Reliable navigation of a low-cost mobile robot in an indoor environment can prove to be challenging as position fixing sensors, such as a GNSS receiver, are typically unavailable. Subscribing to the premise of a baseline of odometry and inertial sensors, this paper compares three navigation strategies, namely, a full 6-DOF inertial measurement unit (IMU) with kinematic constraints, a partial IMU with...
Localization and mapping is important in autonomous navigation of mobile robot. In this paper, we deal with localization using 2D laser range finder and IR positioning sensor. 2D grid map is built in local coordinate using data from laser range finder. And it is integrated into global coordinate using information from IR landmark. It can provide consistent global map that can be used in the autonomous...
Research in the areas of localization, mapping and path planning for single mobile robots has been carried out extensively. Nevertheless, relatively little of its work is applied to multiple robot systems. Moreover, when these robots coexist with human, complex and unpredictable human environments make the above navigational tasks even more challenging. To address this problem we propose intelligent...
Simultaneous Localization and Mapping (SLAM) addresses the problem of a robot navigating and acquiring spatial models of initially unknown environments, without an absolute localization means. To solve this problem, we propose a mapping system that builds feature-based geometrical maps by applying a modified Particle Swarm Optimization (PSO) algorithm. Particles are defined as the location of individual...
The research presented introduces a new methodology to infer environment structure and robot localization by using a monocular machine vision system. The local field of view is constrained to the vicinity of the mobile robot in order to accomplish with robust navigation issues. The strategy proposed uses optical flow techniques and planar models to obtain qualitative 3D information and robot localization...
In localization technology for a mobile robot, visual locating is widely concerned because of its high precision and large amount of information, et al. Firstly, the paper introduces some popular locating methods and shows the advantages and disadvantages. Secondly, it discusses some technology related to distance measurement in visual locating, such as image segment, feature matching, camera calibration,...
