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.

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.

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

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

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.

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.

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.

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.

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.

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

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.
