Replaceable Bit-based Gripper for Picking Cluttered Food Items
Prashant Kumar, Yukiyasu Domae, Weiwei Wan +1
The food packaging industry goes through changes in food items and their weights quite rapidly. These items range from easy-to-pick, single-piece food items to flexible, long and c…
Prompt2Craft: Generating Functional Craft Assemblies with LLMs
Vitor Hideyo Isume, Takuya Kiyokawa, Natsuki Yamanobe +3
Inspired by traditional handmade crafts, where a person improvises assemblies based on the available objects, we formally introduce the Craft Assembly Task. It is a robotic assembl…
Learning-based Cooperative Robotic Paper Wrapping: A Unified Control Policy with Residual Force Control
Rewida Ali, Cristian C. Beltran-Hernandez, Weiwei Wan +1
Human-robot cooperation is essential in environments such as warehouses and retail stores, where workers frequently handle deformable objects like paper, bags, and fabrics. Coordin…
Hierarchical Planning and Scheduling for Reconfigurable Multi-Robot Disassembly Systems under Structural Constraints
Takuya Kiyokawa, Tomoki Ishikura, Shingo Hamada +2
This study presents a system integration approach for planning schedules, sequences, tasks, and motions for reconfigurable robots to automatically disassemble constrained structure…
Soft Regrasping Tool Inspired by Jamming Gripper
Takuya Kiyokawa, Zhengtao Hu, Weiwei Wan +1
Regrasping on fixtures is a promising approach to reduce pose uncertainty in robotic assembly, but conventional rigid fixtures lack adaptability and require dedicated designs for e…
Shell-Type Soft Jig for Holding Objects during Disassembly
Takuya Kiyokawa, Ryunosuke Takebayashi, Kensuke Harada
This study addresses a flexible holding tool for robotic disassembly. We propose a shell-type soft jig that securely and universally holds objects, mitigating the risk of component…
