移动机器人在各种辅助任务中需具备自主定位、建图、路径规划与运动控制的能力。本文利用RGB-D信息和ORB-SLAM算法进行自主定位,结合点云数据和GMapping算法建立环境栅格地图,基于二次规划方法进行平滑可解析的路径规划,并设计非线性控制器,实现了由一个运动底盘、一个RGB-D传感器和一个运算平台组成的自主移动机器人系统。经实验验证,这一系统实现了复杂室内环境下的实时定位与建图、自主移动和障碍物规避。由此,为移动机器人的推广应用提供了一个硬件结构简单、性能良好、易扩展、经济性好、开发维护方便的解决方案。

To accomplish various tasks, mobile robots need the capabilities of autonomous localization, mapping, path planning, and motion control. In this paper, an autonomous robot system was realized using a mobile platform, an RGB-D sensor, and a computing unit. Localization was achieved using the ORB-SLAM algorithm based on RGB-D information, and the 2D grid map was built-up using the GMapping algorithm with localization and point cloud data. A smooth path was produced by point generation and curve fitting with quadratic programming. The robot motion was regulated by a nonlinear controller. The proposed system and methods were validated by experiments and the results show that the system can realize real-time localization and mapping, autonomous movement, and obstacle avoidance in a complex indoor environment. Therefore, the research provides a solution with the following merits for promotion and application of mobile robots:simple hardware structure, excellent performance, easy extension, as well as economical and convenient development and maintenance.
