A Leg Connection Structure for Biomimetic Insect Robots

Abstract

The invention discloses a leg connection structure for a bionic insect robot. The leg connection structure comprises a supporting plate, a long supporting rod, a first short supporting rod, a second short supporting rod, a moving rod, a driving mechanism and a T-shaped shaft. The long supporting rod and the short supporting rods are in inserting connection onto the supporting plate, the moving rod is in match connection with the T-shaped shaft, and the driving mechanism comprises a first shape memory alloy (SMA) spring, a second SMA spring, a third SMA spring and a fourth SMA spring. Two ends of each of the first SMA spring and the second SMA spring are connected with the moving rod and the long supporting rod through connection wires, the third SMA spring is connected with the first short supporting rod and the T-shaped shaft, and the fourth SMA spring is connected with the second short supporting rod and the T-shaped shaft. The leg connection structure for the bionic insect robot is simple in structure, stable in performance, low in manufacture cost, flexible in motion, low in driving voltage, free of pollution and noise, capable of improving adaptability of the robot to the environment and corresponding with bionic concepts.

Description

technical field [0001] The invention belongs to the technical field of bionics, and in particular relates to a leg connection structure for a bionic insect robot. Background technique [0002] Robot technology is an interdisciplinary subject, involving mechanics, mechanics, electronics, biology, computer, artificial intelligence, systems engineering and other disciplines. Bionic robots are a hot topic in robot research at home and abroad. In recent years, relevant research has made great progress For example, in the 2012 Spring Festival Gala, a lifelike robot dance was performed. Scientists and engineers from Japan, France and other countries even launched robots with certain intelligence. Chinese scholars have also carried out research on auxiliary robots, rescue robots, and bionic insects. However, most of these robot leg movements are driven by motors, and the structural design is relatively complex, bulky, high in production cost, difficult to control, and has a large ga...

Problems solved by technology

However, most of these robot leg movements are driven by motors, the structural design is relatively complex, bulky, high production cost, difficult to control, and there is a big gap with the human body and biology in terms of human-machine interface and flexibility.

[0003] With the development of technology, the movement modes of various mobile robots are also different. Among them, footed robots mainly rely on bionic limbs to move. The existing bionic limbs have complex structures, heavy weight, and cumbersome installation. In addition, relying on motors to drive bionic limb movements, there are still problems such as high noise and difficult control
