Dataset Viewer

The dataset viewer is not available because its heuristics could not detect any supported data files. You can try uploading some data files, or configuring the data files location manually.

convert_to_lerobot

This script generates a ready-to-use LeRobot dataset repository from RoboChallenge dataset.

Prerequisites

  • Python 3.9+ with the following packages:
    • lerobot
    • opencv-python
    • numpy
  • Configure $LEROBOT_HOME (defaults to ~/.lerobot if unset).
pip install lerobot opencv-python numpy
export LEROBOT_HOME="/path/to/lerobot_home"

Usage

Run the converter from the repository root (or provide an absolute path):

python convert_to_lerobot.py \
  --repo-name example_repo \
  --raw-dataset /path/to/example_dataset \
  --frame-interval 1 

Output

  • Frames and metadata are saved to $LEROBOT_HOME/.
  • At the end, the script calls dataset.consolidate(run_compute_stats=False). If you require aggregated statistics, run it with run_compute_stats=True or execute a separate stats job.
