LiDAR for Mobile Robots: Using Laser Sensors to Help Your Robot See Walls, Doorways, and Obstacles in the Dark

Give your robot the ability to see, understand, and navigate the world around it.Modern mobile robots rely on accurate perception to move safely through homes, warehouses, offices, and outdoor environments. LiDAR technology has become one of the most powerful sensing solutions for helping robots detect walls, recognize obstacles, measure distances, and build maps-even in low-light or completely dark conditions.LiDAR for Mobile Robots is a practical beginner-friendly guide that explains how laser sensors work and how they are used to create smarter autonomous robots. Whether you are a robotics student, engineer, hobbyist, or developer exploring autonomous navigation, this book provides a clear path from fundamental concepts to real-world applications.Inside this book, you will learn: - How LiDAR sensors measure distance using laser pulses- The differences between 2D and 3D LiDAR systems- How robots use laser scans to detect walls, doors, furniture, and obstacles- Sensor installation, calibration, and data collection techniques- How LiDAR supports mapping and localization for autonomous navigation- The basics of SLAM (Simultaneous Localization and Mapping)- How mobile robots combine LiDAR with cameras, IMUs, and other sensors- Common LiDAR challenges, limitations, and troubleshooting methods- Practical applications in warehouse robots, delivery robots, service robots, and autonomous machinesWritten with clarity and practical examples, this book helps readers understand how robots transform raw laser measurements into intelligent decisions. By the end, you will have a solid foundation in using LiDAR sensors to design robots that can navigate confidently, avoid collisions, and operate in complex environments.Start building robots that can see beyond ordinary vision-using the power of LiDAR.
