INTRODUCTION TO FLUID POWER

Fluid power is a term which was created to

include the generation, control, and application

of smooth, effective power of pumped or

compressed fluids (either liquids or gases) when

this power is used to provide force and motion to

mechanisms. This force and motion maybe in

the form of pushing, pulling, rotating, regulating,

or driving. Fluid power includes hydraulics,

which involves liquids, and pneumatics, which

involves gases.

INTRODUCTION

An industrial robot is officially defined by ISO as

an automatically controlled, reprogrammable,

multipurpose manipulator programmable in three

or more axes.

The Robotic Manipulator Arm extends the

flexibility of workstations by transporting materialmore efficiently and quickly between worktable,

peripheral devices and assembly lines etc.

Despite its numerous possible usages, it finds

most widespread usage in manufacturing

industry. Typical applications of robots include welding,

painting, assembly, pick and place, packaging and

palletizing, product inspection, and testing, all

accomplished with high endurance, speed, and

precision.

ADVANTAGES OF FLUID POWER

They eliminate the need for complicated systemsof gears, cams, and levers.

The fluids used are not subject to breakage or

wear as are mechanical parts.

The forces can be conveyed up and down or

around corners with small loss in efficiency and

without complicated mechanisms. Very large forces can be controlled by much

smaller ones and can be transmitted through

comparatively small lines and orifices

It can provide smooth, flexible, uniform action

without vibration, and is unaffected by variation

of load. In case of an overload, an automaticrelease of pressure can be guaranteed

Fluid power systems can provide widely variable

motions in both rotary and straight-line trans-

mission of power.

CONCEPT

The basic concept used behind the operation isPASCALs LAW. This law states that when a pressure is

applied at one point of a fluid contained in a constrained

volume, then the pressure due to that force is equally

transmitted to all the points of the fluid, which are acted

upon by the same pressure.

Using the same principle, we applied pressure to fluid insyringe which is transmitted to other end of tube which

is connected to a syringe. This motion of the syringe is

used to move the links or parts of the mechanism which

are attached to respective syringes.

PASCALS LAW

The foundation of modern hydraulics

was established when Pascal

discovered that pressure in a fluid acts

equally in all directions. This pressure

acts at right angles to the containing

surfaces. If some type of pressure

gauge, with an exposed face, is placed

beneath the surface of a liquid at a

specific depth and pointed in different

directions, the pressure will read the

same. Thus, we can say that pressure

in a liquid is independent of direction.

Pressure due to the weight of a liquid,

at any level, depends on the depth of

the fluid from the surface.

WORKING

A robotic arm which is hydraulically

operated and controlled by syringes filled

with some fluid. It consists of various parts

connected to each other in a pre-designed

manner which are guided in a constrained

way to obtain required output.

APPLICATION

The Hydraulic Arm will

Deliver the most objects in a given amount

of time.

Function in an assembly line. Have a system to weigh the object it picks

up.

Rotate as well as reach and grab.

Dig and recover objects

conclusion

Our design uses extremely simple ideas andmechanisms to achieve a complex set of

actions and is intended to imitate the

actions of the operators. However, these

hydraulic arms are expensive for small

scale industries. If the major problem of

high initial cost is addressed, a robotichydraulic arm can be introduced in any

industry to bring in automation. The

mechanical links and parts that have been

fabricated are extremely simple.
