AES: Autonomous Excavator System for Real-World and Hazardous Environments
[article]
2020
arXiv
pre-print
Preserved Fulltext
Operating excavators in a real-world environment can be challenging due to extreme conditions and rock sliding, ground collapse, or exceeding dust. ...
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. ...
Our autonomous excavator (AES) is the first unmanned excavator system that has been deployed in real world scenarios and used by manufacturers of heavy machinery and the construction industry. ...
