Transforming Remanufacturing Automation with Large Language Models: A Forward-Looking Analysis with Case Studies
Chang Liu, Sara Behdad, Prabhakar Pagilla +2
With growing concerns about resource scarcity and environmental degradation, remanufacturing of end-of-life (EoL) products within the circular economy is attracting increasing atte…
Learning When to See and When to Feel: Adaptive Vision-Torque Fusion for Contact-Aware Manipulation
Jiuzhou Lei, Chang Liu, Yu She +2
Vision-based policies have achieved a good performance in robotic manipulation due to the accessibility and richness of visual observations. However, purely visual sensing becomes…
Evaluating Large and Lightweight Vision Models for Irregular Component Segmentation in E-Waste Disassembly
Xinyao Zhang, Chang Liu, Xiao Liang +2
Precise segmentation of irregular and densely arranged components is essential for robotic disassembly and material recovery in electronic waste (e-waste) recycling. This study eva…
SELF-VLA: A Skill Enhanced Agentic Vision-Language-Action Framework for Contact-Rich Disassembly
Chang Liu, Sibo Tian, Xiao Liang +1
Disassembly automation has long been pursued to address the growing demand for efficient and proper recovery of valuable components from the end-of-life (EoL) electronic products.…
Vision-Language-Action Models for Selective Robotic Disassembly: A Case Study on Critical Component Extraction from Desktops
Chang Liu, Sibo Tian, Sara Behdad +2
Automating disassembly of critical components from end-of-life (EoL) desktops, such as high-value items like RAM modules and CPUs, as well as sensitive parts like hard disk drives,…
RAISE: A Robot-Assisted Selective Disassembly and Sorting System for End-of-Life Phones
Chang Liu, Badrinath Balasubramaniam, Neal Yancey +6
End-of-Life (EoL) phones significantly exacerbate global e-waste challenges due to their high production volumes and short lifecycles. Disassembly is among the most critical proces…
