In this paper, we present a vision guided robotic ball-beam balancing control system, consisting of a robot manipulator (actuator), a ball-beam system (plant) and a machine vision system (feedback). The machine vision system feedbacks real-time beam angle and ball position data at a speed of 50 frames per second.

In this paper a survey of the literature related to dynamic analyses of flexible robotic manipulators has been carried out. Both link and joint flexibility are considered in this work and an effort has been made to critically examine the methods used in these analyses, their advantages and shortcomings and possible extension of these methods to be applied to a general class of Cited by: In this paper, we present a vision guided robotic ball-beam balancing control system, consisting of a robot manipulator (actuator), a ball-beam system (plant) and a machine vision system (feedback).

In both cases, the former can be used for vibration suppression and the latter for input tracking of a flexible manipulator. A combination of the control techniques would practically position the end-point of the flexible manipulator from one point to another with reduced vibration.

Both feedforward and feedback control structures have been utilized in the control of flexible manipulator systems. This paper presents the results of hybrid vibration controllers applied for vibration suppression of flexible manipulator.

The model of the manipulator is assumed to be uncertain due to varying payload. To cater for the model uncertainty the proposed hybrid controller combines robust input shaping for command input with μ-controller applied for active vibration suppression using Author: Muhammad Atif Khushnood, Xiaogang Wang, Naigang Cui.

derived the recursive dynamic equations for a flexible manipulator. However, the recursive method must be evaluated symbolically to obtain the dynamic equations in closed form. Finally, Book [8] reviews the mathematical representations commonly used in modeling flexible systems.

Hastings and Book [17] extended active control methods by. This paper is concerned with vibration control of a single-link flexible beam structure. The proposed beam is controlled by a servo motor through a harmonic gear reducer.

After obtaining the models by system identification, a time-delayed optimal controller based on model output prediction and optimal control theory was designed to compensate.

The positioning accuracy and work efficiency of flexible manipulator is seriously affected by its vibration. Therefore, vibration control of single joint flexible manipulator is studied by using an improved PPF algorithm based on LabVIEW and piezoelectric technology.

Firstly, the improved PPF algorithm principle is introduced. Then, the experiment process is discussed in : Fei Du, Tian Bing Ma. The manipulations can be made by only one manipulator on a working table and with machine vision feedback. The main goal of this method is to detect, evaluate and classify the regions of interest (ROIs) which, in the particular case, are the corners of the fabric lying on the by: 8.

for general purpose implementation. Then, the dynamic model in the absolute coor-dinates system is converted into independent coordinates form using a recursive kine-matic formulation. The advantage of general purpose algorithm is it uses minimum set of equations that define the dynamics of flexible manipulator, which is required in con.

A manipulator with multiple flexible links is a multivariable system of considerable complexity due to the inter-link coupling effects that are present in both rigid and flexible motions.

Example 1: 3-DOF Planar Manipulator A planar manipulator with 3 degrees of freedom is constructed with three revolute joints. A reference coordinate system is attached to the base such that the manipulator moves in this system's x-y plane.

For this manipulator, all the twist angles and offset distances of the links are equal to Size: KB. The best control strategy for controlling the tip position of flexible single link robotic manipulator is obtained by implementation of LQR controller.

Finally, it is concluded from our study that LQR control method is the best method among PID and State feedback controller to control the flexible link manipulators. Machine Vision Solutions for Industries Every industry relies on innovative technologies to help improve overall performance and productivity.

Machine vision technologies minimise waste and manual labour whilst increasing yields, a solution that would benefit any company. Compared to conventional rigid robotic manipulators and unlike traditional industrial robotic manipulators, flexible manipulator can be more efficient and safer to operate due to their low power consumption and lightness.

Moreover, the next generation of robots will require compliance to be able to perform safe and close interactions with human : Xi Luo.
