Adaptive robotic system for selective opening of flexible containers in waste streams

Abstract

A system for selectively opening flexible containers, such as plastic bags, in a mixed solid waste stream is disclosed, for use in Material Recovery Facilities (MRFs) or other contexts. The system may include a conveyor configured to transport waste, a sensor configured to detect the presence and position of flexible containers, and a multi-degree-of-freedom positioning device that moves a cutting tool relative to the containers. A processor, in communication with the sensor and positioning device, may calculate a cutting path and control the positioning device to execute the cutting operation. The system may utilize various cutting tools, including punches, blades, spades, shovels, and motorized saws, as well as non-contact fluid-based cutting technologies such as air or water jets. Additionally, the system can dynamically adjust the cutting trajectory based on real-time feedback and environmental conditions. The method provides an adaptable solution to open bags without damaging recyclable materials, improving throughput and reducing waste in mixed waste streams.
