With the introduction of Apple’s App Store, and the Google Play store smartphone devices have been given features one would not think possible on a cell phone. One of the target categories for app developers is health, due to the sensors provided in current smartphones an application can be developed to track a user’s health. The apps currently on the market motivate users through mostly goal based challenges between themselves or their friends. HeartMate is an iOS mobile application that utilizes the sensors in the iPhone, and the use of a Bluetooth LE connected heart rate monitor to create a new competitive, motivational, real time social experience using heart rates as a performance measure.

Home Automation system using IoT is a system that uses laptops or smart phones to control the basic home functions and features using internet from anywhere around the world. It is used to save the electricity and human energy. Home automation is the automatic control and monitoring of household appliances and residential house features like TV, fans, lights, doors, gate and even the windows. Events can be programmed to be triggered under specific conditions (such as depending on the sensors data), and this can be used in reducing the total energy consumed by some appliances. On the other hand, the system can suggest smart task scheduling. In simple installations, domotics may be as straightforward as turning on the lights when a person enters the room. In advanced installations, rooms can sense not only the presence of a person inside but know who that person is and perhaps set appropriate lighting, temperature, taking into account the day of the week, the time of day, and other factors. Keywords: Internet of Things (IoT), Raspberry Pi, Arduino, Zigbee, Automation, Image Processing 1.

  • A Practical Approach of an Internet of Robotic Things Platform
    DEGREE PROJECT IN MECHANICAL ENGINEERING, SECOND CYCLE, 30 CREDITS STOCKHOLM, SWEDEN 2018 A Practical Approach of an Internet of Robotic Things Platform ROBERT YOUSIF KTH ROYAL INSTITUTE OF TECHNOLOGY SCHOOL OF INDUSTRIAL ENGINEERING AND MANAGEMENT Master of Science Thesis TRITA-ITM-EX 2018:737 A Practical Approach of an Internet of Robotic Things Platform Robert Yousif KTH Industrial Engineering and Management Approved Examiner Supervisor Martin Törngren Jinzhi Lu Commissioner Contact person ÅF Håkan Roos Abstract This thesis aims to design and develop a platform based on a novel concept - the Internet of Robotic Things (IoRT) constructed by a robotic platform, an Internet of Things (IoT) platform and cloud computing services. A robotic platform enables hardware abstraction, facilitating the management of input/output between software, mechanical devices and electronic systems. The IoT platform is a global network enabling a massive number of devices known as things to communicate with each other and transfer data over the Internet. Cloud computing is a shared pool of scalable hardware usually provisioned as cloud services by third party cloud vendors. The integration of these concepts constitutes the core of the IoRT platform, as a global infrastructure facilitating robots to interconnect over the Internet utilizing common communication technology. Moreover, the pool of cloud resources shared by the connected robots enables scalable storage and processing power. The IoRT platform developed in this study constitutes firstly of the Amazon Web Service (AWS) IoT core serving as the IoT platform. Secondly, it incorporates the Robot Operating system (ROS) as the robotic platform and thirdly the cloud services Amazon DynamoDB and AWS Lambda for data storing and data processing respectively.
