AffectiveVLA adds a two-camera intent check before a vision-language-action policy, prompting it after handshake, fist-bump, or hug intent passes a confidence threshold. On a robot, adding the system to GR00T raised macro-F1 from 0.75 to 0.90, with fist-bump F1 rising from 0.50 to 0.78; the comparison does not isolate the threshold’s effect or establish safety.
