In this study we focus on adding wireless intelligence to machines and systems to be used in production applications. The key enabling technologies of piloted mechatronic systems were RFID (Radio-Frequency Identification) and WSAN (Wireless Sensor and Actuator Network). This work is mainly done in a project “Ubiquitous Computing in Maintenance Using Sensors and RFID Tags”. There were several industrial partners in the project. The main goal is to develop solutions that are suitable for industry. Several systems piloted in harsh industrial environments are considered in the paper.
