Liquid metal pressure-driven type robot joint and self-generating electricity device

Abstract

The invention discloses a liquid metal pressure-driven type robot joint and self-generating electricity device. The liquid metal pressure-driven type robot joint and self-generating electricity devicecomprise a thermal-temperature-difference electricity generation liquid metal pressure working cylinder, a liquid metal magnetofluid generator, a servo valve, a magnetic pump, a robot joint body, a sensor, an intelligent controller, a one-way valve, a filter, an overflow valve and a liquid metal storage tank, a super capacitor. The liquid metal pressure working cylinder and a thermal-temperature-difference generator are combined to form an integrated structure, and the thermal-temperature-difference electricity generation effect is produced. The thermal-temperature-difference electricity generation liquid metal pressure working cylinder and the liquid metal magnetofluid generator are combined, and liquid metal of the robot joint device passes through a magnet and cuts a magnetic force line to produce liquid metal magnetofluid electricity generation effect. Therefore, the robot joint device has the dual self-generating electricity functions of thermal temperature difference electricitygeneration and magnetofluid electricity generation, and provides the electric energy guarantee for the walking motion of a robot.

Description

technical field [0001] The invention relates to the field of robots, and relates to a liquid metal pressure-driven robot and self-generating application technology, more specifically, to a liquid metal pressure-driven robot joint and a self-generating device. Background technique [0002] With the continuous development of science and technology, people need to seek a human substitute to complete some dangerous work tasks in harsh environments. In recent years, the rapid development of robotics has brought expectations. Robots can ideally adapt to the living environment and tools used by humans, and can carry out human-machine dialogue and communication.

Problems solved by technology

However, the electric drive method has its weaknesses, such as being unable to bear large loads and often requiring external connections with large and cumbersome transmission devices; the motor is also prone to damage due to high operating temperature due to excessive loads, etc.

With the increase of the load, the output power of the motor needs to be increased in the electric drive mode, which will cause the increase of the volume and weight of the motor, so it has a great impact on the overall robot system. Similarly, if the power of the motor is not increased, the transmission device needs to be increased. This not only reduces the speed but also increases the weight of the robot system
