Swing Trajectory Control for Large Excavators
There is a strong push within the mining sector to automate equipment such as large excavators. A challenging problem is the control of motion on high inertia degrees of freedom where the actuators are constrained in the power they can deliver to and extract from the system and the machine’s underlying control system sits between the automation system and the actuators. The swing motion of an e...
متن کاملDeveloping Plans for Robotic Excavators
We would like a robot excavator that is able to excavate a volume of soil according to specification. To this end we have developed a general method that can be used to provide prescriptions as to where and how to dig for a variety of excavator configurations and tasks. This paper presents simulation results of a front-end loader performing a loading task. In addition, preliminary results from ...

متن کاملSimulation Techniques for Improving the Fuel Efficiency of Hydraulic Excavators
Simulation techniques to reduce the fuel consumption in hydraulic excavators are presented in three categories: first, a strongly non-linear dynamic simulation technique for a coupling system with a non-linear hydraulic system and a linkage system; second, a technique for evaluating fuel consumption in the engine when the engine powers the hydraulic pump in a digging operation performed by a hy...
متن کاملReview of modelling and remote control for excavators
An excavator is a typical hydraulic heavy-duty human-operated machine used in general versatile construction operations, such as digging, ground levelling, carrying loads, dumping loads, and straight traction. However, there are many tasks, such as hazard environment (nuclear decomposition, earthquake, etc) which is not suitable human working on site. The remotely controllable excavators are re...
