Title:
SMART SOFT ACTUATION UNIT FOR UNDERWATER APPLICATIONS
Document Type and Number:
WIPO Patent Application WO/2021/218487
Kind Code:
A1
Abstract:
Disclosed are soft origami actuators with embedded optical waveguides and underwater manipulator applications.An underwater manipulator with a gripper is also presented, actuated with the same soft origami actuators. The main contributions of this disclosure include: 1) coupling of stretching and bending are eliminated by combing origami soft actuators and special designed optical waveguide; 2) the optical waveguide is designed such that no cladding is needed which largely reduces fabrication complexity; and 3) a new hybrid underwater manipulator is described, with redundant position feedback for accuracy and dexterous underwater applications.
