Robot simulated jump aid

Abstract

The invention relates to a robot simulated jump aid. Both ends of a rocker rod are respectively hinged with a connecting rod and a support seat, a leg connecting rod is respectively hinged with the support seat and the connecting rod for forming a parallelogrammic connecting rod mechanism, the ratio of the long edge to the short edge of the connecting rod mechanism is 4 / 3, one side of the support seat is provided with a sole connecting rod parallel to the support seat, an electromagnet control mechanism is fixed at a hinging part of the rocker rod and the support seat, a toe plate is hinged with one end of the sole connecting rod through a toe joint rotating shaft, a torsional spring is sheathed and arranged on the toe joint rotating shaft, a connecting body is fixed at the shaft end of a telescopic shaft of an electromagnet, and one surface of the connecting body is matched with the outer arc surface of a baffle block. In the jumping process of the invention, the support seat, the sole connecting rod and the toe plate sequentially leave the ground, the acting time of the foot and the ground is prolonged, the ground leaving speed of the mass center is accelerated, and the jump acid function is realized. The landing process is opposite to the jumping process. The jumping performance of a jumping robot fixedly connected with the device can be improved through simulating the functions of the hamstring tendon and the feet in the animal jumping process.

Description

technical field [0001] The invention relates to the field of robots, in particular to a bionic jump-assisting device for a robot. Background technique [0002] Robots that move by jumping can cross obstacles that are several times or even tens of times their own size, and are especially suitable for complex environments with obstacles such as terrain survey, rescue, and anti-terrorism, and have become a research hotspot in the field of robotics. [0003] The earliest jumping robot used an inverted pendulum as a principle model to realize a simple bouncing function, such as the continuous jumping robot in a single-degree-of-freedom plane of MIT. Later, people got inspiration from bionics, and developed jumping robots with bionic functions according to the movement mechanism and structural characteristics of animals, such as the frog-like intermittent jumping robot jointly developed by NASA and the California Institute of Technology, which realized the jumping process. The bi...
