Wind Power

Green capital goods have long been part of our portfolio—such as winding systems for wind power technology.

Hydrogen

Storing renewable energy is key to the energy transition. We deliver suitable plant concepts for this purpose.

PV Industry

Our 2D line tracking and 3D vision systems (including bin picking applications) provide reliable part detection, identification, and sorting for various component types.

Energy Storage

Whether it’s a stand-alone unit or a full production line—Rotte develops special-purpose machinery for your flexible production needs. Inventive engineering in service of our customers is our strength.

Automation Solutions for the Wind Power Industry

Wind energy is a key pillar of the energy transition—on land and at sea. With our customized special solutions, we support manufacturers of wind turbine components throughout the entire production chain. A particular focus is placed on our winding systems for rotor blade structures, which can be tailored to different geometries, materials, and component sizes.

With a high degree of automation, cycle times are reduced, scrap is minimized, and quality is standardized—all while maintaining maximum flexibility for different rotor blade designs.

Our systems handle tasks such as:

Precise winding of fiber composite materials (e.g., GFRP or CFRP)
Automated application of adhesives and sealants
Handling of large-volume components with synchronized motion control
Positioning and joining of complex geometries with real-time monitoring

Our System handle a wide range of tasks such as:

Automated processing of bipolar plates, electrodes, and membranes
Assembly of cell stacks with integrated sealing technology
Processing of hydrogen-carrying components in inert or cleanroom environments
Bonding and welding of sensitive assemblies with precise temperature and pressure control
Robotic quality control using industrial image processing and sensor-based inspection

Tailor-Made Machines and Systems for the Hydrogen Industry

The hydrogen economy demands high standards in automation technology—especially with regard to safety, process accuracy, and material handling. Our custom solutions for hydrogen-related production, storage, and processing offer future-ready systems for a growing technology market.

Our systems are used in the manufacturing of fuel cells, electrolyzers, and storage technologies.

Thanks to our expertise in robotics, conveyor systems, and machine vision, we provide fully integrated solutions that enhance operational efficiency across intralogistics, production, and process engineering. Our systems are scalable, modular, and easy to integrate into existing production environments. At the same time, our know-how enables you to build entire production lines as fully integrated system solutions.

Individual solutions for the solar industry

The production of PV modules is characterized by high volumes, sensitive materials, and a need for consistently high quality. We offer fully automated systems for manufacturing solar cells and PV modules—from cell singulation and stringing to lamination and final packaging.

Where photovoltaic systems are driving greener mobility, supplying clean electricity to homes and businesses, and already accounting for nearly 20% of Germany’s electricity generation, Rotte’s custom production systems are enabling an even faster shift to a sustainable future. Our systems are tailored precisely to your product geometries and production capacities—with the goal of ensuring highly efficient, scalable, and future-proof manufacturing.

Our customers benefit from a wide range of capabilities:

Complete solutions for line automation
High-precision handling of fragile substrates
Integrated image processing for quality control
Smart robotic cells for assembly, sorting, and palletizing
Modular systems for flexible plant expansion

Our capabilities in this field include:

Systems for cell and module production (e.g., for lithium-ion or solid-state batteries)
Assembly and inspection cells with integrated image processing
Fully automated testing and sorting systems for energy storage components
Custom production line layouts for small and large-scale manufacturing

Innovative solutions for energy storage

Storing renewable energy is essential to the success of the energy transition. Rotte develops automated manufacturing systems for battery storage technologies and other storage solutions designed to meet the highest demands for safety and performance.

The systems we develop can be flexibly adapted to various cell formats (e.g., pouch, cylindrical, or prismatic cells) and provide maximum process reliability with excellent scalability. Your ideas and goals are our highest priority at every stage of the project. The market demands increasingly more from available energy solutions. You should expect more from us.
