Digital Fabrication of Soft Actuated Objects by Machine Knitting

摘要

With recent interest in shape-changing interfaces, material-driven design, wearable technologies, and soft robotics, digital fabrication of soft actuatable material is increasingly in demand. Much of this research focuses on elastomers or non-stretchy air bladders. Computationally-controlled machine knitting offers an alternative fabrication technology which can rapidly produce soft textile objects that have a very different character: breathable, lightweight, and pleasant to the touch. These machines are well established and optimized for the mass production of garments, but have received much less attention as general purpose fabrication device compared to other digital fabrication techniques such as CNC machining or 3D printing. In this work, we explore a series of design strategies for machine knitting actuated soft objects by integrating tendons with shaping and anisotropic texture design.
