Core Viewpoint - The article discusses the innovative manufacturing method for soft robots based on programmable fabric stacking, which overcomes traditional manufacturing limitations and enables the creation of multifunctional soft robots [2][5][7]. Group 1: Manufacturing Challenges and Innovations - Current mainstream methods for soft robot manufacturing face significant challenges, including reliance on manual operations and limited functionality [1]. - The proposed method by the research team from Peking University utilizes programmable fabric stacking, allowing for the creation of multifunctional soft robots with reduced manual assembly [2][4]. - The new method combines laser cutting and 3D printing technologies to enhance precision and consistency in the manufacturing process [4][12]. Group 2: Technical Details of the New Method - The core of the new manufacturing method involves programming the contour and bonding paths of each fabric layer, enabling the overall manufacturing of the robot [7][8]. - The team uses thermoplastic polyurethane (TPU) coated nylon fabric as the sole material, ensuring strong inter-layer bonding through thermal processes [8][9]. - The manufacturing process includes precise laser cutting of fabric layers and sequential stacking, resulting in an integrated robot structure without the need for manual assembly [9][12]. Group 3: Multifunctional Soft Robots Developed - The research team successfully developed three multifunctional soft robots: a large-range soft manipulator, an amphibious robot, and a cable-free soft robotic fish, showcasing significant performance and functional integration advantages [13][14]. - The large-range soft manipulator can extend from an initial height of 8 mm to 243 mm, achieving a stretch ratio of 2941% and featuring a three-finger gripper with a maximum bending angle of 110.3° [14][16]. - The amphibious robot can adapt its body shape for various locomotion modes, including crawling, walking, jumping, and swimming, demonstrating strong adaptability to complex environments [17][18]. - The cable-free soft robotic fish integrates swimming and grasping functions, achieving a maximum swimming speed of 1.04 BL/s and a maximum grasping force of 21.4 N [19][21].
