The Autonomous Loading System (ALS) completely automates the task of loading excavated material onto dump trucks.
The ALS robotic excavator
is capable of loading trucks at the speed of an expert
human operator, increasing productivity and improving
the safety of excavation projects.
The excavator uses two scanning LADAR rangefinders to locate
the truck, measure the soil face and detect obstacles. The
ALS software decides where to dig in the soil, where to dump
the excavated soil in the truck, and how to quickly move between
these points while detecting and stopping for obstacles. The
system modifies both its digging and dumping plans based on
soil settling detected by its sensors.
