RFID Localisation For Internet Of Things Smart Homes: A Survey
The Internet of Things (IoT) enables numerous business opportunities in
fields as diverse as e-health, smart cities, smart homes, among many others.
The IoT incorporates multiple long-range, short-range, and personal area
wireless networks and technologies into the designs of IoT applications.
Localisation in indoor positioning systems plays an important role in the IoT.
Location Based IoT applications range from tracking objects and people in
real-time, assets management, agriculture, assisted monitoring technologies for
healthcare, and smart homes, to name a few. Radio Frequency based systems for
indoor positioning such as Radio Frequency Identification (RFID) is a key
enabler technology for the IoT due to its costeffective, high readability
rates, automatic identification and, importantly, its energy efficiency
characteristic. This paper reviews the state-of-the-art RFID technologies in
IoT Smart Homes applications. It presents several comparable studies of RFID
based projects in smart homes and discusses the applications, techniques,
algorithms, and challenges of adopting RFID technologies in IoT smart home
systems.Comment: 18 pages, 2 figures, 3 table

people and advances in technology which will make new uses possible and provides suggestions for some of these new
applications. The paper also considers the design and other conditions to be met for user acceptance. It also discusses
the complementarity of assistive service robots and personal assistance and considers the types of applications and
users for which service robots are and are not suitable
Robotic Wireless Sensor Networks
In this chapter, we present a literature survey of an emerging, cutting-edge,
and multi-disciplinary field of research at the intersection of Robotics and
Wireless Sensor Networks (WSN) which we refer to as Robotic Wireless Sensor
Networks (RWSN). We define a RWSN as an autonomous networked multi-robot system
that aims to achieve certain sensing goals while meeting and maintaining
certain communication performance requirements, through cooperative control,
learning and adaptation. While both of the component areas, i.e., Robotics and
WSN, are very well-known and well-explored, there exist a whole set of new
opportunities and research directions at the intersection of these two fields
which are relatively or even completely unexplored. One such example would be
the use of a set of robotic routers to set up a temporary communication path
between a sender and a receiver that uses the controlled mobility to the
advantage of packet routing. We find that there exist only a limited number of
articles to be directly categorized as RWSN related works whereas there exist a
range of articles in the robotics and the WSN literature that are also relevant
to this new field of research. To connect the dots, we first identify the core
problems and research trends related to RWSN such as connectivity,
localization, routing, and robust flow of information. Next, we classify the
existing research on RWSN as well as the relevant state-of-the-arts from
robotics and WSN community according to the problems and trends identified in
the first step. Lastly, we analyze what is missing in the existing literature,
and identify topics that require more research attention in the future
Mobile Robot Self Localization based on Multi-Antenna-RFID Reader and IC Tag Textile
This paper presents a self-localization system
using multiple RFID reader antennas and High-Frequency
RFID-tag textile floor for an indoor autonomous mobile robot.
Conventional self-localization systems often use vision sensors
and/or laser range finders and an environment model. It is
difficult to estimate the exact global location if the environment
has number of places that have similar shape boundaries or
small number of landmarks to localize. It tends to take a long
time to recover the self-localization estimation if it goes wrong at
once. Vision sensors work hard in dark lighting condition. Laser
range finder often fails to detect distance to a transparent wall.
In addition, the self-localization becomes unstable if obstacles
occlude landmarks that are important to estimate position of
the robot. Door opening and closing condition affects the self-
localization performance.
Self-localization system based on reading RFID-tags on floor
is robust against lighting condition, obstacles, furniture and
doors conditions in the environment. Even if the arrangement
of the obstacles or furniture in the environment is changed,
it is not necessary to update the map for the self-localization.
It can localize itself immediately and is free from well-known
kidnapped robot problem because the RFID-tags give global po-
sition information. Conventional self-localization systems based
on reading RFID-tags on floor often use only one RFID reader
antenna and have difficulty of orientation estimation. We have
developed a self-localization system using multiple RFID reader
antennas and High-Frequency RFID-tag textile floor for an
indoor autonomous mobile robot. Experimental results show
the validity of the proposed methods.2013 IEEE Workshop on Advanced Robotics and its Social Impacts (ARSO)

Alpha-N: Shortest Path Finder Automated Delivery Robot with Obstacle Detection and Avoiding System
Alpha N A self-powered, wheel driven Automated Delivery Robot is presented in
this paper. The ADR is capable of navigating autonomously by detecting and
avoiding objects or obstacles in its path. It uses a vector map of the path and
calculates the shortest path by Grid Count Method of Dijkstra Algorithm.
Landmark determination with Radio Frequency Identification tags are placed in
the path for identification and verification of source and destination, and
also for the recalibration of the current position. On the other hand, an
Object Detection Module is built by Faster RCNN with VGGNet16 architecture for
supporting path planning by detecting and recognizing obstacles. The Path
Planning System is combined with the output of the GCM, the RFID Reading System
and also by the binary results of ODM. This PPS requires a minimum speed of 200
RPM and 75 seconds duration for the robot to successfully relocate its position
by reading an RFID tag. In the result analysis phase, the ODM exhibits an
accuracy of 83.75 percent, RRS shows 92.3 percent accuracy and the PPS
maintains an accuracy of 85.3 percent. Stacking all these 3 modules, the ADR is
built, tested and validated which shows significant improvement in terms of
performance and usability comparing with other service robots.Comment: 12 pages, 7 figures, To be appear in the proceedings of 12th Asian

Path planning for automatic recharging system for steep-slope vineyard robots
Develop cost-effective ground robots for crop monitoring in steep slope vineyards is a complex challenge. The terrain presents harsh conditions for mobile robots and most of the time there is no one available to give support to the robots. So, a fully autonomous steep-slope robot requires a robust automatic recharging system. This work proposes a multilevel system that monitors a vineyard robot autonomy, to plan off-line the trajectory to the nearest recharging point and dock the robot on that recharging point considering visual tags. The proposed system called VineRecharge was developed to be deployed into a cost-effective robot with low computational power. Besides, this paper benchmarks several visual tags and detectors and integrates the best one into the VineRecharge system.This work is financed by the ERDF – European Regional Development Fund through the Operational Programme for Competitiveness and Internationalisation - COMPETE 2020 Programme within project “POCI-01-0145-FEDER-006961”, and by National Funds through the FCT – Fundação para a Ciência e a Tecnologia (Portuguese Foundation for Science and Technology) as part of project UID/EEA/50014/2013.info:eu-repo/semantics/publishedVersio
