Assets and Robots#
Isaac Sim provides a variety of assets and robots to help you build your virtual world. Some are made specifically for Isaac Sim and robotics applications, others are made for other NVIDIA Omniverse-based applications. The ones that are available to you by default are all located in the Window > Browser tab.
Warning
Assets may take time to load the first time they are accessed. For example, robots may take a few minutes to load, while larger environments may take ten minutes or more.
Hint
The Omniverse Activity UI allows you to monitor the progress and activities when assets are being loaded.
Enable the omni.activity.ui extension in the Extension Manager (Window > Extensions menu),
or launch Isaac Sim from a terminal with the argument --enable omni.activity.ui.
Then, open the Activity Progress window (Window > Utilities > Activity Progress menu) before open/load the USD asset to monitor its loading progress.

Asset Browser vs Content Browser
Content Browser is compatible with Omniverse Nucleus, the database and collaboration engine of Omniverse. However, Omniverse Nucleus is scheduled to be deprecated soon, and the Asset Browser will become the primary way to access assets in Isaac Sim. For Isaac Sim 4.5, Content Browser is still fully functional and can be used to access all Isaac Sim Assets. The Asset Browser is in Beta and is currently setup to be used primarily for browsing USD assets.
