7. Motor Sizing and Battery Sizing - D-Division-2021-22-ODD/Repo-09 GitHub Wiki
Battery sizing
| SI NO | COMPONENT | QUANTITY | VOLTAGE |
|---|---|---|---|
| 1 | Ultrasound sensor | 1 | 5v |
| 2 | DC motor | 1 | 12v |
| 3 | Serrvo motor | 2 | 5v |
| 4 | Buzzer | 1 | 5v |
| 5 | LED | 3 | 3v |
Required voltage and current supplies
- 12V 300mA supply considering the factor of safety as 1.2
final power= 12V 360mA
- 5V 1380mA supply considering the factor of safety as 1.2
Final power= 5V 1.6565A
Therefore we are going to use a 12V 2A adapter along with the power regulator of 12V to 5V
Motor sizing
Our design is about 4000g made up of foam sheet
1)Vertical force involved (Weight of the body consisting of plucking subsystem):
- W=150 g
- F=Wg (acceleration due to gravity(g)=9.8m/s^2) F=15010^-39.8 *F=1.47
2) Radius=10cm:
Torque=Fr
Torque=1.4710cm*0.001kg
*Torque=0.0147kg-cm
3)Radius(length)=35 cm (Movement subsystem):
Torque=Fr
Torque=3500.001kg*35cm
*Torque=12.25kg-cm
