Copyright (c) Neobotix GmbH
Licence: BSD, as declared in the package manifest (no licence text ships upstream).
Converted (and, where the source is heavy, decimated) to OBJ in metres by
external/convert/build_scanner_devices.py; the MJCF's link frame, visual origin, collision
primitive and inertial are read from the same repository.

--------------------------------------------------------------------------------

The repository ships no LICENSE file, and the mesh carries no per-file copyright header. The only
licence statement the upstream makes is the one in the package manifest that ships the mesh:

    rox_description/package.xml, at the commit above

      <maintainer email="ros@neobotix.de">Neobotix</maintainer>
      <license>BSD</license>
      <author email="padmanabhan@neobotix.de">Pradheep Padmanabhan</author>

"BSD" names a family, not a document: the 2-clause, 3-clause and original 4-clause texts differ in
what they require. No variant's text is reproduced here, because choosing one would put terms in the
licensor's mouth that the licensor did not write. What every variant does require -- that the
copyright notice and the licence statement travel with the copy -- is what this file is: it names the
copyright holder, the author, the exact upstream revision, and the exact file the geometry derives
from.

If a downstream use needs the variant pinned (an SPDX-clean SBOM, say), ask Neobotix GmbH to state
it, and replace this paragraph with their answer.
