چکیده

This paper describes solutions that can be applied to pneumatic manipulator problems in positioning, both for angle trajectories and for long linear trajectories, used in construction tasks. Optimal positioning of a pneumatic manipulator along angle trajectories with minimum control energy consumption is given. The implementation of the control system is presented. Control algorithms for a long linear trajectory manipulator based on two-phase and three-phase motion modes of the endeffector are investigated. Conventional and fuzzy logic controls of a pneumatic manipulator were applied and experimental testing was carried out. The obtained results allow widening the application range of pneumatic manipulators in construction, particularly in gantry type machines. D 2002 Elsevier Science B.V. All rights reserved.

Optimal discrete-time control of robot manipulators in repetitive tasks

Optimal discrete-time control of linear systems has been presented already. There are some difficulties to design an optimal discrete-time control of robot manipulator since the robot manipulator is highly nonlinear and uncertain. This paper presents a novel robust optimal discrete-time control of electrically driven robot manipulators for performing repetitive tasks. The robot performs repetit...

Fuzzy logic positioning system of electro-pneumatic servo-drive

Development of automation and robotization in manufacturing process stimulates interest in pneumatic servo-systems whose advantages include low manufacturing costs, high dynamics and reliability (Situm et al., 2004). Unsatisfactory positioning accuracy of multiaxis pneumatic servosytems considerably reduces their application in manipulating machines, manipulators and robots. Rapid advance in pa...

Control of Wheeled Mobile Manipulators with Flexible Suspension Considering Wheels Slip Effects

Wheeled mobile manipulators utilize both the locomotion capabilities of the wheeled platform and manipulation capacity of the arm. While the modelling and control of such systems have previously been studied, most of them have considered robots with rigid suspension and their wheels are subject to pure rolling conditions. To relax the aforementioned limiting assumptions, this research addresses...

A survey of non-prehensile pneumatic manipulation surfaces: principles, models and control

Many manipulation systems using air flow have been proposed for object handling in a non-prehensile way and without solid-to-solid contact. Potential applications include high-speed transport of fragile and clean products and high-resolution positioning of wafers. This paper discusses a comprehensive survey of state-of-the art pneumatic manipulation from the macro scale to the micro scale. The ...

An Adaptive-Robust Control Approach for Trajectory Tracking of two 5 DOF Cooperating Robot Manipulators Moving a Rigid Payload

In this paper, a dual system consisting of two 5 DOF (RRRRR) robot manipulators is considered as a cooperative robotic system used to manipulate a rigid payload on a desired trajectory between two desired initial and end positions/orientations. The forward and inverse kinematic problems are first solved for the dual arm system. Then, dynamics of the system and the relations between forces/momen...
