Landmark recognition is identified as one important research area in robot navigation systems. It is a key feature for building robots capable of navigating and performing tasks in human environments. However, current object recognition research largely ignores the problems that the mobile robot context introduces. We developed a landmark recognition system which is used by a humanoid robot to identify...
This article introduces a prototype of the mobile device intended for interoperation transport in outdoor environment. The interoperation transport between production and montage halls is its main function. The mobile robot is protected against damage at forward and backward movement.
In robotics, vertical lines have been always very useful for autonomous robot localization and navigation in structured environments. This paper presents a robust method for matching vertical lines in omnidirectional images. Matching robustness is achieved by creating a descriptor which is very distinctive and is invariant to rotation and slight changes of illumination. We characterize the performance...
An algorithm is proposed to answer the challenges of autonomous corridor navigation and mapping by a mobile robot equipped with a single forward-facing camera. Using a combination of corridor ceiling lights, visual homing, and entropy, the robot is able to perform straight line navigation down the center of an unknown corridor. Turning at the end of a corridor is accomplished using Jeffrey divergence...
This paper presents a Web-based remote laboratory that gives remotely located students the opportunity to experiment different navigation algorithms on a mobile robot connected to Internet. The e-learning system consists of a Web interface that allows uploading the program to the mobile robot, access the on-board video camera and monitor different state variables.
This work addresses the use of optical flow to supervise the navigation of mobile robot. The optical flow information is computed from the images sequence in order to be used in the navigation algorithm. The optical flow provides very important information about the robot environment, like: the obstacles disposition, the robot heading, the time to collision and the depth. The use of this information...
This paper presents the development of a visual-based fuzzy navigation system that enables a mobile robot in moving through a corridor or following a wall. The system employs a camera to detect the existence of walls on the left, the right, and the front of the robot. A mamdani-type fuzzy logic controller uses the information gathered by the camera to determine the turning angle and the speed of the...
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,...
