About this app

Learn how the ROS 2 Navigation2 stack fits together—without needing a robot, ROS installation, or account.

Nav2 Visual Mastery is a standalone educational app from Academy4Tech. It combines a structured offline curriculum with interactive visual labs that make navigation concepts easier to inspect and understand.

Explore:
• 18 guided lessons covering ROS 2 graph basics, robot-ready inputs, first navigation missions, mapping and localization, Nav2 architecture, lifecycle, behavior trees, costmaps and zone filters, planning, control, motion safety, docking, task servers, actions, transforms, and QoS
• 9 deterministic visual labs for experimenting with core navigation concepts
• An interactive architecture map with component details and animated signal flow
• A 20-question scenario quiz, 30 spaced-repetition flashcards, 39 searchable glossary terms, bookmarks, and local progress
• A personalized, performance-based course-completion certificate generated locally and shared as a PDF only when you choose
• Planner and controller comparisons, footprint and inflation experiments, TF diagnosis, and action-feedback visualizations
• A capstone report builder and 3 local Python/C++ coding exercises with structural checks
• Light, dark, high-contrast, larger-text, and reduced-motion settings

Core lessons, labs, quizzes, drafts, progress, certificate scoring, and certificate generation work offline. The certificate display name and award record stay in app-private storage, subject to Android backup; a PDF leaves the app only through a share action you choose. Advertising, consent checks, and links that you choose to open require internet access.

This app is a learning and visualization tool. It does not connect to, command, monitor, or validate a physical robot, and it does not execute uploaded code. Always verify robot configuration and safety behavior on a controlled test platform.

Nav2 Visual Mastery is an independent Academy4Tech educational project. It is not an official Open Navigation or Open Robotics product.
