Its current flagship product is the industrial Walker S series, piloted in car factories for material handling and sorting; the Walker S2, released in July 2025, can swap its own battery using both arms, enabling continuous operation, and reports say it landed several orders worth over RMB 100 million each in 2025. On the model side, UBTech has built its own Thinker model stack in-house, open-sourcing the Thinker-4B vision-language model in early 2026.
