This book is about the topic of Mobile Cloud Robotics. Cloud Robotics emerged in 2010. This leverages the fusion of multiple technologies, such as the Internet of Things, mobile robotic platforms, Multicore Graphics Processing Units, and the Cloud platform. The Cloud concept involves virtualizing the compute element, as we'll explain in detail later. Mostly, we will focus on mobile robots, as opposed to robotic assembly, and warehousing. At the heart of the problem is a computation-communication-power usage trade-off. We will look at the integration of these topics, with a roadmap and a defined architecture.
