--- SELECTION AND DESCEPTION OF PROJECT ---

First of all, we think over many project like Solar Water Heater, Screw

Jack, Boom Lifter , Robotic Arm By Hydraulic Control then after we are selected the

PICK AND PLACE ROBOTIC ARM BY PNEUMATIC CONTROL.

In the choice of location for PICK AND PLACE ROBOTIC ARM BY

PNEUMATIC CONTROL, Several Component may be involved like compressor, electric

low rpm motor, rack and pinion, pneumatic piston and cylinder and many others. There

is no easy answer to the question rose, which is suitable site for PICK AND PLACE

ROBOTIC ARM BY PNUMETIC CONTROL? The only solution is to study several

alternatives layouts and adopt one which appears to be most economical.

Some time the most desirable location is apparent to an experienced

engineer. Sometimes there is no choice for site expect considerable investigation and

study are required to determine the most economically location.

The purpose of preliminary investigation is to provide sufficient information

to find out the practicability of the proposed scheme and to choose between alternations

can be prepared and recommendation is made reasonable confidence.



--- WORKING OF PROJECT ---

This project has sample work. Its work is to pick object or work-piece at

one site and to place that object or work-piece another site.

In figure showing PICK AND PLACE ROBOTIC ARM BY PNEUMATIC

CONTROL. Its working steps as under below:

1. Compressed air comes from the compressor.

2. By using air controlling manual valve air comes in cylinder which is located

between column and arm and arm rise up by presser of cylinder’s piston.

3. By using low RPM motor column rotate to object.



4. By losing air in cylinder which one placed in arm opens jaws by using rack

and pinion mechanism.

5. Arm become down to object by losing air in cylinder.

6. Object comes between two jaws.

7. By increasing presser in cylinder jaws close and object pick in jaws.

8. Arm rise up by column’s cylinder.

--- MAKE OR BUY DECISION OF PROJECT ---

Material, labour and other expenses plus different types of overhead

expenses are incurred for manufacturing the product. For manufacturing the product

workshop machinery, tools, instruments and other facilities are used. To create such

facilities industry has to provide investment. It is necessary to produce good quality of

products in sufficient quantity, by providing close supervision to the production activities.

The services or use of instruments, laboratory equipments and inspectors for quality

control work also demands investment and expenses. When different types of facilities

and services are required for producing different parts of a product to be manufactured.

Then capital investment and no. of manpower required in an industry are increases.

This gives rise to the overhead cost which in turn results into increased cost of

production but produced product if available in market its price is lower or same as our

product, we have to go for buy that product in place of producing it. The different

advantages of purchasing readymade parts are as follows:

►No responsibility of rejection of part.

►Capital investment reduces.

►No problem of wastage of materials.

►No. of workers & labour problem are reduces.

►Parts of required quality can be obtained.

►Timely purchasing of parts can be done.

► It becomes easy to meet the production target.

--- DETAILS OF INSPECTION / TESTING OF PROJECT ---

After making all component of project we inspection all component and its specification or parameters as per drawing. We assemble all component make assembly of project. To test this project working we connected project with air compressor by use of pneumatic connecter. When we started air compressor, we just become so eager to see our project working. We opened air compressor valves and air comes in pipe. By manual pneumatic valve air comes in cylinder and our project works successfully but there is one problem that is cylinders works so fast and powerful so by using silence in manual valves we reduces pressure of air.

Doing above works our project works smoothly. It can pick bottles, brick and box which weight is not greater than 4 kilograms because in this project we use low RPM motor to give rotation motion project. It is capacity 7 kilograms to take load and project assembly weight 3 kilograms.

To test and inspect our project we find our hard works in great satisfaction and we are so happy to see working of project.
