Mecka AI, a startup that collects and analyzes human motion data to train humanoid and other robots, has raised $60 million in Series B funding led by Sequoia Capital, with participation from Nvidia, Microsoft's venture fund M12 and Qualcomm, among others. CEO and cofounder Josh Gao said scaling physical AI will require major investment in sensors, infrastructure and real-world data collection, including capturing force and pressure from physical interactions. TechCrunch previously reported the round valued the company at close to $500 million.
