A Survey on Robot Semantic Navigation Systems for Indoor Environments

Abstract

Robot autonomous navigation has become a vital area in the industrial development of minimizing labor-intensive tasks. Most of the recently developed robot navigation systems are based on perceiving geometrical features of the environment, utilizing sensory devices such as laser scanners, range-finders, and microwave radars to construct an environment map. However, in robot navigation, scene understanding has become essential for comprehending the area of interest and achieving improved navigation results. The semantic model of the indoor environment provides the robot with a representation that is closer to human perception, thereby enhancing the navigation task and human–robot interaction. However, semantic navigation systems require the utilization of multiple components, including geometry-based and vision-based systems. This paper presents a comprehensive review and critical analysis of recently developed robot semantic navigation systems in the context of their applications for semantic robot navigation in indoor environments. Additionally, we propose a set of evaluation metrics that can be considered to assess the efficiency of any robot semantic navigation system.

Bridging Requirements, Planning, and Evaluation: A Review of Social Robot Navigation

“…A leading approach to enable the robot's contextual awareness is semantic mapping [224][225][226]. For example, Zhang et al [227] used an object semantic grid map along with a topological map for the automatic selection of roughly defined navigation goals in a multiroom scenario.…”

ZUST Campus: A Lightweight and Practical LiDAR SLAM Dataset for Autonomous Driving Scenarios

“…Other datasets that contain LiDAR measurements either focus on other tasks, e.g., object detection and semantic segmentation [17], or are based on simulations. The InLiDa dataset [18] focuses on indoor environments, and uses 3D LiDAR to detect and segment indoor pedestrians and track them.…”

Design and Experiment of an Agricultural Field Management Robot and Its Navigation Control System

“…The navigation system we designed integrates a low-cost RTK-GNSS receiver, IMU sensor, and 16-line lidar. Navigation software (Version: 1.20.0) is developed based on the existing ROS open-source software framework (Version: 1.0) [22], which can control the robot to avoid obstacles and control the robot to move along the set path or crop line. The robot positioning program adopts the EKF package, which combines GPS odometer data with the attitude data from the IMU (inertial measurement unit) to estimate the position and attitude of the robot.…”
