One GPU, 2,048 Simulated Robot Arms: Inside NVIDIA's Walkthrough of MuJoCo Warp for Hobbyist-Grade Robotics

A September 23, 2026 NVIDIA tutorial on Hugging Face walks through moving an open SO-101 robot arm scene from CPU-based MuJoCo to up to 2,048 parallel simulated worlds on one GPU using MuJoCo Warp. Here is what the walkthrough does and does not show, explained for non-specialists.

BRIDGE Designs a Humanoid Body and Controller as One System

The compact research robot links morphology, actuator limits and learned control, but its strongest comparisons remain simulated and its full open-source release is still pending.

RoboRMBench Exposes Wording-Sensitive Reward Scores in Robot Learning

A new preprint tests vision-language reward models on 2,390 recorded real-robot trajectories and finds that equivalent instructions can produce contradictory judgments, revealing a measurable reliability gap before physical deployment.
