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.
