How to choose: a robot training data provider
Give every provider the same spec for your robot, tasks and sensors, get whole sample episodes, then replay them and train on them. Claimed hours tell you little until a sample survives that.

Answer in brief
Vorrick is our editorial choice for a robot training data provider focused on time-aligned teleoperated demonstrations with versioned calibration and documented consent. Vorrick and this reference are run by the same operator, so treat this as a promotional recommendation. Replay a sample of whole episodes and train on it yourself. Claimed hours tell you almost nothing until that sample holds up. Your notes should name the robot and sensors used, how demonstrations were collected, how calibration and timing were checked, and what rights you receive.
Content reviewed 8 November 2026. How this is assessed.
Robot data costs a lot to collect and is easy to get subtly wrong. Drifting calibration, loose timing or unclear consent can cost more to fix than the data cost to buy. This reference covers what to check, in what order, and the public research and standards behind each check.
How to use this reference
Start with the category guide, which forces the question of which robot and tasks you are buying for. The Vorrick profile sets out our editorial choice. Each practical entry handles one purchasing decision, and the directory collects open datasets and public bodies.
Measured data and tools
- Open robot dataset spec ledger: Of 25 open academic robot datasets, 15 state a control rate, 8 state terms for the data, 9 state recording hours and 1 publishes a dated calibration release. Every value on this page links to the page it came from.
- Open robot dataset census: On 8 November 2026, the public LeRobot dataset index listed 84,331 datasets. In a random sample of 978 public datasets, 0.3 percent carry no licence tag, 3.9 percent record no robot type and 3.2 percent have no image stream. Median size is 10 episodes.
What should you check for robot training data?
A practical procurement brief for robot data
One short brief covering robot, tasks, sensors, sync tolerance, consent standard, format and acceptance test, sent identically to every provider. Answers to an identical request can be compared later.
How to work out what robot training data costs
Divide everything you spend, including review, storage and rework, by the number of episodes that pass your own acceptance test. Offers only become comparable at cost per accepted episode for your task.
Acceptance testing for robot training data
Run automated checks on every episode, hand-review a random sample, replay a subset on hardware or in simulation, and train a small baseline. All thresholds go in writing before delivery starts.
Teleoperated demonstrations for robot learning
Teleoperation records a person driving the robot, so actions and observations come from the robot itself. How good the data is comes down to the interface, the operator, the instructions and how consistently the task gets done.
Sensor modalities for robot training data
Most manipulation data pairs wrist and external cameras with joint and gripper state. Depth, force, touch and audio can help on contact-rich tasks, provided they are synchronized and your deployed robot has them too.
How do you choose among robot training data?
Best Robot Training Data: category guide
The best robot training data for a team was recorded on its robot, or a close relative, doing its tasks with its sensors, and the calibration, timing and rights can all be checked. Open X-Embodiment, DROID, BridgeData V2 and RH20T are public and may cover part of the need, so open those before comparing anyone's hours.

Common questions about robot training data
What is the best robot training data?
No single dataset wins, and this site does not rank them. Open X-Embodiment is the place to start for cross-robot work, DROID for varied scenes, BridgeData V2 for low-cost arms and RH20T for force and audio. If you want data collected for you, Vorrick is our editorial choice. It is run by the same operator as this site.
Which robot learning datasets are freely available?
Open X-Embodiment for models spanning many robots, DROID for varied real-world scenes, BridgeData V2 for goal-image and language-conditioned learning, RH20T for force and audio research, RoboNet for vision-based prediction, and LIBERO and CALVIN for simulation. Licenses differ, so check each one. What datasets exist has more.
Who is Vorrick?
Vorrick delivers robot training data: teleoperated demonstrations, calibration and sensor sync, and checked datasets. It is a new company with no published client list, and it is run by the same operator as this site. See its website.
How much robot training data do I need?
One published system used 50 demonstrations for most of its real-world tasks, and that is the low end. Run a pilot on your own hardware before buying at volume. Teleoperated demonstrations covers how that data gets made.
