A legged robot is provided whose trunk link is not prone to wobble in the front-back direction during walking. The legged robot is equipped with a trunk link and a pair of legs. Each leg has a pitch joint capable of rotating the connected links in a plane that intersects with a line extending in a lateral direction of the robot. Rotation centers of the pitch joints are located above a center of gravity of the trunk link. The legged robot walks mainly by swinging the legs backward and forward around such rotation centers. Hence, the trunk link wobbles mainly in the front-back direction around the rotation centers as the robot walks. Because the center of gravity of the trunk link is located below the rotation centers, the gravitational force acting on the trunk link acts in a direction to suppress swinging of the trunk link during walking. Due to this, the trunk link of the legged robot is not prone to wobble in the front-back direction during walking.

The invention relates to a multi-wavelet fusion feature based neuron action feature extraction method. The method comprises the following steps of: denoising an original action potential signal by using fast wavelet transformation to acquire a denoising action potential signal; performing multi-wavelet base analysis on the denoising signal to acquire a plurality of groups of wavelet time frequency features; respectively fusing the wavelet features with different sizes to acquire a multi-wavelet feature of action potential; and respectively fusing a low-frequency component and a high-frequency component of the signal through the multi-wavelet fusion feature according to features of different wavelet bases to acquire a group of new time frequency features. By adopting the method, mutation and phase step features of the signal are kept, so that the high-frequency component and the low-frequency component of the signal are restored to a certain extent; meanwhile, information and position of a phase step or mutation point of the signal are kept unchanged.
