China’s top robot dog maker built on US Army research

China's Unitree Robotics based designs for its most successful robot dogs on innovations funded by the U.S. military, according to a Reuters ↗ 2.56% investigation published Tuesday that detailed for the first time the connections between U.S. Army research and the Chinese company's rapid rise to dominate the global quadruped robot market.kfgo+1

Unitree's $1,600 Go2 model, launched in 2023, drew on breakthroughs in quadruped movement financed by the U.S. DEVCOM Army Research Laboratory and other military programs, according to a former U.S. defense technology official and three researchers involved in the project.reuters+1

From Army Lab to Chinese Factory Floor

The Army-funded Robotics Collaborative Technology Alliance, which ran from 2010 to 2020, gathered researchers from the University of Pennsylvania, MIT, Boston Dynamics, NASA's Jet Propulsion Laboratory, and other institutions. In 2016, UPenn researchers eliminated heavy central gearboxes and placed motors directly in robots' legs. MIT's lab then built on that work to produce the Mini Cheetah in 2019.kfgo

"Basically, the first Unitree robot that had any kind of scale" came from the Army-funded project, said Gavin Kenneally, a former UPenn researcher who commercialized the breakthroughs through his company Ghost Robotics. Ben Katz, who worked at MIT's Biomimetic Robotics Lab, said the dimensions of Unitree's Go series were "to the millimeter" almost identical to the Mini Cheetah.reuters+1

Unitree founder Wang Xingxing cited MIT's work in his 2016 master's thesis and referenced Kenneally's ARL-funded paper. Within six months of Katz publishing his thesis detailing Mini Cheetah's actuators, Chinese companies were manufacturing copies available on AliExpress.kfgo

A Broader Competition

The episode underscores the United States' struggle to commercialize its own research against China's state-directed manufacturing apparatus. Unitree sold more than 5,500 humanoids and 18,000 quadrupeds last year, and is valued at about $9 billion ahead of its Shanghai IPO on Wednesday. No U.S. company has mass-produced such robots.moderndiplomacy+3

The Trump administration moved in July to ban imports of future Chinese humanoid and quadruped robots, and the Pentagon added Unitree to a list of Chinese military companies in June. But researchers said trade barriers alone are insufficient.kfgo+1

"This isn't just a competition between U.S. and Chinese robotics companies," Kenneally said. "It's between private U.S. companies and China's coordinated national strategy."kfgo
