Sensors Tier#

The Sensors tier supplies the requirements, capabilities, feature contracts, profile contracts, and static validation rules for physics sensors, RTX LiDAR, and camera/render-product workflows. Its sensor profiles apply alongside an asset’s primary profile (Robot-Body, Prop, fixed-mount, etc.); validating a sensor-bearing asset typically requires installing both this tier and the Core tier.

Install the validator and tier together:

pip install simready-validate simready-foundation-tier-sensors

Install the optional Benchmark framework and Kit engine dependencies needed to execute this tier’s bundled runtime tests. This extra requires Python 3.12; validator-only tier installs also support Python 3.11.

pip install "simready-foundation-tier-sensors[benchmark]"

The tables below reflect the catalogs in the current source tree. The tier’s feature JSON and profile TOML files remain the machine-readable sources of truth.

Profiles#

The Sensors tier owns four profiles. Each applies to any asset carrying the corresponding sensor type, independent of the asset’s primary profile (Robot-Body, Prop, fixed-mount, etc.). An asset with multiple sensor types should be stamped with each applicable profile.

Profile	Available versions	Catalog file
Sensor-IMU	`1.0.0`	`profiles.toml`
Sensor-Joint	`1.0.0`	`profiles.toml`
Sensor-Camera	`1.0.0`	`profiles.toml`
Sensor-LiDAR	`1.0.0`	`profiles.toml`

Features#

The Sensors tier owns four feature IDs and four exact feature versions.

Feature	Purpose	Available versions
FET_034_ISAAC	IMU Sensor	`0.1.0`
FET_035_RTX	Camera and Render Products	`0.1.0`
FET_036_RTX	RTX Sensors (LiDAR)	`0.1.0`
FET_037_ISAAC	Joint Sensor	`0.1.0`

Package contents and discovery#

The distribution advertises both the usd_validation_nvidia and simready.tier entry-point groups. Together they expose:

Capability and requirement documentation plus registered validators.
Generated requirement enums.
Feature JSON and profile TOML catalogs.
Tier-owned Benchmark runtime tests for the physics-sensors, render-products, LiDAR, and joint-sensor features.
