Revolution in space robotics: modular construction kit for flexible robots!

Researchers at the University of Bremen in collaboration with the German Research Center for Artificial Intelligence (DFKI) have developed an innovative modular system for space robotics. This system, called MODKOM (“Modular Components as Building Blocks for Application-Specific Configurable Space Robots”), aims to revolutionize the currently prevailing approach of specialized and mission-specific robots. Current robots are often tailored to a single mission, which means that new requirements require a lot of development effort. The modular approach makes it possible to flexibly adapt robots and react quickly to changing mission requirements. The project is funded by the DLR Space Agency and the Federal Ministry for Economic Affairs and Energy (BMWE) with around 3.2 million euros.

The innovative modular system combines hardware and software components that make it possible to configure mobile robots according to the “plug and play” principle. The basic elements include joints, structural elements and electronic components that are connected to each other through standardized interfaces. This modularity not only increases the flexibility but also the reliability of the robots, as defective units can be quickly replaced.

Flexibility and efficiency through modularity

The modular architecture of the system enables dynamic integration of the various components. The subsystems can be integrated as functional units with higher granularity. Complete systems are created from the combination of platforms, sensors, payload containers and manipulators. This significantly reduces development and qualification cycles and promotes a resource-saving approach to the design of new robots.

A central element of the project is a complex manipulation system that serves as a demonstration of the developed system. This system combines a modular manipulator with the HUNTER SE mobile platform and the iSSI® interface. In addition, the DFKI-X2D joint was developed as a highly dynamic motor specifically for use in space, with Technology Readiness Level (TRL) 5 having already been achieved through extensive qualification tests.

Outlook and future developments

An ISO-compliant clean room was set up at the DFKI in Bremen to enable the integration and testing of the modular elements. The knowledge and technologies collected will be incorporated into future space missions and will help optimize the construction and maintenance of space stations in orbit. These advances in space robotics have been further accelerated in recent years through high-tech production techniques and the integration of artificial intelligence.

The research landscape in the field of space robotics is dynamic and promising. Future developments could produce robots capable of independently performing complex operations such as repairs and building structures in space. These advances are being fueled by increasing interest and financial support from both governments and private sector entities. However, challenges such as long-term operations under changing gravity conditions and ethical questions when dealing with autonomous robots continue to be the focus of research.

In summary, it can be said that the modular system developed by the University of Bremen and the DFKI not only increases flexibility and efficiency in space robotics, but also paves the way for new technologies and applications. Making full use of these advances could significantly advance space research University of Bremen reports, Vogel reports, Robot favorable reported.
