This work is about the 3D animation of artificial intelligence learning walking ability. According to Darwin's theory of evolution, early humans evolved to walk upright. The same newborn baby learns to roll over and crawl to walk upright through constant imitation attempts. Today's artificial intelligence can also train walking ability through reinforcement learning algorithms, learn walking animation through repeated trial and error, and learn to walk upright after thousands of iterations. This work is a visual representation of the learning process of artificial intelligence upright walking, by showing the training process and visual effects of artificial intelligence upright walking animation, causing the audience to think about the future of artificial intelligence. The continuous development of this way of using artificial intelligence technology to make character animation will also change the thinking mode and process steps of animators in making character animation in the future. The relationship between human work positions and artificial intelligence tools also needs further thinking and planning.
