Project-Group-Based Experimental Teaching Design for Intelligent Robot Navigation

摘要: 随着人工智能、机器视觉与移动机器人技术的发展，机器人智能导航实验教学的重要性日益突出。针对当前教学中存在的实验内容衔接不够紧密、学生难以形成系统认知与综合应用能力等问题，本文提出了基于项目群的机器人智能导航实验教学设计。依托二轮差速移动机器人实验平台，构建集嵌入式控制、视觉感知、激光雷达测距与ROS2导航环境于一体的实验系统，并设置机器人硬件平台构建与运动控制、视觉AI感知与仿真验证以及机器人导航与路径规划三个递进式实验项目。该设计将底盘运动控制、障碍物识别、环境感知、路径规划与避障等内容有机融合，有助于提升学生的系统认知、工程实践与综合应用能力，对机器人课程实验教学改革具有参考价值。

Abstract: With the development of artificial intelligence, machine vision, and mobile robotics, the importance of experimental teaching for intelligent robot navigation has become increasingly prominent. To address current problems in teaching, such as insufficient coherence among experimental contents and students’ difficulty in developing systematic understanding and comprehensive application abilities, this paper proposes a project-group-based experimental teaching design for intelligent robot navigation. Relying on a two-wheeled differential mobile robot platform, an experimental system integrating embedded control, visual perception, LiDAR ranging, and a ROS2 navigation environment is constructed. On this basis, three progressive experimental projects are designed, namely robot hardware platform construction and motion control, visual AI perception and simulation verification, and robot navigation and path planning. This design organically integrates chassis motion control, obstacle recognition, environmental perception, path planning, and obstacle avoidance, which helps improve students’ systematic understanding, engineering practice ability, and comprehensive application capability, and provides a useful reference for the reform of robotics-related experimental teaching.
