Abstract

The invention discloses a three-degree-of-freedom biomimetic jumping mechanical leg, belonging to the field of biomimetic robots. The leg includes feet soles, mechanical calves, mechanical thighs anda body, further includes a composite ankle joint, a composite knee joint and a composite hip joint; each joint comprises a joint body, a joint power unit and a joint energy storage mechanism, and theankle power unit is the same as the knee power unit and the hip power unit, and each device includes a two-way memory material and a heating element; an ankle joint energy storage mechanism, the kneejoint energy storage mechanism, the hip joint energy storage mechanism have the same structure and comprise elastic storage elements, thermally bonded coatings A installed on the boss A and thermallybonded coatings B installed on the boss B, wherein the boss A and the boss B are composed of piezoelectric materials, and resistance wires for heating are arranged inside the thermally bonded coatingA and the thermally bonded coating B. The invention relates to a biomimetic jumping mechanical leg with simple structure and three degrees of freedom, which drives joint motion by relying on memory material.

Description

technical field [0001] The invention mainly relates to the field of bionic robots, in particular to a three-degree-of-freedom bionic jumping mechanical leg. Background technique [0002] With the continuous development of robot technology, the application of robots will require it to have strong energy to overcome obstacles to adapt to the complex landform environment in nature. In the prior art, the jumping of the bionic jumping robot is mainly realized by regressive bounce, which is mainly completed by a hydraulic drive or a spring, resulting in a large volume, complex structure and control, and a large self-weight, which makes the robot consume more energy when jumping . Contents of the invention [0003] The technical problem to be solved by the present invention is: aiming at the technical problems existing in the prior art, the present invention provides a three-degree-of-freedom bionic jumping mechanical leg with a simple structure, which relies on memory materials...
