Heitec presents a new generation of mobile robotics for the cleanroom. What makes HUGS stand out?

'HUGS' (Heitec Universal.GMP.Solution) is a modular, autonomous robot system that has been specially developed for use in GMP-regulated cleanrooms and is offered by Heitec as a complete solution including documentation, integration and service. It combines a mobile platform, such as the Stäubli Sterimove, with interchangeable top modules for tasks such as tube handling, microbiological sampling or automated disinfection. All components are designed to be validatable, cleanable and compliant with Annex 1 of the EU GMP guidelines. The system documents all process steps digitally and can be seamlessly integrated into higher-level IT structures such as MES. HUGS thus offers a flexible, secure and scalable solution for automating manual activities in sensitive production areas. The first application shows automated environmental monitoring with four monitoring samples. HUGS performs these automatically, thus relieving the workload on cleanroom personnel.

What were the particular challenges in developing a mobile robotics solution for GMP-regulated environments?

The biggest challenge was to combine the high dynamics of a mobile system with the strict requirements for hygienic design and validation. Any movement can change air flows or mobilize particles, which is critical in aseptic areas. In addition, the system had to be designed to be resistant to chemicals, cleanable and validatable for disinfection processes. Another key component was complete documentation in accordance with DQ, IQ, OQ and PQ to ensure GMP conformity.

To what extent does HUGS support the vision of a scalable smart factory?

HUGS is designed as an open, modular system and can be seamlessly integrated into existing production and IT infrastructures via standardized interfaces. By combining a mobile platform and interchangeable modules, the same system can take on a wide range of tasks - from material transportation and measuring tasks to disinfection. All movements, process parameters and environmental data are recorded digitally and can be used for analyses or audit trails. Several robots can be coordinated in a fleet management system and dynamically integrated into production processes. This makes Heitec HUGS a scalable building block on the way to a data-driven, validatable smart factory.

Have you already planned further developments or additional modules?

Yes, we are currently working on the integration of camera systems, as well as UV-C/H₂O₂ disinfection modules and transport solutions in cleanrooms up to GMP class A. At the same time, software enhancements for fleet management, route optimization and predictive maintenance are being developed. We are also in talks with customers to implement their specific requirements for mobile robotics in cleanrooms.

How do you rate the acceptance of mobile robots in cleanrooms at pharmaceutical or biotechnology companies?

In our view, interest in mobile, autonomous robotics in cleanrooms has increased significantly in recent years - also driven by the new Annex 1 'automate to minimize the risk of contamination' and the desire for stable, validatable processes. Critical issues primarily concern the validation effort and cleanroom suitability. However, initial pilot projects show that contamination risks can be significantly reduced and cleaning times considerably shortened. The documented, reproducible process sequence, which facilitates audits and increases operational safety, is particularly impressive.
