The optimal kinematic design of robots is an interesting problem in contemporary robotics. It is important to have measures for determining the precision of the mechanism and size of the robot manipulator at the design phase. This all has been done before mostly on the basis of experience. The most essential issue for setting up any measures seems to be the ease of changing arbitrarily the posi...

In this paper, a kinematically redundant parallel haptic device with large workspace is presented. The haptic device has a similar kinematic structure to the well‐ known Delta manipulator. However, it has a special arrangement of actuators and one redundant actuator added to the third leg. The proposed haptic device has essentially 4‐DOF, however, only three tra...

the aim of this study was to design the strategic orientations model of market, brand and entrepreneurship in the food industry in iran.  the organizational decisions are not formed  in a vacuum but in the economic and cultural environmental context of each country, they are much influenced by many different factors. this study is of applied type and was conducted in two stages. first after an ...

In this paper the workspace optimization of translational 3-UPU parallel platforms with prismatic and universal joint constraints is performed. The workspace is parameterized using two design parameters, which are the prismatic joint stroke and the difference between the distances of the center to one of the corners of the triangular plate of the base and of the moving platform. For a large ran...

today, market orientation plays a vital role in determining customers’ needs and success of organizations. market orientation has also influenced various organizations’ measures including innovation. therefore the aim of this research is to study the role of market orientation in innovation of bodybuilding clubs of golestan province. the population of this study comprised all 170 managers of bo...

Visual servoing methods are reviewed along with their limitations in low-cost uncalibrated situations. A description of the camera model is then given including an overview of visual Jacobian calculations. The problem of selecting suitable gains for implementation in real-time is developed. The model system used is of the anthropomorphic service robot HERMES. It is highly non-linear and redunda...

In this paper a waist rehabilitation robot driven by cables and pneumatic artificial muscles (PAMs) has been conceptualized and designed. In the process of mechanism design, the human body structure, the waist movement characteristics, and the actuators' driving characteristics are the main considerable factors to make the hybrid-driven waist rehabilitation robot (HWRR) cost-effective, safe, fl...

Abstract: This paper introduces a cable-suspended robot, the Vehicle Simulation System, designed for pilot and driver training. The main idea of this work is to make a system that will provide realistic simulations of vehicle motion using virtual reality and a motion platform. A method to produce inertial forces acting on the vehicle user is proposed. A detailed description of the robot’s dynam...
