4. ABSTRACT
 The Robotic Manipulator Arm extends the
flexibility of workstations by transporting
material more efficiently and quickly between
worktable, peripheral devices and assembly lines
etc. A sub class of more general family of Robots,
the Industrial Robots. An industrial robot is
officially defined by ISO as an automatically
controlled, reprogrammable, multipurpose
manipulator programmable in three or more
axes. Despite its numerous possible usages, it
finds most widespread usage in manufacturing
industry.

5. AIM OF THE PROJECT
 The main aim of our project is to build a hydraulic arm
that can grip or pick thinks.
 We have implemented the hydraulic arm that can be
controlled by gesture commands.
 We have proposed a simple algorithm for hand
controlling.

6. HYDRAULIC SYSTEM
 A hydraulic drive system is a drive or transmission system
that uses pressurized hydraulic fluid to power hydraulic
machinery. The term hydrostatic refers to the transfer of
energy from flow and pressure, not from the kinetic energy
of the flow.
 A hydraulic drive system consists of three parts: The
generator (e.g. a hydraulic pump), driven by an electric
motor, a combustion engine or a windmill; valves, filters,
piping etc. (to guide and control the system); and the
actuator (e.g. a hydraulic motor or hydraulic cylinder) to
drive the machinery

7. PRINCIPLE
 Pascal’s law the basis of hydraulic drive systems. As the pressure in the
system is the same, the force that the fluid gives to the surroundings is
therefore equal to pressure area. In such a way, a small piston feels a
small force and a large piston feels a large force.
 A change in pressure at any point in an enclosed fluid at rest is
transmitted undiminished to all points in the fluid

8. APPLICATIONS
 The underlying principle of the hydraulic jack and
hydraulic press
 Force amplification in the braking system of most
motor vehicles.
 Used in artesian wells, water towers, and dams.

9. OUR MODEL PROJECT

10. REQUIREMENTS
 MS PLATE
 SYRINGES
 BALL BEARINGS
 TUBES
 BOLT AND NUTS
 FLUID
 CLAMPS

11. ROBOT POWER The power for a robotic arm can
either be electric, hydraulic, or
pneumatic.
 Hydraulics is putting liquids
under pressure
 Pneumatics is putting gases under
pressure.
 The power supply acts like the
robot's heart and muscles. It
provides the energy for pushing,
pulling, turning and lifting.

13. APPLICATIONS
 The hydraulic arm that can grip or pick thinks in
industrial purpose.
 These arms are used in assembly lines of mega
factories to assemble the various parts of product and
also to paint vehicles.
 They are also used in earth movers to pick up heavy
weight and keep them where required.
 Same principle is being used in JCB’s , automobiles,
lifters.

14. SAFETY PRECAUTIONS When pressing on the syringe
system, be sure to press only the
input plunger with your thumb and
hold the output syringe with your
other hand to prevent the syringe
from separation.
 Do not use syringe as a “squirt gun”.
 Wear safety glasses.
 Follow all normal laboratory rules.

15. ADVANTAGES
 The robot used can have many industrial uses.
 When used in locomotive format can be of great use in
the production and packing field.
 The simplicity and easy to repair design makes it really
cheap.
 Cost is low.
 Easy to design.

16. FUTURE SCOPE
 If more time and more efforts would have been put
into the model, more complexity could have been
brought out.
 Moreover instead of manual operation of syringes
could have been replaced by pre-defined computer
program or merely by pressing switch operated.
 Further more varieties and more flexibility to add or
replace any part according to the requirements can be
done to improve its use and increase field of usage and
to make it more universal or flexible

17. CONCLUSION
 The prepared mechanism has been successfully
constrained and executed to carry out the required
work of picking up the weight of the object like table
tennis ball and to put them in to the placed at different
location.
