CoPoT investigated and prototypically implemented a system environment for connected power tools. The overall system consists of three levels: an intelligent power tool, a smart toolbox as an edge-computing unit, and a cloud platform. The cordless screwdriver is equipped with sensors, communication interfaces, and actuators to detect usage situations, provide measurement data, and automatically adapt operating parameters. The toolbox handles local data storage, preprocessing, and communication with other devices such as smartphones or tablets. The cloud platform provides central analysis of anonymized usage data, model and algorithm management, and the delivery of recommendations. The project developed hardware and electronics demonstrators, cloud and edge components, machine-learning algorithms, data models, interfaces, and a validation environment. User studies, living-lab scenarios, and demonstrators were used to assess practical applicability. Particular attention was paid to data protection, IT security, edge computing, adaptive data processing, and transferability to other power tools and IoT applications.
