Actuate Robotics Conference Highlights Physical AI Surge and Hardware Bottlenecks

The Actuate robotics conference in Silicon Valley highlighted a massive surge in "Physical AI" funding, reaching $18.8 billion in 2026, alongside severe bottlenecks in hardware supply and real-world training data. Notably, Chinese hardware manufacturers like Unitree dominated the spotlight due to the lack of viable domestic hardware alternatives in the US. As AI transitions from digital software to physical environments, the robotics industry faces critical supply chain risks, particularly due to US FCC restrictions on foreign-made advanced robotics. Since Chinese manufacturers currently dominate humanoid robot shipments, these regulatory hurdles could significantly slow down Western robotics startups. The conference featured more data collection and labeling firms (such as Uber AI Solutions and Instawork) than hardware exhibitors, reflecting the scarcity of real-world training data. Additionally, industry leaders warned that US startups remain heavily dependent on Chinese hardware, which accounted for approximately 90% of global humanoid robot shipments last year.
