With the recent technological advancement in submersible systems, the research and development of underwater manipulator robot is highly desirable. This paper focuses on comparing simulation versus real-time manipulator dynamics control, and comparison of intelligent underwater manipulator-robot for effective Ocean-based research, industrial and defense applications. Software package such as MA...

This paper presents a novel robust fractional PIλ controller design for flexible joint electrically driven robots. Because of using voltage control strategy, the proposed approach is free of problems arising from torque control strategy in the design and implementation. In fact, the motor's current includes the effects of nonlinearities and coupling in the robot manipulator. Therefore, cancella...

Conventional methods for programming a robot either are inflexible or demand significant expertise. While the notion of automatic programming by high-level goal specification addresses these issues, the overwhelming complexity of planning manipulator grasps and paths remains a formidable obstacle to practical implementation. Our approach of programming a robot is by direct human demonstration. ...

In this paper we describe mechanical and electronic design of a precision, 2-DOF robot manipulator. The manipulator is one of a wide variety of modular robotic agents in the minifactory, a rapidly depoyable precision assembly system under development in our laboratory. The manipulator, in cooperation with another type of 2-DOF robot, termed a courier, can perform 4-DOF assembly operations emula...

the main objective of this paper is to introduce a new intelligent optimization technique that uses a predictioncorrectionstrategy supported by a recurrent neural network for finding a near optimal solution of a givenobjective function. recently there have been attempts for using artificial neural networks (anns) in optimizationproblems and some types of anns such as hopfield network and boltzm...

This paper describes the integration of robot path-planning and spatial task modeling into a software system that teaches the operation of a robot manipulator deployed on International Space Station (ISS). The system addresses the complexity of the manipulator, the limited direct view of the ISS exterior, and the unpredictability of lighting conditions in the workspace. Robot path planning is u...

This paper introduces a new approach to control a robot manipulator in a way that is safe for humans in the robots workspace. Conceptually the robot is viewed as a tool with limited autonomy. The limited perception capabilities of automatic systems prohibits the construction of failsafe robots of the capability of people Instead, the goal of our control paradigm is to make the interaction with ...

A power assisted gait rehabilitation robot system by which a patient who has difficulty in walking can exercise is proposed. Our developed system consists of a robotic manipulator which can adjust the height of the system according to the user and a mobile base with two-driving wheels. It is similar to the architecture of a mobile manipulator. The neural network based control algorithm for a mo...

This paper deals with the implementation of a hybrid force/velocity controller for the contour tracking of an object of an unknown shape performed by an industrial robot manipulator. In particular we propose the use of a gain scheduling approach in order to cope with the configuration dependent dynamics of the manipulator in constrained motion and therefore in order to allow to obtain satisfact...

The probabilistic modelling of a robot manipulator workspace when combined with a Human-Machine Interface (HMI) allows the extraction and learning of the spatial preferences of the user. Furthermore, the knowledge of the most accessed zones of the robot’s workspace permits the bounding of the time needed for the robot to reach a given position at its workspace. From its early beginning, the use...
