Integration solution

All the data was collected on a WidowX 250 6DOF robot arm.

Verified on: 2026-10-19

Scope: Research configuration for WidowX; the cited checkpoint is a WidowX fine-tune, not a factory installation claim for the base model.

Conditions: Uses the documented X-VLA WidowX checkpoint and BridgeData V2-compatible configuration.

Integration solution

The resulting architecture — X-VLA-0.9B — achieves state-of-the-art generalization across six simulation platforms and three real-world robots. X-VLA-WidowX: Fine-tuned on BridgeDataV2 (Simpler benchmark).

Verified on: 2026-10-19

Scope: Platform identification for the documented research configuration.

Conditions: Applies to BridgeData V2.

Integration solution

All the data was collected on a WidowX 250 6DOF robot arm.

Verified on: 2026-10-19

Scope: Simulation/research configuration for WidowX; it does not claim factory installation or real-robot safety validation.

Conditions: Requires the documented SimplerEnv setup and the VLA-JEPA-Simpler checkpoint.

Integration solution

The VLA-JEPA repository provides the VLA-JEPA-Simpler.pt checkpoint for SimplerEnv evaluation; bridge_put_on corresponds to the WidowX robot evaluation.

Scope: WidowX research integration after fine-tuning; this is not a factory installation or zero-shot performance claim for the base checkpoint.

Conditions: Requires a compatible WidowX/Bridge setup and a target-domain fine-tuned Octo checkpoint.

Integration solution

The Octo repository documents fine-tuning from hf://rail-berkeley/octo-small-1.5 and includes an Octo Robot Eval example for evaluating a finetuned Octo model on a real WidowX robot.

Verified on: 2026-10-19

Scope: Research real-robot evaluation on the named WidowX 250 S platform; not a factory-installation, safety-certification, or general deployment claim.

Conditions: Applies to the task suites and experimental configuration reported in the paper.

Physical verification

The EO-1 paper reports real-world evaluation on WidowX 250 S, including 13 out-of-box kitchen tasks and instruction-following evaluation across 15 tasks.
