Excavator Linkage Angle Determination Using A Laser Distance Meter
An excavator calibration framework comprises an excavator, a laser distance meter (LDM), and a laser reflector. The excavator comprises a linkage assembly (LA), implement, and controller. The LA comprises a boom with point B, stick coupled to point B, and four-bar linkage (4BL) including nodes D, F, G, and H (a dogbone linkage between nodes D and F). The laser reflector is disposed at node F. The nodes F, G, and the point B define an outer triangle BGF that defines with node D three inner triangles DGB, DBF, and DFG. The controller executes an iterative process including determining a node F position based on a LDM/laser reflector measurement signal, determining a node D position based on the node F position, and determining a dogbone angle BDF of DBF based on the node D position. The controller generates an actual dogbone angle based on a series of dogbone angles.
