6.5 mechanism and resource specification

For course project 2DC geared motor is required

One for conveyor belt One for tilak applying machine Required R.P.M for DC motor of Tilak machine Torque= force × perpendicular distance (kg-cm)

Dimensions of 3cm link

Length 3cm

Height 2cm

Width 0.3cm

Volume=2.68

Dimensions of 18cm link

Length 18cm

Height 2cm

Width 0.3cm

Volume=11.46

Dimensions of 25cm link

Length 25cm

Height 2cm

Width 0.3cm

Volume=15.55

Dimensions of Tilak applier Volume=25.94

Calculations

Torque=force × perpendicular distance

Mass= distance × volume

Density of acrylic sheet is 1200

Total volume= 2.68+11.46×4+25.94 =89.73

Mass=1200×89.73 =0.107676kg

T= F × R = 0.107676×9800×0.27 =26.6~ (26r) =28 * 1.2 =31.2kg-cm ~ (30rpm)

Then the speed required motor is 30rpm

calculation for tilak moving system

Dimensions for belt system

Length=20cm, width=0.5mm, height=5cm

Volume of belt system=700cm^3

Dimensions for tilak container

Edge=2.5cm

Volume of Tilak container=15.62cm^3

Total volume=715.62cm^3

Density of acrylic sheet=0.00118kg/cm^3

Mass=density*volume

Mass=0.00118* 715.62

Mass=0.8444kg

Force=mass* acceleration due to gravity

Force=0.8334*9.8

Force=8.2757N

Torque=force* perpendicular distance *co-efficient factor

Torque=8.167* 0.2* 1.2

Torque= 1.9kg-cm (~2)

Then the speed of the required motor is 60rpm

BATTERY SIZING

Sl.no	Components	Quantities	Operating voltage	Operating current of each component	Total current
01	DC geared motors	2	12V	300mA	300×2= 600mA
02	Arduino mega 2560	1	5V	100mA	100x1=100mA
03	LED lighting	3	3.6v	30mA	30x3=90mA
04	IR sensor	2	3.3v	20mA	20x2=40mA

12V	5V
600mA = 0.6A	230mA = 0.23A

Factor of safety = 2
