mobile robot navigation is one of the basic problems in robotics. in this paper, a new approachis proposed for autonomous mobile robot navigation in an unknown environment. the proposedapproach is based on learning virtual parallel paths that propel the mobile robot toward the trackusing a multi-layer, feed-forward neural network. for training, a human operator navigates themobile robot in some...

Today robotic creatures’ development has been utilized for several purposes. There have been inventions about animalliked aquatic robots, however few works were found relating to the study of full behavioral movement of aquatic animals; anguilliform, carangiform, subcarangiform and thunniform. This paper presents a study and design of a robotic fish that simulate locomotion pattern of aquatic a...

Online trajectory generation for robots with multiple degrees of freedom is still a difficult and unsolved problem, in particular for non-steady state locomotion, that is, when the robot has to move in a complex environment with continuous variations of the speed, direction, and type of locomotor behavior. In this article we address the problem of controlling the non-steady state swimming and c...

Toward adaptive underwater locomotion, this paper presents the experimental results of a fish-like swimming robot that we have newly developed. By using motor control with only one degree of freedom, this robot exhibits surprisingly rich behavioral diversity in three dimensional underwater environment. This paper focuses on some of the behavior variations this robot exhibits, i.e. forward, turn...

The paper deals with recognition of artificial landmarks using fish-eye lens. The proposed recognition model is based on algebraic affine moment invariants (AMIs). Landmarks are used for the navigation of an autonomous robot, equipped with a fisheye lens camera. The recognition ability of the AMIs regarding the deformation introduced by the fish-eye lens image acquisition is investigated. The r...

as a robot could be stable statically standing on three or more legs, a six legged walking robot can be highly flexible in movements and perform different missions without dealing with serious kinematic and dynamic problems. an experimental six legged walking robot with 18 degrees of freedom is studied and built in this paper. the kinematic and gait analysis formulations are demonstrated by an e...

in this project guidance and control of underwater robot, including three engines and propeller attached to it, by fuzzy control has been investigated. fuzzy control is done based on human experience and requiered laws. the robot can also be controlled and guided by the user. this robot may be used in sea or swimming pool environment for finding goal point and locate in desired direction. in ad...
