I spent $4,000 on a robot dog from China

Hands-on review finds the $4,017 Unitree Go2 Pro robot dog affordable but impractical, as Unitree reaches a $34 billion valuation after its IPO.

Ars Technica reviewed the Unitree Go2 Pro quadruped, purchased for $4,017, finding it astonishingly cheap but of limited practical use; it collapsed from battery drain and heat (84°C internal temperature) on an uphill walk at 87°F. Unitree democratized quadruped research, sells humanoid robots from $13,500, and debuted on the Shanghai stock exchange on August 19 with shares rising over fivefold on day one, valuing the company at $34 billion. Its robots now face legal restrictions in the United States, and it competes with Boston Dynamics, whose Spot starts around $75,000.

Heart of the Matter: How a Major Children’s Hospital Uses Open Source NVIDIA AI for Cardiac Care

Children's Hospital of Philadelphia uses NVIDIA open-source MONAI, Warp and Newton to build pediatric heart models in seconds for surgical planning.

CHOP's cardiac modeling service uses MONAI, Auto3DSeg and SlicerHeart to turn CT, MRI and 3D ultrasound images into anatomically precise heart models in seconds instead of four hours of manual work. More than 20 US children's hospitals run similar programs, with Boston Children's supporting roughly 500 cardiac surgery cases a year. NVIDIA's Newton physics engine, built on the Warp Python framework, aims to reduce device simulations from hours to near real time in clinical workflows.
