Humanoid Robots: Is Full-Stack, All-Scenario Coverage a Moat or a Burden?

Unitree Robotics secured its ticket for a STAR Market IPO with a valuation of 42 billion yuan and annual revenue of 600 million yuan. Meanwhile, UBTECH's stock price has continued to slide, proving that companion robots haven't become the savior they were hoped to be. Behind these two sets of data lies a clash between two completely different technical paths and business logics. As someone who has long observed AI implementation, what I see isn't "who wins or loses," but rather how cost structures and delivery efficiency are redefining competitive moats as the entire industry transitions from the technology validation phase to commercialization.
