Innovative projects

Startup with IBM

Our company has successfully integrated into the Startup with IBM program. Thanks to this, we have now become part of the IBM Global Entrepreneur Program, which provides us access to the latest IBM technologies such as Cloud, Data Science, IoT, Blockchain, and Artificial Intelligence.

Startup Smart@MAintenance

We are developing an innovative product called Smart@MAintenance, which focuses on the analysis and design of the system maintenance of electrical equipment. The basic idea of ​​this project comes from rich experience in the field of maintenance analysis.

Our startup project Smart@MAintenance was successfully defended in June 2019 and awarded by the expert committee in the Competition of Innovative Ideas and Startups – “Máš nápad? Prezentuj svoj startup!” (= “Do you have an idea? Present your startup!” ) This competition was announced by the Rector of the Technical University of Košice and organized by the University Science Park TECHNICOM in cooperation with the Slovak Business Agency and Saab AB.

 

Autonomous Inspection Robot

Our project introduces an innovative approach to the inspection and maintenance of electrical substations within the power grid. By leveraging an autonomous mobile robot equipped with an advanced sensor system and a modular extension, we enhance efficiency, safety, and precision beyond current industry standards. This solution minimizes human intervention in hazardous environments, reduces operational costs, and ensures more reliable performance of critical infrastructure.
