Simulation of Tele-Operated Electro-Hydraulic Actuator and Excavator's Boom

This paper, we present our study called TeleOperated Hydraulic Actuator which implying the usage of remote-controlled hydraulic system to control a mini excavator from a distance. Mini excavator comprises several motion mechanisms such as of swing, boom, arm and bucket. Simulation on the tele-operated electro-hydraulic actuator on boom mechanism has been conducted. The entire hydraulic system is modeled and simulate by using MATLAB software. The simulation result is discussed and described in order to analyze several system characteristics, given a certain working condition, within the simulation perio

Earthmoving construction automation with military applications: Past, present and future

© ISARC 2018 - 35th International Symposium on Automation and Robotics in Construction and International AEC/FM Hackathon: The Future of Building Things. All rights reserved. Amongst increasing innovations in frontier engineering sciences, the advancements in Robotic and Autonomous Systems (RAS) has brought about a new horizon in construction applications. There is evidence of the increasing interest in RAS technologies in the civil construction sector being reflected in construction efforts of many military forces. In particular, Army or ground-based forces are frequently called upon to conduct construction tasks as part of military operations, tasks which could be partially or fully aided by the employment of RAS technologies. Along with recent advances in the Internet of Things (IoT) and cyber-physical system infrastructure, it is essential to examine the current maturity, technical feasibility, and affordability, as well as the challenges and future directions of the adoption and application of RAS to military construction. This paper presents a comprehensive survey and provides a contemporary and industry-independent overview on the state-of-the-art of earthmoving construction automation used in defence, spanning current world’s best practice through to that which is predicted over the coming years
