In short: The "muscles and bones" of humanoid robots are getting their own factories outside China. Thailand's BOI approved combined initial investment of more than 10 billion baht.

Who is building what

Company Investment Product Province
Hangzhou Seenpin 2.12B baht Planetary roller screws, ball screws Chonburi
Beite Technology 1.67B baht (+ >3B under review) Planetary roller screws Chonburi
Sanhua Intelligent Drives 1.8B baht Actuators Chonburi
Tuopu Technology 930M baht Actuators Chachoengsao
Xusheng Group 2.7B baht Lightweight body, joint and structural parts Rayong

The BOI says the primary market includes global players such as Tesla's Optimus humanoid, and expects more than 1,000 high-skill jobs.

Why it matters

Planetary roller screws and actuators are among the most expensive parts of a humanoid. Building them in Thailand gives humanoid makers a second supply base and helps Chinese suppliers serve customers that want production outside China.
