Problems solved by technology

However, these studies are mainly used to achieve simple flat ground walking, lack of adaptive analysis in complex unstructured environments, and most of the research is on multi-legged robots or passive biped walking robots, and there are very few studies on active robots.

Abstract

The invention provides a humanoid robot gait generation method. The method comprises the following steps: S1, establishing an initial walking pattern generator by analyzing the driving characteristic of human walking, and generating a joint driving torque up used for realizing basic walking movement; S2, establishing a mathematical model of a stretch reflex and a mathematical model of a vestibular reflex through the partial characteristic of a sensory reflex, overlaying a joint driving torque ustretch generated by the stretch reflex and a joint driving torque uvest generated by the vestibular reflex to the joint driving torque up, and adjusting the joint trajectory of a robot in the movement space by adjusting the joint driving torques ustretch and uvest, so as to ensure that a supporting leg of the robot does not leave the ground and a swinging leg of the robot can reach a right position in the walking process; S3, establishing a ZMP (Zero Moment Point) reflex model, overlaying a joint driving torque uzmp generated by a ZMP reflex to the joint driving torques ustretch, uvest and up, further adjusting the joint trajectory by adjusting the joint driving torque uzmp. Thus, the robot can realize stable walking movement, and the adaptive capacity to environment of movement of the robot is improved.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a method for generating gaits of a humanoid robot. Background technique [0002] Gait planning, that is, gait generation algorithm, refers to generating joint trajectories that satisfy specified gait parameters. The gait planning of humanoid robot must not only satisfy the geometric configuration and kinematics characteristics, but also must maintain the stability of walking. On the other hand, the flexibility of walking movement and environmental adaptability must also be considered. So far, there are two main types of gait planning for humanoid robots. One is the model-based method, which is currently the main method used for gait planning of humanoid robots. The other is the non-model-based method, which mainly utilizes the biological characteristics of human walking and combines certain correction algorithms or control strategies to obtain an effective gait. [0003] The mod...
