Simple#

The NVIDIA Simple example provides a starting point to experiment with Isaac Robotics.

Vehicle Example#

The basic vehicle example provides a framework for creating mobile platforms.

April Tags#

We provide a simple mdl material that can index into a April Tag mosaic image.

To use, add the material to your stage using Create->April Tag->

Then create a mesh cube using Create->Mesh->Cube and assign the AprilTag material to that prim

The material has the following parameters which need to be configured:

Mosaic texture The path to the texture that contains the grid of April tag images
Tag Size The width/height of the tag in pixels
Tags Per Row The number of tag images per row in the mosaic
Spacing The number of padding pixels between each tag image
Tag ID The index of the tag to use.

The figure below shows example usage using tag36h11.png, after manually creating the mesh cube and assigning the material as described above.
