چکیده

The advent of spacecraft mobile robots—free-flying sensor platforms and communications devices intended to accompany astronauts or remotely operate on space missions inside and outside of spacecraft—has demanded the development of a simple and effective navigation. One such system under exploration involves the use of a lasercamera arrangement to predict relative positioning of the mobile robot. By projecting laser beams from the robot, a 3D reference frame can be introduced. Thus, as the robot shifts in position, the position reference frame produced by the laser images is correspondingly altered. Using normalization and camera registration techniques presented in this paper, the relative translation and rotation of the robot in 3D are determined from these reference frame transformations.

Navigation of a Mobile Robot Using Virtual Potential Field and Artificial Neural Network

Mobile robot navigation is one of the basic problems in robotics. In this paper, a new approach is proposed for autonomous mobile robot navigation in an unknown environment. The proposed approach is based on learning virtual parallel paths that propel the mobile robot toward the track using a multi-layer, feed-forward neural network. For training, a human operator navigates the mobile robot in ...

Using Model-Based Localization with Active Navigation

Vision is an important sensor used for mobile robot navigation. One approach to localization which is based on vision is to compute camera egomotion with respect to base images. What characterizes this method of localazation is that its performance varies greatly in different positions. Active navigation is an approach to path and sensing planning which is designed to address varying performanc...
