flag UBTech's stock soars 150% in 2025 as it targets 500 humanoid robots by year-end, but real-world autonomy remains unproven.

flag UBTech's stock has surged over 150% in 2025 as the company aims to deliver 500 humanoid robots by year-end, but real-world evidence of autonomous factory performance remains limited. flag Despite promotional demonstrations, most humanoid robots—including those from Tesla and other firms—operate in controlled settings, are tethered, or require remote control. flag Experts like Toby Walsh of the University of NSW argue that bipedal designs are inefficient for industrial tasks, with wheeled and arm-based robots already outperforming them in manufacturing and logistics. flag The focus on human-like forms, Walsh says, is driven more by investor appeal and science fiction appeal than practicality, diverting attention from more effective specialized robotics.
