Motor sizing and Battery sizing of Subsystem 1- Robotic arm and handling unit
MOTOR SIZING
Details of Arm:
Dimension :15x3x0.5 cm
Material :Acrylic Sheet
Density of Material:1.185 g/cm3
Mass =37.5 x 1.185 =44.4375 g
MASS OF MARACAS =150 GM TORQUE REQUIRED:
Diameter of shaft required = 8cm=3.146inch
Total Mass: 200gm
Torque = mass * diameter of shaft / 2
Torque = 0.2 * 8/2 = 0.8 kg-cm
FOS = 1.2 TorqueFOS = 0.81.2 = 0.96 kg-cm
SERVO MODEL: TOWER PRO SG 90
BATTERY SIZING
Components Used :
- Arduino Mega 2550: 5V – 12V/100mA
Factor of Safety : 1.2
With F.O.S 5v/120mA
TOWER PRO SG 90 Servo Motor : 5V /650mA
Factor of Safety =1.5
with F.O.S 5V /975mA
TOTAL : 5V/1095mA
REQUIREMENT 12V 2A ADAPTER
