At the Weibo live streaming event initiated by Sina Technology themed "When will humanoid robots enter homes?", regarding the technical bottlenecks of humanoid robots, Sun Jiao, a partner at Siasun Robot&Automation Capital, believes that in terms of Hardware, based on actual commercial application, humanoid robots have many high-precision movements that still need breakthroughs; in terms of models, large language models have developed well with abundant underlying data, but the small brain models and action models are limited by previously scarce data and are still in progress and iteration, so these two areas remain significant bottlenecks.
