in this research using the theory of induction motor (um), a um with liquid as secondary part is planned and manufactured. the main objective for planning of this motor is to investigate the possibility of chemical liquids pumping such as liquid poison and acids. results of many laboratory tests are shown to conclude that pumping force in the manufactured pump is dependent on many factors su...

Industrial robotics is a complex domain, not easily amenable to formalization using semantic technologies. It involves such disparate aspects of the real world as geometry, dynamics, constraint-satisfaction, planning and scheduling, real-time control, robot-robot and human-robot communication and, finally, intentions of the robot user. To represent so different kinds of knowledge is a challenge...

Abstract Walking is the basic way of human movement. How to model pedestrian in complex space a challenge. Various models such as social force and cellular automaton have been proposed. These can reproduce some macroscopic characteristics pedestrian, but are not very effective space. This paper proposes framework, including mental-planning-moving three layers. The mental layer depicts state ped...

We continue to advocate a methodology that we used earlier for pattern discovery through exhaustive search in selected small domains. This time we apply it to the problem of discovering state invariants in planning domains. State invariants are formulas that if true in a state, will be true in all successor states. In this paper, we consider the following four types of state invariants commonly...

Numerous studies have investigated the kinematics of arm movements; others have examined grip forces during static holding of objects. However, the coordination of grip force and arm movement when moving grasped objects has not been documented. We show that grip force is finely modulated in phase with load force during movements with grasped objects in which load force varies with acceleration....

Strategic planning is an essential part of establishing the Air Force’s direction. Using a group support system for strategic planning is one avenue to make effective use of technology and improve the strategic planning process. This research implements a group support system (GSS) as a facilitation tool to improve the strategic planning process at Mountain Home Air Force Base in Idaho with the...

This paper presents a new way for mobile robots’ path planning which is based on the Evolutionary Artificial Potential Fields(EAPF) approach. The APF theory is a traditional method to plan path for a robot. The Evolutionary APF aims at helping a robot jump out of the local minimum point. Using a virtual goal to produce extra force and fixing the direction of the repulsive force are combined to ...

In a number of industrial, space, or mobile systems applications, reaction forces and moments transmitted by a manipulator to its base are undesirable. Based on force and moment transmission analysis, a three DOF redundant manipulator design is selected aiming at reactionless motions. Dynamic reaction forces are eliminated by using force balancing. Reaction moments are eliminated by following r...
