NIST Assembly Task Board 1 — USD Assets

This release contains USD-format assets for Task Board 1 of the NIST Assembly
Task Boards, with SDF colliders suitable for physics simulation (e.g. Isaac Sim /
Isaac Lab).

Contents

  • All parts from Task Board 1 (board, plugs, sockets, fasteners) in USD format
  • SDF colliders for every part, authored to support stable contact and assembly
  • Plugs verified to fit their corresponding sockets in simulation

Provenance

The source STL meshes were originally published by NIST as part of the Robotic
Grasping and Manipulation Assembly benchmark:

https://www.nist.gov/el/intelligent-systems-division-73500/robotic-grasping-and-manipulation-assembly/assembly

The original collision meshes from that source exhibit self-interpenetration,
which makes them unreliable for contact-rich manipulation tasks. For this
release, every asset was manually repaired and re-authored so that:

  • Collision geometry no longer interpenetrates
  • All plug/socket pairs assemble cleanly end-to-end
  • Each task-board interaction works as expected in simulation

Credits

These assets were created by Octi Zhang while a student at the
University of Washington, with contributions from fellow UW students:

  • Alex Zhang
  • Xinlei Liu
  • Rosario Scalise

We thank them for their help in preparing and validating these assets.

public domain as works of the U.S. federal government; this release covers only
the repaired/authored USD + SDF assets.
