RoboCT Brings Large-Scale Computed Tomography Out of the Lab
Comprehensive computed tomography (CT) inspection of large industrial components has traditionally been limited to specialized laboratory environments equipped with high-precision mechanical systems and significant infrastructure. That limitation is changing with RoboCT, a robot-assisted computed tomography solution that enables high-resolution 3D CT scanning of large and complex components directly in industrial environments.
Originally developed to support demanding inspection applications in the aerospace sector, RoboCT is now gaining traction in automotive manufacturing, where it enables engineers to analyze complete vehicles and large assemblies during early development without the need for destructive disassembly. The technology provides manufacturers with a powerful new approach to identifying hidden defects, validating assemblies, and accelerating product development. X-RAYLAB developed RoboCT in collaboration with the Fraunhofer EZRT X-ray Center.
Robot-Based CT for Large Components
Unlike conventional CT systems that rely on highly accurate mechanical positioning stages, RoboCT uses industrial robots to position both the X-ray source and detector around the inspection object. This robot-assisted approach removes many of the size constraints associated with traditional CT systems while significantly increasing flexibility.
The challenge of using industrial robots for precision metrology lies in their positioning accuracy, which is substantially lower than dedicated laboratory CT equipment. RoboCT overcomes this through patented software algorithms that compensate for robot positioning errors during image acquisition and reconstruction.
Rather than relying on expensive ultra-precise mechanical systems, the software performs intelligent geometric calibration and correction, enabling the accurate reconstruction of high-quality CT volumes—even for demanding micro-computed tomography applications where fine detail is essential.
The result is a system capable of producing reliable 3D CT data from components that were previously impractical or impossible to inspect using conventional laboratory equipment.
Complete Turnkey Inspection Platform
RoboCT is supplied as a complete turnkey solution combining both hardware and software.
The standard configuration includes:
- A RoboCT basic system comprising a tube robot system, detector robot system, and X-ray booth
- Integrated software for system control and image acquisition
- Geometric calibration software
- 3D CT reconstruction software
- Visualization tools for both 2D radiography and full 3D CT analysis
The modular architecture also allows the system to be configured for specific inspection requirements. Optional additions include a rotary table for rapid circular CT scans, as well as additional robots carrying extra detectors or X-ray sources, including microfocus systems for higher-resolution imaging.
Scalable for Everything from Automotive to Aerospace
One of RoboCT’s defining characteristics is its scalability. The minimum system footprint measures approximately 5 × 6 × 3 metres, supporting inspection of objects with cross-sections up to 5 × 3 × 3 metres. For larger applications, the system can be scaled up to 30 × 10 × 5 metres, allowing inspection of components up to 30 metres long and 6 metres wide.
This scalability opens opportunities for non-destructive testing of complete vehicles, aircraft structures, industrial energy storage systems, and other oversized assemblies that have traditionally fallen outside the practical limits of conventional CT technology.
Replacing Mechanical Precision with Software Intelligence
A significant innovation behind RoboCT is its shift away from costly precision mechanics.
Traditional laboratory CT systems depend on highly accurate positioning axes to achieve measurement precision. RoboCT instead transfers much of this precision requirement into software, using intelligent calibration and reconstruction algorithms to compensate for the inherent inaccuracies of industrial robots.
This software-driven approach reduces the reliance on expensive mechanical engineering while maintaining the image quality required for demanding industrial inspection applications. The result is a more flexible and cost-effective CT platform that can be deployed for significantly larger inspection tasks.
Simplifying Industrial CT Deployment
Beyond supplying the hardware and software, RoboCT is delivered as a complete turnkey package that includes installation, commissioning, and operator training. This enables manufacturers to integrate advanced CT inspection into production and development environments with minimal implementation effort.
As manufacturers increasingly seek earlier insight into product quality and hidden internal defects, robot-assisted CT offers an attractive alternative to conventional laboratory-based inspection. By combining industrial robotics with advanced computational reconstruction, RoboCT extends the reach of computed tomography beyond traditional size limitations, enabling comprehensive non-destructive inspection of some of the industry’s largest and most complex components.
For aerospace, automotive, energy, and heavy industrial manufacturers, this represents a significant step toward more accessible, scalable, and flexible 3D CT inspection.
