Recently, a large-scale EPCglobal network rapidly increasing, the vision of a large-scale EPCglobal network is close to becoming a reality. However, there is neither a research for efficient accessing EPCIS(EPC Information Service) repository and distributing to the business application. In this paper, we propose a real-time architecture of effective accessing EPCIS repository based on RFID push services...
Quad-robot type (QRT) unmanned aerial vehicles (UAVs) have been developed for quick detection and observation of the circumstances under calamity environment such as indoor fire spots. The UAV is equipped with four propellers driven by each electricmotor, an embedded controller, an Inertial Navigation System (INS) using three rate gyros and accelerometers, a CCD (Charge Coupled Device) camera with...
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...
As the conditions of working environment at the construction site cannot be typified, intelligence of robot system is considered to be the best solution for a lack of uniformity and homogeneity such as various kinds of unexpected situations or conditions. Precise finishing quality of robot system, pre-fabrication system of construction materials, and undisturbed material circulation system also remains...
This research was conducted to develop the system for an installation-type remote control operation for the existing excavator without renovation. It was also conducted to supplement the shortcomings of the existing remote control operation, and to develop a system for applying the multi-yoke-type transmission mechanism and the slide roller mechanism. In addition, this study seeks to develop a system...
Owing to the increasing number of high-rise buildings and large glass facades and the resulting problem of safe and effective maintenance, many trials have taken place in the last few years to develop automated cleaning systems. So as to guide the robot's movement on the facade, this study proposes the built-in-guide type building maintenance robot system using additional module such as guidance mullion...
This study is about developing an exoskeleton Continuous Passive Motion (CPM) with the same Range of Motion (ROM) and instant center of rotation as the human knee. The key feature in constructing a CPM is an accurate alignment with the human knee joint enabling it to deliver the same movements as the actual body on the CPM. In this research, we proposed an exoskeleton knee joint through kinematic...
