Design principles for manipulation with astrictive contact
Abstract/Contents
- Abstract
- Anthropomorphic hands have existed in research circles for over thirty years, yet simple, parallel grippers continue to be the norm in manufacturing and real-world applications because they deliver strong grips in a light and compact package. Many-jointed hands have significant kinematic advantages over their less mobile counterparts but must also deliver robust strength without sacrificing that dexterity if they are to be adopted in more practical settings. Astrictive contact conditions, achieved through suction, gecko-inspired adhesives, and micro-spines, can improve grasp quality without decreasing mobility or increasing actuation effort but demand a novel set of design considerations. Rather than normal forces and point contacts, the principles of high contact area, shear load sharing, and even normal stress distribution determine the limits of manipulation capacity. These three conditions are explored theoretically and implemented practically on four robotic manipulators. Together, these prototypes form a framework for manipulation with astrictive contact through a combination of passive mechanical structures, practical controls, and novel actuation schemes.
