In highly informative, perception-rich environments that we call Omniscient Spaces, robots interact with physical objects which in turn afford robots the information showing how the objects should be manipulated. Object manipulation is commonly believed one of the most basic tasks in robot applications. However, no approaches including visual servoing seem satisfactory in unstructured environments such as our everyday life. Thus, in Omniscient Spaces, the features of the environments embed themselves in every entity, allowing robots to easily identify and manipulate unknown objects. To achieve this end, we propose a new paradigm of the interaction through Radio Frequency Identification (RFID). The aim of this paper is to learn about RFID and investigate how it works in object manipulation. Specifically, as an innovative trial for autonomous, real-time manipulation, a likely mobile robot equipped with an RFID system is developed. Details on the experiments are described together with some preliminary results.

This paper propose G-code and G-Pedigree system that are development based on the e-Pedigree and EPC, and RFID solutions for logistics management is proposed. The proposed G-Pedigree system to include the forward logistics and reverse logistics all logistics and management systems are appropriate for the event, with security features, security and accessibility of critical data was strengthened. The proposed G-code systems and the EPC code of the existing RFID readers, tags can be applied to, the more you can manage the logistics-related information.

RFID/USN means a way of attaching RFID to all required objects to identify them and exchanging the required information through the network. High frequency (13.56MHz) has been commonly used in the field of processing management in Korea, and extremely short wave (433.92MHz) has been used for harbor logistics management by being attached to containers in the US. As for SCM field where we need to have a broader understanding, the research on $860{\sim}960MHz$, a sort of extremely short wave has been most actively conducted. Therefore, in-this study, in order to understand the features of all frequencies ranging and to design and implementation of RFID Middle System suitable for realizing u-Logistics by using those diverse frequencies.

One of RFID features is that each RFID tag has a unique identifying code. Logistic System utilizes RFID tag as location tracing, understanding stock or etc. On the other hand, there is a problem of overall lower recognition rate by getting the information of non-mobility tags with no need for reading. To solve this problem, we trace and analyze variation of moving and moveless RFID tag sensitivity by the hour. In analyzed data, we verify that tag sensitivity of mobile RFID is gradually increase while non-mobility tag has same intensity value. In order to detect mobile tag, we generate a function using Matlab with analyzed data and separate moving tags from non-mobility tags by software. As a result, we can confirm that non-mobility tags are detected by software and recognition rate of RFID tag is improved by separating moveless tag.

Agricultural products are one of the major food, But in recent years, It's not easy for Consumers to buy them. Cause there are not sure about the quality of the cheap foreign agricultural product imported. There are not even sure where they have been produced, Some excessive use of domestic pesticides, And Environmental pollution caused by soil contamination of plantation, It's not only matter with the conscience of the Sellers and producers. The government recommends agricultural producers to attach the mark to identify where the products are made originally. However, if producers do not comply with the recommendation, it become useless. Recently, because of the increased interest to health and food, Consumers want accurate and reliable information about The agricultural products, They buy. In this paper, Based on the RFID technology, RFID tags attached to agricultural products when consumers buy, Through the RFID reader to read RFID tags, Which make Easy to accurately convey Production of agricultural information and safety information to consumers. These features have been implemented with the traceability system.

This paper presents an advanced RFID reader system implementing multi-protocols and multi-standards at 900MHz. In accordance with the strict regulations specified by ISO 18000-6 B-Type and EPC Global Gen 2, we have designed corresponding systemic factors which meet the domestic radio frequency utilizing bands of 910-914MHz. In addition, we develop numerous crucial factors of system compatibility options including SSB (Single-Side Band) and DSB (Double-Side Band) specifications, also OOK (On-Off Keying), ASK (Amplitude Shift Keying) and PR-ASK (Phase Reversed-Amplitude Shift Keying) modulation formula. Remarkable technical features of system in this paper can be the direct conversion routines using I/Q Modulation/Demodulation respectively, and Full-Duplex formulation operating at identical frequency bands.

In this paper, we presented an active RFID system in 2.45GHz range including LNA, Mixer and gain block. And in this work, a link budget model for RFID applications are proposed. We describe the detailed design and implementation of our system. Our components in RFID system has features such as low Noise Figure, reliable energy budget, and standard compliance with ISO 18000-4. Our receiver is effective for development and evaluation of prototype applications because of the flexibility of the design hardware. So, our platform will be suitable for versatile item management applications.

RFID (radio frequency identification) systems, recently being used in a wide range of areas, are vulnerable to relay attack from malicious attackers. For that reason, Brands, et al. proposed a certification protocol between a certifier and a verifier based on the concept of distance-bounding, and in addition Hancke et al. introduced the concept of RFID. However, the delivery of tag IDs, one of the main RFID features, is not still available, and there are two important demerits: anonymity in the delivery of tag IDs suggested by Kim et al. and inefficiency in finding a tag ID with regard to how to check errors which may occur in the process of data exchange between readers and tags. Therefore, this study proposes a protocol that meets the requirements of tag anonymity and location untraceability, has resistance to errors which may take place in the phase of tag data exchange, and is very efficient in finding tag IDs.
