# AMP Tadpole for LeRobot

The weights of [AMP Tadpole](https://huggingface.co/Adaptive-Machine-Patterns/amp-tadpole)
v0.2.0 in LeRobot's format, for the `tadpole` policy type from
[lerobot-policy-tadpole](https://github.com/Adaptive-Machine-Patterns/lerobot-policy-tadpole).

AMP Tadpole is a small vision-language-action model (6.5M parameters) that drives a
six-joint arm from three fixed camera images, the arm's state and a plain-English
instruction, trained from scratch on the
[AMP Toy Robotics Benchmark](https://github.com/Adaptive-Machine-Patterns/amp-toy-robotics)
(93.7% of instructions on its 300 held-out scenes). Its results, training, limitations
and credits are on [the main model card](https://huggingface.co/Adaptive-Machine-Patterns/amp-tadpole).

## Use

```bash
pip install git+https://github.com/Adaptive-Machine-Patterns/lerobot-policy-tadpole
```

```python
from lerobot_policy_tadpole import TadpolePolicy, make_tadpole_pre_post_processors

policy = TadpolePolicy.from_pretrained("Adaptive-Machine-Patterns/amp-tadpole-lerobot")
pre, post = make_tadpole_pre_post_processors(policy.config)
```

or `--policy.path=Adaptive-Machine-Patterns/amp-tadpole-lerobot` with LeRobot's tools.

## What is in it

The same network and weights as the main repository's v0.2.0 (step 330,000), and it gives
the same answers: checked on 36 held-out observations through LeRobot's own processors,
with no difference. Two parts used only in training are kept, so it can be fine-tuned:
the head with which each image token redraws its patch, and the "no state" token. That
makes 6,557,191 parameters. The word table holds the 32 tokens of the benchmark's
instructions, plus one shared row for any other word.
