End-to-End Navigation Model Training with Isaac Sim, MobilityGen, and Cosmos Augmentation

This tutorial walks through a complete workflow for building a navigation model using Isaac Sim and MobilityGen to generate synthetic data, applying Cosmos‑Transfer1‑7B for visual data augmentation, training the X‑Mobility model via imitation learning, converting it for ROS2 deployment, and performing software‑in‑the‑loop validation.

How Robots Navigate Homes: Inside the Nav2 Autonomous Navigation Framework

Robotic vacuum cleaners use SLAM to map unknown homes, then rely on the ROS 2 Nav2 framework—comprising global and local planners, controllers, smoothers, and AMCL localization—to plan optimal paths, avoid dynamic obstacles, and generate velocity commands, with algorithms like Dijkstra, A*, DWA, and TEB explained.
