The five-bar manipulative system has the advantages of high and even the bar of fives. These techniques are also synthesis applied to biological systems efficiency, high payload and application flexibility. This Figure 4: Representation of MS with Two Open in the linkage decade, the servo motors are now problems and also the velocity V of that point B reached by the first and requires the solution operations same, we obtain the system, kinematics ; ; or. It was driven by two proteins posses a resolution of 0.

The second set of analysis is the relation between the velocity of end-effector to speed of the individual link servos. The velocity control is obtained by simplifying the jacobian matrix of the angular velocities of the driving links. These angular velocities can be converted into individual speeds of the servos which act as the real time input. This kind of effective velocity control is suitable of path following end- Figure 2: Schematic Diagram of Five-Bar Manipulative effector industrial needs.

The bodies 1 and 4 are the driving bodies. With the help of the appropriate rotation of the I. The five link follow the desired planar trajectory in the borders of the working zone. This paper assumes that the lengths of the links are l1, l2, l3, planar manipulative system MS , shown in Figure 1, contains l4, and l5, the angle between the links are. The only rotational joints[1]. The five-bar manipulative system has the advantages of high efficiency, high payload and application flexibility.

Five- bar MS can be found in many industrial applications as positing devices which improve the positional resolution, stiffness and force control of the manipulators. Initial position of the links can be obtained by the kinematic analysis of MS. E-mail:louisvathan gmail. E-mail:hoshilamech gmail. E-mail:engineer yahoo. Equations 3 and 4 gives an indirect way to determine The Figure 3 shows the placement of the above mentioned the actuating angles in the manipulative system for a particular link angles in the five-bar manipulative system.

For effective control some modifications are made over the pre-existing equations. These modified equations give the direct relation between the coordinates of the end-effector and link lengths to the actuating angles.

By combining the equations 1 and 2 and eliminating the secondary angles and the following equations are obtained. Usually the transfer function is described by the Jacoby matrix J.

This expression is known as forward kinematics problem The equations 5 and 6 give a direct control over the and for the considered MS could be solved by using different actuating angles without knowing the dependent approaches. The analytic symbolic solution could be angles. Since the links lengths are constant for a particularly useful for making several conclusions concerning predefined robot the above equations can be simplified indeed.

Then the coordinates of the end-effector is the [2] only inputs required for controlling the mechanism. This Figure 4: Representation of MS with Two Open Structures The classical approach for solving such kind of problems and also the velocity V of that point B reached by the first and requires the solution of standard position task forward second MS is the same, we obtain the system, kinematics ; ; or of the inverse kinematics.

After the obtained results are differentiated with respect to the general coordinates. The forward kinematics standard position task has two solutions, the inverse-four. These arguments determine the necessity to search for other approaches for the analytical solution of the forward or in matrix form: kinematics position task. The matrix of Jacoby J1,2 for each of them is known. For Eliminating the angular velocities in the passive the left J1 MS we obtain, joints for the forward kinematics problem it is obtained that, where: or in a matrix form, where, Analogously we can obtain for the right system: where, [2] The above equations 8 , 9 , 10 , 11 and 12 , gives way to find the angular velocity of joints A, B, C and D and the linear velocity of the end-effector C.

But these are If it is admitted that the distance between both systems is l1, and that they reach one and the same point B, complex which requires more resources to solve and find the the robot workspace requirements, the paths traced by the end- active links angular velocities. Here the inputs are assumed to be the velocity required at the end-effector, and the constants which values are given above.

The velocity of the end-effector is differentiated into an x and y components based on the direction of movement.

These components are needed to be found out before applying in the equations 13 and The speed of the individual motors 1 and 4 controlling the links A and B can be found out easily using the following Figure 5: Featured Automated Drilling Machine using relations: Five-Bar MS The Figure 5 shows a CREO modeled automated robot which can make drills in any of the indicated coordinates based on the requirements.

Some of the applications of five-bar mechanism in robotics For path movements of the end-effector the speed and are listed below.

In high speed, high-accuracy positioning with limited From these modified equations the real time variable speed workspace, such as in assembly of PCBs. As commercial pick and place robot. There is a need to provide a robotic system which is useful For generating walking gait in biped robots and in automation and achieves a reasonable measure of flexibility swimming gait in swimming robots.

The term "flexibility" refers to the ability of a robotic system to be deployable to perform a In automatic planar measuring devices. In this context, the term "task" refers to a Many of these robotic applications need a path to be mechanized motion in one, two, or three dimensional space generated by the end-effector for operation. For this the along a prescribed path. Serial industrial robots are widely employed in automated Trajectory Control of a Welding Robot: manufacturing operations, such as in the assembly of mechanical and electronic components, welding, painting, It is assumed that an automated welding to be made sealing, etc..

As a force rotates the lever, points far from the fulcrum have a greater velocity than points near the fulcrum. Because power into the lever equals the power out, a small force applied at a point far from the fulcrum with greater velocity equals a larger force applied at a point near the fulcrum with less velocity. The amount the force is amplified is called mechanical advantage. This is the law of the lever. Two levers connected by a rod so that a force applied to one is transmitted to the second is known as a four-bar linkage.

The levers are called cranks , and the fulcrums are called pivots. The connecting rod is also called the coupler. The fourth bar in this assembly is the ground, or frame, on which the cranks are mounted. Linkages are important components of machines and tools.

Examples range from the four-bar linkage used to amplify force in a bolt cutter or to provide independent suspension in an automobile, to complex linkage systems in robotic arms and walking machines. The internal combustion engine uses a slider-crank four-bar linkage formed from its piston , connecting rod , and crankshaft to transform power from expanding burning gases into rotary power.

Relatively simple linkages are often used to perform complicated tasks. Interesting examples of linkages include the windshield wiper , the bicycle suspension , the leg mechanism in a walking machine and hydraulic actuators for heavy equipment. In these examples the components in the linkage move in parallel planes and are called planar linkages. A linkage with at least one link that moves in three-dimensional space is called a spatial linkage.

The skeletons of robotic systems are examples of spatial linkages. The geometric design of these systems relies on modern computer aided design software. History[ edit ] Archimedes [3] applied geometry to the study of the lever. Into the s the work of Archimedes and Hero of Alexandria were the primary sources of machine theory.

It was Leonardo da Vinci who brought an inventive energy to machines and mechanism. This drove his search for a linkage that could transform rotation of a crank into a linear slide, and resulted in his discovery of what is called Watt's linkage.

In these examples the components in the linkage move in parallel planes and are called planar linkages. As commercial pick and place robot. E- Mail: engineer yahoo. These angular velocities can be converted into individual speeds of the servos which act as the real time input. The bodies 1 and 4 are the driving bodies. The analytic symbolic solution could be angles.
