Symmetrical centrifugal force power single-leg jumping machine

Abstract

The invention provides a symmetrical centrifugal force power single-leg jumping machine, comprising a motor module for supplying power, a mass block group, a supporting plate and a spring leg sleeve for storing energy, wherein the supporting plate is an axisymmetric body; the mass block group comprises even number of mass blocks and the mass blocks are axially symmetrically distributed by taking the supporting plate as a symmetry axis; the mass block group and the motor module are connected through a transmission shaft; the motor module drives the mass blocks at the two sides of the symmetry axis of the supporting plate to rotate in an opposite direction; a component force of a generated centrifugal force in the vertical direction is overlapped and a component force of the centrifugal force in the horizontal direction is offset; and the motor module is fixedly arranged at one side of the supporting plate and the spring leg sleeve is fixedly arranged at the other side of the supporting plate. The symmetrical centrifugal force power single-leg jumping machine disclosed by the invention has the characteristics of stability in jumping, simplicity in controlling and the like.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a single-leg jumping machine powered by symmetrical centrifugal force. At the same time, the invention can be applied to the field of fitness equipment, especially the automatic jumping bar. Background technique [0002] In the field of jumping robots, the United States has relatively mature research in this field. The Raibert team at the Massachusetts Institute of Technology conducted in-depth research on jumping robots before researching Big Dog military robots. The single-leg multi-dimensional stable continuous jumping robot designed and invented by the team also represents the highest level in the field of jumping robots. However, domestic research in this field is not particularly sufficient at present.

Problems solved by technology

[0003] The technical problem to be solved by the present invention: the continuous and stable jump of the one-legged jumping robot will continuously lose energy, so a suitable power input device is needed to provide power. According to its jumping characteristics, the power input should be in the vertical direction of its jumping and It does not affect the balance of the robot itself when jumping; the jumping of the robot needs to be coherent, and each take-off requires the instantaneous release of sufficient energy, and it cannot cause too much impact on the mechanical structure. It is difficult to realize the instantaneous release of energy and the avoidance of impact at the same time. When the mechanical structure is complex, it will increase the difficulty of control and adjustment to achieve continuous jumping
