SharpaTacData

Dexterous manipulation data with fingertip tactile sensing from the DextraVerse project (MARS Lab, Nanyang Technological University): a Dexmate Vega dual-arm robot with two 22-DoF SharpaWave hands. Everything is in the Open-X-Tactile format (the FTP-1 zarr layout); the Open-X-Tactile site documents the format and how to load it.

All archives live in DextraVerse/, which holds two sub-datasets:

Folder Data Tasks Episodes Frames Archives
DextraVerse/SharpaTacData.tar real robot 1 (pick up a cube, place it in a box) 261 138,382 SharpaTacData.tar (43 GB)
DextraVerse/<task>.zarr.zip simulation (Isaac) 3 (handover, pick and place, stack cube) 300 135,734 three <task>.zarr.zip (25 GB)

Each sub-dataset has its own README with the array list, conventions and known limitations. The two share the robot, the hand-joint slot assignment and the wrist-frame convention; they differ in sensors (real SharpaWave fingertips versus synthetic deformation maps and PhysX contact forces), cameras and tactile group names. Read the sub-dataset README before mixing them.

SHA256SUMS.txt lists the hash of every archive:

sha256sum -c SHA256SUMS.txt
tar -xf DextraVerse/SharpaTacData.tar        # -> SharpaTacData/pick_cube_place_box.zarr
unzip DextraVerse/handover.zarr.zip          # -> handover.zarr (ZIP64)
