  Excavators are widely used for material-handling applications in unstructured
environments, including mining and construction. The size of the global market
of excavators is 44.12 Billion USD in 2018 and is predicted to grow to 63.14
Billion USD by 2026. Operating excavators in a real-world environment can be
challenging due to extreme conditions and rock sliding, ground collapse, or
exceeding dust. Multiple fatalities and injuries occur each year during
excavations. An autonomous excavator that can substitute human operators in
these hazardous environments would substantially lower the number of injuries
and can improve the overall productivity.
