Hydraulic driving system for bionic joints and air pipes of robot

Abstract

The invention discloses a hydraulic driving system for bionic joints and air pipes of a robot, which comprises a high-pressure chamber, a low-pressure chamber, a booster pump, three groups of three-phase four-way valves, an MCU (Microprogrammed Control Unit) capable of controlling the three groups of three-phase four-way valves and a power supply, the liquid outlet end of the booster pump communicates with one end of a first one-way conduction high-pressure pipe, the liquid inlet end of the booster pump communicates with a pipeline, one end of the pipeline communicates with the low-pressure chamber, one side of the high-pressure chamber communicates with a second one-way conduction high-pressure pipe, and the two ends of the high-pressure chamber communicate with second-stage high-pressure chambers through first high-pressure pipelines correspondingly. According to the bionic robot, high-pressure liquid is mostly adopted for driving the movable joints, so that the bionic robot is flexible in movement, large in load, capable of being highly integrated, low in noise and higher in simulation degree, and almost can simulate movement of most joints and air pipes of animals.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a hydraulic drive system of a robot bionic joint and a trachea. Background technique [0002] A robot is a kind of intelligent machine that can work semi-autonomously or fully autonomously. Robots have basic characteristics such as perception, decision-making, and execution. They can assist or even replace humans in completing dangerous, heavy and complex work, improve work efficiency and quality, and serve human life. To expand or extend the range of human activities and abilities, with the continuous development of technology, bionic robots are gradually being perfected. [0003] However, most of the driving systems of the traditional robot bionic joints are driven by a large number of metal components and overweight motors, resulting in a very slow response of the robot, a lot of noise during operation, and high power consumption, which makes the bionic robot unable to Integra...

Problems solved by technology

[0004] The purpose of the present invention is to provide a hydraulic drive system for robot bionic joints and trachea, to solve the problem that the drive systems of traditional robot bionic joints proposed in the above background technology are mostly driven by a large number of metal devices and overweight motors, thus causing the robot to react It is very slow, and there is a lot of noise during operation, and at the same time, it consumes a lot of power, which makes it impossible for bionic robots to be integrated, and the problem of high maintenance costs
