# Teaching a robot from demonstrations

OpenVLA gives robotics teams a pretrained vision-language-action model plus instructions for fine-tuning it on their own robot demonstrations.

Format: discovery
Source publication: 2024-06-13
Bright publication: 2026-09-19
Substantive update: None recorded
Evidence and review: Experimental; confidence: unassessed; source-checked; ai-assisted. AI-assisted comparison with the cited sources. Source-checked means the record was checked against those sources; it does not claim independent reproduction, expert review, or validation of the publisher’s results.

## The human problem

Every new physical task can demand costly robot data collection and a specialist control pipeline.

## The prior constraint

Robot policies were commonly narrow, hardware-specific, and difficult for outside teams to reproduce or adapt.

## AI’s actual role

The model reads an image and language instruction, then predicts actions for a robot manipulator.

## The documented result

The official release provides checkpoints, LoRA and full fine-tuning paths, configuration files, and evaluation instructions for supported robot environments.

## Why it may matter

A reusable starting policy may let more labs test generalization, while responsibility for physical safety stays with the deploying team.

## Limitations

Repository code is MIT, while checkpoints inherit Llama 2 Community License restrictions. Laboratory evaluations do not establish safe unattended operation.

The repository documents a reproducible research artifact. Its MIT code license does not extend to the released model checkpoints.
