Therefore, adjust trim to the highest level, then start AC1, wait for the right leg to be lifted completely, and then start AC2. After seeing that the left leg is lifted, this indicates that the walking machine is completed. (Finally, after turning on AC1 and AC2, please do not turn off, or you will be at your own risk.) AC3 starts the waist rotation system, which is controlled by the vertical take-off and landing slider, and AC4 starts the leg fine-tuning system, which is controlled by the vertical take-off and landing slider. This product can climb some gentle slopes, it is recommended that you do not climb more than 20 °
