Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] A biped robot gait generation and optimization method figure 1 Shown:

[0035] Such as figure 2 As shown, the biped robot can be divided into six states according to the different supporting legs during the walking process, which are the initial state of the robot standing on the ground with both feet, the state of only the right foot supporting 1, and the state of the left foot touching the ground. 2. The state of the left foot support 3, the state of the right foot touching the ground 4 and the state of flying, set the joint target angle and walking reference speed through the state inf...

Abstract

The invention discloses a gait generation and optimization method for a biped robot. The method is characterized in that a gait library of the biped robot is constructed in a finite state machine according to a target pose of the state of the biped robot; mutual switching conditions among all states of the robot are set and triggered; in each state switching process, a joint cubic interpolation method is used for planning the movement track of support legs, and a gauss pseudo-spectral method is used for optimizing the movement track of swing legs; and finally, the gait of the biped robot in different motion modes is generated by the finite state machine. According to the gait generation and optimization method for the biped robot, the constraint of ZMP is not considered, and all the bipedrobots with or without the sole edges of the feet can generate the walking track by the method; and the planning process is simple and operable and is more suitable for online generation, and the biped walking robot can stably walk and finish walking, running, jumping and other actions by matching with a simple control strategy.

Description

technical field [0001] The invention belongs to the technical field of humanoid robots, and in particular relates to a method for generating and optimizing the gait of a biped robot. Background technique [0002] The biped robot has the characteristics of human appearance, uses bipedal walking, two-handed operation, is easy to adapt to the human working environment and uses human tools, etc., so that it has important applications in the aging society family service, public safety and other dangerous environment operations, national defense and other fields need. Although biped robots have made remarkable achievements in motion planning, balance control, operation and system integration in a structured environment, compared with the wide application of industrial robots in industrial production, biped robots are far from practical applications. big gap. The walking gait of a biped robot directly affects the walking performance of the robot. Different gaits have different ch...
