Unsafe hoisting behaviors are the fuse of tower crane overturning safety accident. However,
the hoisting operation has a certain degree of randomness and invisibility, and it is …

An adaptive motion/force controller is developed for unilateral or bilateral teleoperation
systems. The method can be applied in both position and rate control modes, with arbitrary …

Earth-moving machines such as hydraulic excavators are usually used for carrying out
contact tasks. Impedance control can be employed as an approach for achieving compliant …

A novel yet simple approach for experimental determination of the link (mass and inertia-
related) parameters and friction coefficients is developed for a typical excavator arm. The …

This paper investigates the performance demands of a haptic interface and shows how this
information can be used to design a suitable mechanism. A design procedure, previously …

A four-channel control architecture has been suggested in the literature to achieve
transparency for master-slave teleoperator systems under position control. In this paper, the …

This paper presents differential equations of motion of a hydraulic excavator in the form of
Kane's equations. The equations proposed allow studying the excavator dynamics in the …

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 …

On the basis of an open source engine Delta3D, a PC-based excavator simulator has been
developed in this paper for training human operators and evaluating control strategies for …

This paper presents the results of an on-going project and investigates modelling and
remote control issues of an industry excavator. The details of modelling, communication, and …
