Tele-operated excavation system using installation-type robot manipulator with motion feedback sensor

Abstract

Excavation and earthmoving equipment mostly operate in accident-prone areas. These areas normally have rollover, confinement, and fall or may be considered harmful work areas due to demolitions and sewage removals. It is inevitable that excavation and earthmoving systems should be developed to secure the safety of operators through unmanned and remote control systems. Therefore, this research proposes a system that enables excavators to be unmanned and remote-controlled without any renovation, remodeling by applying attachable and separable mechanism and modules. Moreover, this research proposes the sensor concept to evaluate the dynamic status without processing remodeling or transformation the existing hydraulic drive excavation system by adopting the easy attachable and separable mechanism. The study verifies this proposal based on observed possibility and feasibility through the experiments. © 2014 TSI Press.
