SYNOPSIS
This project focuses on the principles of hydraulic movements.A hydraulic arm is a
simple machine that uses the transfer of pressure through an enclosed static liquid
medium to lift an object. In accordance with Pascal's principle, the pressure is
transmitted from one end of the hydraulic arm to the other undiminished. When the area
of the piston that receives the pressure is larger than that of the initial piston, the
upward force exerted by the second piston is several times stronger than the downward
force exerted on the first piston. The arm is controlled by syringes filled with some fluid.

ACKNOWLEDGEMENT
We student from SJK(T) Perai, are preparing a science fair project name ‘ Hydraulic
Caterpillar’. We would like to express our sincere gratitude to Mrs Gayathree who
guided us through out this project. We are also thankful to all the science teachers for
explaining on critical aspect of topic related to the project. We would like to thank Mr
Arvind also, who help us to complete the project. We also would like to thank our
headmistres Mrs Tamil Selvi who give us chance to take part in this competition. We
dont want to miss our PIBG, who have sponser our project.

INTRODUCTION
Hydraulic Arm is a system which coupled by machines and hydraulic. It is widely
applicable in all kinds of large engineering equipments such as crane. In hydraulic arm,
the dynamic differential equation is built with the driving force of the hydraulic cylinder
as the main force. A robotic arm which is hydraulically operated and controlled by
syringes filled with some fluid. The hydraulic supply act like the arm’s heart and muscle.
It provides the energy for pushing, pulling, turning and lifting.
In this project hydraulic power is used as the main component. Hydraulic power, also
called Fluid Power, power transmitted by the controlled circulation of pressurized fluid,
usually a water-soluble oil or water–glycol mixture, to a motor that converts it into a
mechanical output capable of doing work on a load. Hydraulic power systems have
greater flexibility than mechanical and electrical systems and can produce more power
than such systems of equal size. They also provide rapid and accurate responses to
controls. As a result, hydraulic power systems are extensively used in modern aircraft,
automobiles, heavy industrial machinery, and many kinds of machine tools.
In our innovation, we use hydraulic power to move an object from one place to another
place. We can use this project to save energy and control pollution.

TOOLS / MATERIALS
pieces of wood
Electric drill
Screws
Screwdriver
Washers
Nuts
two plastic 50-mL syringes
3 plastic 20ml syringes
clear plastic tubing that fit the syringe tips
Scissors
Water
small objects.
SAFETY PRECAUTION
Wear safety glasses
When pressing on the syringe, be sure to press only the input part with your
thumband, hold the output syringe with other hand to prevent the syringe from
separate

EXPERIMENTAL PROCEDURE
1. Two pieces of wood is cut into few pieces.
2. The pieces of plywood is joined using screw and washer.
3. The pieces of plywood is fixed to a arm shape.
4. The arm shape plywood is fixed on the cardboard base.
5. 20ml of syringe is fixed on three parts of arm. Place the cable tie near the bottom
of the fixed syringe. Pull the cable tie as tight as possible so the syringe does not
easily slip.
6. 2 syringe of 50ml is used to move the arm right to left.
7. Fill the syringe and tube completely with water. (If there are air bubbles, try
flicking the syringe or tube with your finger to get them to rise, and then top off
with more water as necessary. If you have difficulty, try detaching the hose and
filling it separately, and then reattaching it to the full syringe.)
8. Push the plunger all the way into the fixed syringe so that there’s no air in the
syringe. Attach the open end of the water-filled tube firmly to the tip of this
syringe. Be sure there are no large air bubbles anywhere in the system.

RESULT/OBSERVATION
The object is carried by the arm using syringe when the plunger is pushed .
DISCUSSION
Pushing on the plunger applies pressure on the water in the movable syringe. Since the
water is confined and incompressible, Pascal’s principle comes into play, telling us that
the pressure is transmitted undiminished to all parts of the water and to the walls of its
container. Since the plunger of the fixed syringe at the other end of the tube forms part
of the “container” for the water, and is the only part of the container that can expand, the
pressure causes the plunger in the fixed syringe to move.

CONCLUSION
Our innovation can make the work easier especially in a industrial area. Hydraulic arm
can be used in a production and packaging field. The innovation is very easy to repair
and the design also very cheap. The project also only need a small area to set up. It is
easy to control . The important fact about the project is it is using renewable energy.
