Automatically telescopic robot leg

Abstract

The invention discloses an automatically telescopic robot leg. The robot leg consists of a motion unit, an upper / low fixing seat, an upper / low electromagnet, a sleeve, a U-shaped block, a spring plate and a spring, wherein the upper electromagnet and the lower electromagnet have fixed and opposite polarities; the polarity of the moving electromagnet is variable; and when the robot leg moves, the moving electromagnet and the upper / low electromagnet form variable attraction (repulsion) or repulsion (attraction), so that the motion unit is driven to move up and down, and the telescopic function of the robot leg is realized. Compared with the prior art, the automatically telescopic robot leg has the advantages that automatic telescopic function of the robot leg can be realized, and the robot leg is convenient to control and high in motion precision; and the robot leg is high in response speed, safe, reliable, simple and compact in structure, convenient to process and mount and particularly suitable for a robot without the knee joint.

Description

technical field [0001] The invention relates to the field of robots, in particular to an automatically retractable robot leg. Background technique [0002] Robots can replace humans in many tasks in handling, welding and daily life, especially some repetitive and boring tasks, so they have become a research hotspot in recent decades. In the application process of robots, good stability and high efficiency are required. Designing robots that meet the above two requirements has become the research focus and difficulty of scholars and researchers. [0003] A humanoid robot can imitate the walking gait of a human being, and in the process of walking, the robot can move forward by using the flexion and extension of the hip joint and knee joint. For example, the Chinese patent document CN101121424A discloses a multi-degree-of-freedom biped robot lower limb mechanism, which can realize the humanoid gait walking of the biped robot to the greatest extent, is economically feasible, a...

AI Technical Summary

Problems solved by technology

When the robot leg moves through flexion and extension, it generally needs multiple motors to drive each joint, which will involve the determination of the initial state and the coordination of variables, which increases the complexity of the control system.

In addition, most of the current humanoid robot legs have insufficient motion precision, slow response, reliability and stability still need to be improved, and the structure is relatively complex.
