Advancements in computing technologies and automation have achieved remarkable growth in the last few decades. These advancements improve not only very common areas of our daily life but also areas of education, health, production industries, etc. Internet of Things (IoT), Robotics, and Automation are the recent advancements in technology gaining huge research attention due to the requirement of different types of integration and automation. The objective of IoT is to connect the wide range of devices and services that share data and information with each other.On the other hand, the main aim of Robotics is to design and develop an intelligent machine that works like a human. However, the objective of Automation is automatic control of different systems for operating various machines to reduce human efforts and time to increase accuracy. Now a days, each and every person is connected with Internet by using different types of communication devices. IoT covers various scenarios such as smart grid, smart city, environment monitoring, and healthcare monitoring systems, etc. According to a prediction done by CompTIA, the number of devices connected to the internet will reach up to 50 billion by 2021. Robotics also play an important role in reducing the human effort and implementing the concept of smart grid, smart city, etc. Therefore, IoT, Robotics, and Automation are interrelated to each other to reduce human efforts. Lots of research work have been done in each domain but various problems are still available to improve the quality of services in every domain.The objective of this conference is to present a collection of articles that cover recent research results and comprehensive reviews in the field of IoT, Robotics, and Automation. In particular, this Fourth International Conference on “Innovation in IoT, Robotics and Automation (IIRA 4.0)” will be a platform to bring together professionals, academic researchers and scientists interested in techniques inspired by engineering, technological and scientific advancement in the field of IoT, Robotics and Automation.
