RLDS

Reinforcement Learning Datasets — an episodic format for robot learning data.

Definition

RLDS (Reinforcement Learning Datasets) is a standard for storing episodic, step-based data for robot learning, built on TFDS. It represents each demonstration as a sequence of steps with observations and actions, which makes egocentric episodes portable across training pipelines.

01

Why it matters

A common episodic format means you can mix datasets and reuse dataloaders instead of writing bespoke parsers. RLDS is widely used across open robot-learning efforts.

How Firsthand handles it

Firsthand delivers in RLDS with readable converter source, so you can retarget the field mapping to your own loader rather than trusting a binary.
