CircuBot – AI-Powered Modular Collaborative Robotic System for Object Sorting
SHORT SUMMARY
CircuBot is a modular collaborative robotics TestBed designed to support experimentation, validation, and deployment of advanced waste-sorting technologies. It integrates collaborative robots, AI-driven computer vision, soft adaptive gripping, and cloud-based data analytics to enable safe, flexible, and efficient separation of recyclable materials such as PET bottles, metal cans, and small electronic components.
The TestBed provides a controlled yet realistic industrial environment for testing circular economy solutions under real-world conditions, supporting Technology Readiness Levels (TRL) 3–8. CircuBot enables rapid Proof-of-Concept validation and performance assessment for DeepTech innovations in robotics and artificial intelligence.
Aligned with Industry 5.0 principles, CircuBot emphasizes human-centric automation, environmental sustainability, and resilient manufacturing by improving worker safety, enhancing material recovery, and enabling data-driven process optimization. Within the CITADELS framework, the TestBed offers accessible infrastructure for research organizations, SMEs, and industry stakeholders to develop and validate intelligent, sustainable automation solutions.

APPLICATION CASES
| Application case: | Short description: |
| Automated industrial sorting (robot control & manipulation) | Fully autonomous robotic sorting of waste on a conveyor belt. AI-based vision performs real-time object detection and classification, while motion planning generates efficient pick-and-place or pick-and-toss actions using a soft robotic gripper adaptable to irregular shapes. |
| Collaborative human–robot sorting (real-time object detection & task allocation) | Shared human–robot workspace enabling safe collaboration during sorting tasks. Real-time perception and safety monitoring support dynamic task allocation, with robots handling repetitive items and humans managing complex or uncertain objects. |
| Sorting strategy design and optimization | Experimental evaluation and optimization of sorting strategies, including conveyor speed, grasping methods, and robotic cell layouts, using performance metrics such as throughput, accuracy, purity rate, and cycle time. |
| AI model training, validation, and benchmarking | Training and benchmarking of machine-learning models for waste classification under realistic conditions, including variable lighting, occlusions, cluttered scenes, and mixed-material streams. |
| Education, research, and innovation support | Use of the CircuBot testbed for student projects, academic research, professional training, and proof-of-concept demonstrations for SMEs and startups, supporting technology transfer and skill development. |
