generally planar template substrate configured with corresponding control and alignment aperture patterns formed in the template that are offset from each other. A plurality of spaced-apart code spur openings form the control and alignment aperture patterns wherein each of the openings of the control aperture pattern corresponds with an offset opening of the alignment aperture pattern and represents a code spur that is typically designated either a start, finish, on, off, or synchronization bit.
