Four-foot walking robot through rigidly transmitting driving power by internal-combustion engine

Abstract

The invention relates to a four-foot walking robot platform, a high-efficiency walking mode which combines the power technology of the existing automobiles, tanks and tractors and the modern computer and robot technology is found under the existing research result of a multi-foot robot, so as to build a combined driving mode, an internal-combustion engine is used for providing driving force rigidly through a cam, and a servo hydraulic pressure driver is used for providing steering force and regulating balance posture; 99 percent of the driving force is provided by the internal-combustion engine rigidly when the robot walks straightly on the flat road, when the robot walks on the uneven road or turns, a hydraulic pressure driving system is used for carrying out the tasks of regulating the balance posture and steering, therefore, the power of the hydraulic pressure driving system can be reduced, the using frequency of the hydraulic pressure driving system is reduced, the service life is prolonged, the robot can imitate the four-foot animal completely, the continuous, smooth, stable, strong and high-efficiency walking is realized, and long-time contiguous working can be carried out under complex environment.

Description

technical field [0001] The invention relates to a robot structure, specifically a multi-legged robot structure. Background technique [0002] The mobile modes of robots or vehicles mainly include wheeled, crawler, striding and hybrid. Among them, the wheeled and crawler-type mobile modes are restricted by the environment, and the working range is relatively small. Pedestrian robots or vehicles that walk on strides can replace wheeled and tracked robots or vehicles to complete tasks in complex environments, and can also save energy; there is an increasing need for multi-legged walking vehicles or robots to meet people's special needs and improve transportation tools. The ability to pass through rough roads or roadless conditions, or engage in some work that the human body cannot do by itself, from the ancient "wooden cow and horse" to the modern American Boston Dynamics developed a four-legged walking called "big dog". The robot, which is designed for the U.S. military, is ...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the multi-legged walking vehicles or robots are driven by multiple electric motors or hydraulically driven, and completely rely on the robots driven by multiple electric motors. The weight is heavy, and its kinetic energy is converted from electric energy. Can not work continuously for a long time in the actual operation process, completely rely on the same low hydraulic drive energy utilization rate, self-heavy; existing multi-legged walking vehicles with striding travel have the following common shortcomings: (1), transmission efficiency in the actual operation process (2) Insufficient power during actual operation; (3) Cannot fully imitate quadrupeds in nature to achieve coherent, smooth and smooth walking

(4) Energy supply is inconvenient, and it cannot work continuously for a long time during actual operation
