3D understanding of the surrounding world is one of the key prerequisites for building truly foundational robotics models. In this demonstration, we will present to the audience some of the latest technologies that address this challenge. The presentation will have the form of the interactive demo (details in the "Live Action" section below). We will show in particular how to efficiently process massive point clouds with hundreds of thousands of nodes and how to integrate powerful invariances and equivariances into modeling to enhance 3D understanding.
