Action Chunking with Transformers (ACT) is an imitation-learning method that predicts short action chunks instead of single steps. It learns from teleoperated data and often achieves high success rates.
This policy has been trained and pushed to the Hub using
LeRobot.
Learn how to train and run it in the
LeRobot act guide, or browse the
full documentation.
The policy consumes these observation features and produces these action features.

When
--strategy.type=base is used the script doesn't record the episodes. Skipping duration will make the policy run indefinitely. For more information look at
rollout documentation.
