Micro-ROS in Practice: Build and Control Real Robots Using ROS 2, micro-ROS, Sensors, and Embedded C/C++ - Tapa blanda

Sinopsis

Build real robots with ROS 2 and micro-ROS—and turn embedded hardware into a powerful part of the modern robotics ecosystem.

ROS 2 is powerful. Microcontrollers are everywhere. But connecting the two and making them work reliably with real sensors, motors, encoders, and physical hardware requires more than simply writing a few nodes.

Micro-ROS in Practice takes you across that gap.

This practical, hands-on guide shows you how to build ROS 2-connected robotic systems using microcontrollers, micro-ROS, embedded C/C++, sensors, actuators, and real-world communication. Instead of focusing only on theory, you will progressively build the knowledge needed to make physical robots sense, communicate, move, and respond.

• Understand the architecture connecting microcontrollers, micro-ROS, the Agent, DDS-XRCE, and ROS 2
• Set up a practical micro-ROS development environment
• Create publishers, subscribers, services, timers, and embedded nodes
• Work with executors, timing, memory, CPU, and resource constraints
• Connect GPIO, ADC, I2C, SPI, and UART sensors
• Control motors, servos, and actuators using PWM and motor drivers
• Implement closed-loop speed and position control
• Build a ROS 2-connected differential-drive mobile robot
• Use serial, UDP, and wireless communication with micro-ROS
• Diagnose transport, communication, node, topic, and hardware failures
• Read wheel encoders and calculate robot odometry
• Publish robot state and sensor data into ROS 2
• Build obstacle detection and reactive robot behaviors
• Integrate embedded control with higher-level ROS 2 navigation
• Debug and optimize embedded robotic software for reliable operation

Working with a physical robot introduces problems that simulations cannot fully reproduce: limited memory, timing constraints, noisy sensors, communication failures, motor behavior, electrical issues, and hardware limitations.

This book teaches you how to approach those challenges systematically. You will learn to view the robot as an integrated system—from sensors and firmware to transport, the micro-ROS Agent, ROS 2 nodes, actuators, and higher-level autonomy.

You will also develop a practical debugging mindset that helps you identify whether a problem originates in the hardware, transport layer, micro-ROS session, ROS 2 communication, or application itself.

Micro-ROS in Practice is ideal for:

• Robotics and embedded systems engineers
• ROS 2 developers moving toward physical robots
• Embedded C/C++ developers entering robotics
• Students and advanced learners studying robotics and autonomous systems
• Makers building sensor- and motor-based robots
• Developers who want practical experience with micro-ROS and ROS 2 integration

You do not need to be an expert in every area of robotics. The book builds progressively, starting with communication fundamentals and moving toward sensors, motor control, odometry, autonomous behavior, debugging, and production-oriented architecture.
