Industrial Strategy Analysis: Open-access research funded by DARPA & DoD grants laid the mathematical and mechanical foundations of proprioceptive legged locomotion. By leveraging Shenzhen's specialized high-pole winding factories and rapid die-cast tooling, commercial Chinese firms compressed 10-unit prototype costs ($45,000+) to sub-$2,000 consumer and industrial quadrupeds.
