For our course projec DC geared motor and 1 servo motor is required.

T= μ x M x g x D/2 η Here,

• μ= Coefficient of Friction

• T= Load Torque in N-m (convert it into kg-cm)

• D= Diameter of the pulley in m

• g= acceleration due to gravity

• η= Drive efficiency(assuming it as 0.9)

  P= 2 x π x N x T/60 Here,

• P= Power in watts/min

• N= Revolutions per minute(speed)

• T= Load Torque in kg-cm

Rated RPM at 12V	Rated Torque in Kg-cm at 12V
1000	0.12
500	0.25
300	0.35
200	0.5
150	0.8
100	1.2
60	2
30	4
15	8
10	12
3.5	30

We will use the motor of 60RPM

Sl.no	Components	Quantities	Operating voltage	Operating current of each component	Total current
01	DC geared motors	1	12V	300mA	300×1= 300mA
02	Arduino mega 2560	1	5V	100mA	100×1=100mA
03	LED lighting	1	3.6v	30mA	30x1=30mA
04	Servo motor	1	4.8V	650mA	650x1=650mA
05	Dual-Channel Relay Module	1	5V	70mA	70x1=70mA

12V	5V
300mA = 0.3A	850mA = .85A

We know factor of safety = 1.2

12V	5V
0.3×1.2= 0.36A	.85×1.2= 1.02A
