USORA: Unified solution of remote access in practical vocational engineering education

This paper presents an innovative framework concept combined with online labs for teaching and learning of engineering subjects. The concept integrates comprehensive approaches of different classical and innovative aspects. The paper gives an overview of current state-of-art technologies in remote and virtual labs and some existing activities for transnational online experimentation frameworks. New comprehensive teaching and learning concept for robotics and smart devices is presented together with practical results. The implemented remote lab portal - DistanceLab is presented in detail focusing on three different remote labs: Virtual microcontroller lab, Smart greenhouse lab, and Mobile robot lab.
