Researchers released 3,718 real-robot episodes from the ArmnetBench v0.1 evaluation on the Hugging Face Hub, according to a preprint. The corpus includes 600 teleoperated demonstrations and 3,118 rollouts from seven policies tested on 12 tabletop tasks using low-cost SO-101 robot arms.

Each episode contains three camera views, joint states and actions, with data available in LeRobot v3.0 and a reward-model format. An operator labelled each rollout successful, suboptimal or failure; 73% of rollouts are failures. For each task, every policy used the same 50 training demonstrations and ran on the same cell, providing failures across policies under shared conditions.
