Benefits of technology

This patented technology allows for flexibility in controllably changing its properties based upon real world requirements without adding too much weight or complexity compared to current designs. It offers various benefits like adaptability to varying environmental conditions (such as bending) while maintaining stability when used indoors. Additionally, this design makes robots more efficient than traditional legs due to their lack of rigid components. Overall, these technical improvements improve performance over conventional systems.

Problems solved by technology

Technology Problem addressed in this patented text relates to improving the performance (energy efficiency) and environmental adaptation capabilities of walking robins due to their unique features like being able to move smoothly along uneven surfaces without getting stuck while maintaining stability. These challenges include reducing energy usage, making them difficult to operate safely at all types of terrains where there may be noisy obstacles present, preventing damage if they happen unexpectedly, enabling fast response times, allowing usherence between physical movements and movement patterns, providing flexibility and adjustability over various terrains, creating a safe and comfortable body motion pattern, and achieving higher levels of humility than current models.

Abstract

The invention discloses an elastic assembly capable of providing non-linear variable rigidity. The elastic assembly comprises a casing, a clamping assembly and a clamped piece, wherein the clamping assembly and the clamped piece are connected with the casing and are used for providing variable clamping forces, the interior of the clamping assembly is provided with an elastic piece which is used for providing all or part of clamping forces, the clamped piece is provided with a clamped surface for changing the clamped thickness of the clamped piece, and the clamped piece is used for outputting non-linearly-variable rigidity/force under the action of the variable clamping force provided by the clamping assembly. The elastic assembly has the advantages that the structure is compact, the running is reliable, and the elastic assembly can be applied to occasions requiring the non-linear rigidity; on one hand, the fixed non-linear rigidity is provided, and on the other hand, the rigidity is actively adjusted; the method is convenient for arranging robot joints, by utilizing the elasticity and variable rigidity, the safety problem of the robot in contact with people or unknown environments is favorably solved, and the variable rigidity property of human or animal limbs is favorably simulated, so the moving robot is more approximate to the variable rigidity property of the human or animals, the kinetic energy efficiency of the robot is improved, and the dynamic high-speed movement is realized.
