[0123] Embodiment 2

[0124] As Figure 9 In the embodiment, the body 11 has a connecting interface 15 outside, and the humanoid robot further comprises an expansion pack 4, which is detachably connected with the body 11 through the connecting interface 15.

[0125] In actual use, the expansion pack 4 can be an AI backpack.

[0126] The above only describes the preferred embodiments of the application, and does not limit the patent protection range of the application, and any equivalent structural transformation, direct or indirect application in other related technical fields, are all included in the protection range of the application.
