Fabric Handling with Passive Actuator Less Grippers

Conference invited talk at 2025 WRC Symposium on Advanced Robotics and Automation (WRC SARA), Beijing, China


Paper Abstract
The automation of fabric destacking and pick-and-place operations is critical for garment manufacturing. Conventional grasping solutions, such as pinching, suction, electro-adhesive, or needle-based grippers, are fundamentally limited by their reliance on active actuation and external power sources. We propose the Passive Actuator-Less Gripper (PALGRIP), a novel, fully mechanical end-effector for fabric manipulation. PALGRIP utilizes an internal mechanism that converts from the relative movement between the housing of the gripper and the fingers to open-and-close motion of the fingers, enabling it to grasp a topmost single fabric from a fabric stack without requiring any onboard power or tethered supplies. By its passive, power-free design, PALGRIP facilitates low-cost, simplified system integration, presenting a significant advancement in accessible automation for the textile industry. In this talk, the concept and mechanical design of PALGRIP and its application will be presented.
