Ars Technica tested a $4,017 quadruped robot from Chinese manufacturer Unitree, illustrating how rapidly falling hardware prices are changing the robotics landscape. While the quadruped successfully walked two miles on a single charge, it suffered performance limitations, eventually collapsing from high internal temperatures and low battery during an uphill walk in 87°F heat. The testing underscored that while practical everyday applications for quadrupeds remain limited compared to wheeled or flying alternatives, low pricing is making the technology broadly accessible.
Unitree has used its quadruped manufacturing experience to expand into humanoid robotics, launching its first humanoid model in 2023. By offering humanoid units for as low as $13,500, the company has established itself as a global leader in low-cost robotics. Reflecting market enthusiasm for its commercial expansion, Unitree officially debuted on the Shanghai stock market on August 19.
Why it matters
Unitree is dramatically reducing capital costs for quadruped and humanoid hardware, lowering entry barriers for robotics startups and research labs.
Thermal management and battery life remain critical engineering bottlenecks for deploying quadruped hardware in demanding real-world environments.
