LIST OF COMPONENETS

SL.NO COMPONENETS QUANTITY WEIGHT
1 Arduino mega 1 25g
2 Foam Board 1 350g
3 Wheels 4 250g
4 Storage container 1 100g
5 Water container 1 500g
6 Funnel 1 50g
7 Servo motor 5 75g
8 DC motor 4 360g
9 Acrylic parts 1 200g
Total Weight : 1910g

Force involved is just the downward force(weight of the design)

F=w*g(acceleration due to gravity=9.8m/s^2

F=1910*10^-3 * 9.8

F=18.718N

Radius=5cm

Torque=F*r

Torque=18.718*0.05

Torque=0.9359N-cm

so we use 4 dc motors of 60 RPM

BATTERY SIZING TOTAL RATING:

Voltage Rating Current Rating
12V 320mA

Applying the factor of safety FOS=1.2

Voltage Rating Current Rating
12V 384mA

Therefore for our course project we use 1 battery which is 12V

BATTERY :12V,0.5A
