ROS 2 & Robotics Software Engineering Roadmap
Master modern ROS 2 Humble/Iron: Architecture, DDS, Nodes, Services, Actions, Launch, and Simulation.
The industry-standard software framework for autonomous systems, medical robots, and aerospace. Master modern ROS 2 C++ and Python development, node lifecycles, DDS quality-of-service, custom messages, and Gazebo simulation.
Roadmap Curriculum & Milestones
Complete each sequential phase to build production-grade robotics competencies.
Phase 1: ROS 2 Core Architecture & Communication
Master node creation, publishers, subscribers, services, actions, and QoS profiles.
rclcpp & rclpy: Nodes, Topics & Custom Interfaces
Write robust C++ and Python nodes, configure custom .msg/.srv/.action definitions, and manage package dependencies with CMake & colcon.
- Node Composition & Components
- Custom Interface Definition
- colcon build & ament_cmake
- Parameter Callbacks
- Multi-node sensor telemetry pipeline with custom message headers
DDS, Quality of Service (QoS) & Action Servers
Understand Data Distribution Service (DDS), reliability/durability QoS profiles for lossy WiFi, and long-running Action Servers with goal preemption.
- QoS Reliability & Durability Tuning
- Action Server/Client Pattern
- Goal Cancellation & Feedback Streams
- FastDDS / CycloneDDS Config
- Preemptible robot navigation action server with progress feedback
Phase 2: Robot Modeling, TF2 & Gazebo Simulation
Model robot physics with URDF/Xacro, broadcast 3D transforms with TF2, and simulate sensor interactions.
URDF, Xacro & TF2 Coordinate Frame Management
Build modular robot models with Xacro macros, define collision and visual geometries, and manage dynamic transform trees.
- Xacro Parameterization
- Inertial Tensor Calculation
- TF2 Broadcasters & Listeners
- Transform Tolerances & Buffer Lookups
- Complete 4-wheel mobile robot URDF with articulated LiDAR mount
Gazebo Ignition Simulation & ros2_control Framework
Spawn URDF models in Gazebo, configure physics engines (ODE/Bullet), and bridge joints to ros2_control diff_drive and joint_trajectory controllers.
- Gazebo Plugin Development
- ros2_control System Interface
- Controller Manager & Hardware Interfaces
- Gazebo ROS Bridge
- Full physical simulation of an autonomous warehouse robot in a realistic world
