Problems solved by technology

The problem often caused by this design is that the sensitivity of the joints is not as high as the direct drive, and at the same time, each joint is not completely independent, and there is a coupling phenomenon, that is, when a joint moves, other joints coupled with it will have linkage
If each joint uses an independent electromagnetic motor, it will result in a large and redundant structure

Abstract

The invention discloses a multi-degree-of-freedom palm based on a rod type ultrasonic motor and an operation method thereof. The multi-degree-of-freedom palm based on the rod type ultrasonic motor comprises a palm, a 10 mm ultrasonic motor, a forefinger near finger end, a forefinger middle finger end, a forefinger far finger end, a middle finger near finger end, a middle finger middle finger end,a middle finger far finger end, a ring finger near finger end, a ring finger middle finger end, a ring finger far finger end, a little finger far finger end, a little finger middle finger end, a little finger near finger end, a thumb far finger end, a thumb middle finger end, a thumb near finger end and a spherical hinge. The invention further provides an operation method of the multi-degree-of-freedom palm based on the rod type ultrasonic motor. The multi-degree-of-freedom palm is reasonably arranged at each joint part of a bionic manipulator by using the miniaturization characteristic of therod type ultrasonic motor, so that independence of each joint is guaranteed, and common functions of the bionic manipulator can be realized.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a multi-degree-of-freedom palm based on a rod-type ultrasonic motor and an operation method thereof. Background technique [0002] At present, the design of bionic manipulator mostly adopts the form of electromagnetic motor combined with rope drive and spring drive as finger joints. The problem often caused by this design is that the sensitivity of the joints is not as high as that of the direct drive, and at the same time, each joint is not completely independent, and there is a coupling phenomenon, that is, when a joint moves, other joints coupled with it will have linkage. If each joint adopts an independent electromagnetic motor, it will result in a large redundant structure. Contents of the invention [0003] The object of the present invention is to provide a multi-degree-of-freedom palm based on a rod-type ultrasonic motor and its operating method. This product takes a...
