Abstract
A machine, including a bucket linkage that defines dig block constraints, including: a reach inside and outside limits; swing first and second limits; and a depth limit. Sensors can be positioned on the machine to count dig passes. One or more memory devices have instructions that when executed by one or more processors cause the processors to: generate an excavation plan, including: determining a number of elevations; determining a number of rings in each elevation; and determining a number of sectors in each ring; and direct the excavator to perform dig passes in order to sequentially excavate each sector, wherein the sectors in each elevation are excavated from the reach outside limit to the reach inside limit and from the swing first limit to the swing second limit; wherein the system moves to the next sector when a threshold number of dig passes is reached.
