POST POLISHING

Building phase

Building phase of sprint 3 involves post polishing.Where an airblower is fixed to clean the compartment dirt which gets deposited after completing the prepolishing and polishing phases.A 12V air blower is used for this purpose.We are using Bluetooth module to carry out this task and a LED bulb is used to indicate the completion of entire process.

Fabrication plan

SL no	Part	Off-the shelf part	custom-made or hand crafted part	Type of Material	Fabrication process if needed	Approximate time needed for fabrication
1.	Air blower	Yes	---	plastic body	fixing in the compartment	20 mins
2.	LED light	yes	--	Metal and glass	fixing on the clamp	10 mins
3.	Dust collecting tray	--	hand made	metal sheet	bending and shaping	25 mins

Program

void setup

Serial.begin(9600);

pinmode(9,OUTPUT);

pinmode(10,OUTPUT);

pinmode(11,OUTPUT)

}

{

int data==Serial.read()

if (data==3)

{

difgitalwrite(9,HIGH);

Interaction phase

	sub system 03
	sub system 01	sub system 02
Energy interaction	No	No
Data interaction	No	No
Material interaction	Yes	No
Spatial interaction	Yes	No

Explanation:Sub system 03:

There exists material interaction between sub system 03 and 01 since shoe is a material here,there also exists spatial interaction since the dimensions of the shoe is required.After the completion of work the machine has to indicate the completion of work hence there exists data interaction between sub system 03 and 02.
