Non-prehensile robotic sorting for flexible packaging

Overview

Non-prehensile robotic sorting offers a transformative approach to handling multi-layer flexible packaging in recycling facilities. Unlike traditional systems that rely on grasping or suction, this solution employs learned pushing actions to direct and segregate items in mixed waste streams. This method is particularly effective for flexible packaging, which often presents challenges due to its deformability and overlapping nature. The system not only enhances separation quality but also ensures high throughput, making it an ideal addition to existing sorting infrastructures.

Technical specifications

• Non-prehensile manipulation: Uses learned pushing actions for effective steering and separation.
• ActivePusher framework: Rapidly learns manipulation policies for unfamiliar objects using minimal interaction data.
• Object identification algorithms: Employs state-of-the-art technology for identifying novel objects via a ceiling-mounted camera.
• Modular design: Operates upstream, integrating seamlessly with current sorting processes to improve efficiency without necessitating major workflow changes.

Technology readiness level

Currently at Technology Readiness Level (TRL) 3, the solution is in the stage of active development and laboratory validation. Over the next 12 months, efforts will focus on advancing to TRL 4–5, with plans to adapt the framework to real-world materials and conditions, integrate perception capabilities, and demonstrate a lab-scale prototype compatible with existing setups.
