Title:
SOFT MUSCLE, TRANSMISSION STRUCTURE, ROBOT, MANUFACTURING METHOD FOR SOFT MUSCLE, AND DESIGN METHOD FOR MECHANICAL ARM
Document Type and Number:
WIPO Patent Application WO/2024/078577
Kind Code:
A1
Abstract:
Provided in the present disclosure are a soft muscle, a transmission structure, a robot, a manufacturing method for the soft muscle, and a design method for a mechanical arm. The soft muscle comprises two end surfaces, a flexible side wall and a driving source interface. The flexible side wall and the end surfaces enclose a chamber. The flexible side wall comprises a multi-layer stacked structure having uniformly-distributed strain. The stacked structure having uniformly-distributed strain is provided with folding surfaces. Crease surfaces are formed at joint portions of the folding surfaces of adjacent layers. Combination of the shape, the thickness and the stacking mode of strain units enables strain to be uniformly distributed on the folding surfaces rather than concentrating at crease portions, and, during the compression or extension process of the stacked structure having uniformly-distributed strain, the invasion angle θ changes between 0° and the maximum invasion angle θmax, and the creases only move along the axis along with the crease surfaces and do not deform. The internal stress of the stacked structure having uniformly-distributed strain itself is very small, thereby endowing the soft muscle with high energy conversion efficiency and long service life.
