Paper folding structure capable of conducting self-folding based on light drive

Abstract

The invention discloses a paper folding structure capable of conducting self-folding based on light drive. The paper folding structure is formed by arranging and combining a plurality of rectangular units. Each rectangular unit is of a sheet structure with the front face and the back face, and each rectangular unit is in left-right symmetry with the center line as the boundary. The front face andthe back face of each rectangular unit are provided with light sensing pasters, the corresponding front light sensing pasters are fixed to the corresponding left diagonal line and the corresponding right diagonal line which are crossed, and the back light sensing pasters are fixed to the center lines and the boundary of every two adjacent rectangular units. The light sensing pasters are bent towards the side deviating from the rectangular units under irradiation, the whole structure is driven to be bent towards the back faces along the center lines and the boundary of every two adjacent rectangular units, and meanwhile, the whole structure is bent towards the front faces along the diagonal lines on the left side and the right side. According to the paper folding structure, light drive is integrally adopted, the response speed is high, a triangular plane unit not deforming and the connecting line of two adjacent plane units serve as a rotation pair, and the folding and unfolding processof the structure is accurately controlled.

Description

Technical field [0001] The invention belongs to the technical field of flexible robots, and particularly relates to an origami structure based on light-driven self-folding. Background technique [0002] Flexible robotics technology has made rapid progress in the past decade. Researchers around the world have experimented with different materials and designs to allow rigid robots to bend and interact with humans in a more natural way. However, enhancing the flexibility of the robot often means a compromise in strength, because softer materials are generally not as strong as rigid materials, which also limits the use of flexible robots. [0003] Inspired by the high-strength origami structure, various self-folding structures and devices have been designed in combination with modern applications, including remote control robots, microfluidic chemical analysis, tissue engineering, artificial muscles, etc. It also has a variety of applications in real life and scientific research, suc...
