HARP-VLA: Human-Robot Aligned Representation Learning for Vision-Language-Action Model
Paper • 2605.31234 • Published
Merged HARP-VLA policy for CALVIN evaluation.
Use the official inference code to load this checkpoint. The vision adapters are included in the merged weights and installed by the HARP-VLA model loader.
python examples/download_checkpoint.py
python -m experiments.robot.calvin.evaluate \
--pretrained_checkpoint checkpoints/calvin \
--calvin_root "$CALVIN_DATA_ROOT"
The policy consumes static and gripper camera images and seven-dimensional proprioception. It predicts ten seven-dimensional relative actions per inference call. Use center cropping and the supplied normalization statistics.
Built upon OpenVLA-OFT and UniVLA. Evaluation uses CALVIN.
