[0002] With the continuous development of robot technology, the application of autonomous mobile robots in home scenes has received increasing attention. Especially for intelligent interactive service robots, people have higher expectations and pursuits for their functions and performance. In this context, the research on autonomous mobile robots has become one of the important research directions in the field of artificial intelligence. The technology involved in this utility model covers multiple fields such as speech recognition, robot control technology, visual recognition and robot navigation. Navigation technology is one of the key technologies, and its core includes key technologies such as environmental perception, path planning, positioning and navigation control. In terms of environmental perception, the robot uses sensors such as laser radar and cameras to perceive the surrounding environment in real time, identify and track the position and movement of obstacles. The path planning algorithm is based on the environmental map and the target position, and determines the optimal path of the robot by considering factors such as obstacle avoidance and travel efficiency to achieve safe and efficient navigation. Positioning technology achieves accurate positioning of the robot in a complex environment by integrating multiple sensor data, such as inertial navigation, GPS and visual positioning. The navigation control algorithm adjusts the speed and steering of the robot in real time according to the path planning and positioning information to ensure that the robot reaches the target position safely along the planned path. By combining these technologies, autonomous mobile robots can navigate autonomously in various complex environments and perform various tasks, such as cargo transportation, personnel guidance, emotional communication, and companionship for the elderly, providing intelligent navigation services for families and other scenarios, and improving users' quality of life and work efficiency.
