768 tiny open-source robots simulated in one hospital ward on a single GPU

A large-scale robot simulation demo: 256 copies of an ICU bay built from the open SimReady hospital asset set (CC BY 4.0), each holding 3 Microducks from Pollen Robotics — 768 robots total on one GPU. After 14 seconds of full physics rollouts, 766 of 768 stayed upright. Compute cost: 478 s of compute for 14 s of simulated time. The author argues this parallel simulation approach is how hospital robots will learn before ever meeting a patient.
