Autonomous construction vehicles By Thomas Wilmet

Most engines of the kind are actually only partially autonomous excavators, as an operator is so far still needed to control the excavator's boom. For example, the PC210LCi-10 intelligent model from the Japanese manufacturer Komatsu one of the industry leader, relies on a factory-integrated 3D GNSS machine control and guidance system but is

IMPLEMENTATION OF A VIRTUAL AUTONOMOUS EXCAVATOR

NAV is a system of robotic components that installs easily into any excavator, converting it from manual to robotic control. Since most modern excavators are controlled by-wire, Nav leverages the excavator's existing CAN Bus system to direct vehicle functions. This way, Nav is able to control the undercarriage, boom, bucket, and monitor real-time vehicle health indicators.
