Abstract

The invention aims to provide a mechanism for simulating the jumping of frog rear legs. The mechanism comprises a body mechanism, a thigh mechanism, a shank mechanism and a sole mechanism, wherein the body mechanism comprises a left side body supporting plate and a right side body supporting plate; the thigh mechanism comprises a left side thigh supporting plate, a right side thigh supporting plate and a thigh fixing plate; the shank mechanism comprises a shank rotating mechanism, a shank reset mechanism and a shank telescopic mechanism; the sole mechanism comprises two sole seats. According to the mechanism provided by the invention, a four-connecting rod mechanism is formed in a way that connecting rods are replaced by ropes, the design is carried out by utilizing a connecting rod principle, the simulation degree of the frog rear legs is increased, and high simulation performance is realized; the flexibility of legs is enhanced, and the effects of jumping and buffering are increased.

Description

technical field

[0001] The invention relates to a robot structure, specifically a jumping mechanism. Background technique

[0002] Nowadays, robots play more and more roles in people's lives. The research field of robots is expanding towards the direction of complex terrain, unstructured environment and task autonomy. Compared with wheeled or tracked robots, legged robots will receive more and more attention, and the research of jumping robots is more active. The jumping robot has outstanding obstacle-surmounting ability, and can even overcome obstacles several times its own size, and has a large range of motion. The explosiveness of jumping can also avoid damage to oneself. More importantly, the jumping movement mode has the characteristics of low energy consumption. These advantages make the bionic legged jumping robot suitable for applications such as archaeological exploration, interstellar exploration, and anti-terrorist rescue activities. However, some of the curr...
