Phase2:Conceptual design
List of identified functions
- Read the bar code of medicine
- Recognize the rack
- Sense the medicine
- Pick the medicine
- Display the cost of medicine
2.1 Use case diagrams
2.1 List the associated with each of the functions as indicated in the use case diagram
| Function1 |
|---|
| 1. Receives the data |
| 2. Moves to the respective rack |
| 3. Pick the medicine |
| Function2 |
|---|
| 1. Read the bar code |
| 2. verify weather right or wrong medicine |
| 3. verify the cost |
| Function3 |
|---|
| 1. Display the cost |
2.2 List the inputs ,outputs of the system and represents black box model
| Inputs | Outputs |
|---|---|
| 1.Electricity | 1.Fectching Medicine |
| 2.Data | 2.Display the cost |
2.3 Write the glass box representation of the system in terms of functional blocks (represent the material,energy and the data interactions with different colours)
| Function 1 |
|---|
| The device has to accept the input barcode and analyse the medicine using the sensor.Read the barcode and choose correct medicine amongst all |
| Function 2 |
|---|
| After choosing the correct medicine pick the medicine from the rack using robotic arm and place it on the collection place provided |
| Function 3 |
|---|
| Then the device with the help of wheels moves on the track towards the billing section |
Task 2.4:Complete the morphological chart by exploring the others alternative means of achieving the functions
| Function | Mean1 | Mean2 | Mean3 | Mean4 |
|---|---|---|---|---|
| 1.Selection | Key board | Voice command | System | Touch screen |
| 2.Movement | On the fixed track | Chain mechanism | Through handle rod in a fixed place | On wheels |
| 3.Detection | Number system | Bar code reader | QR scanner | Light sensor |
| 4.Medicine fetching | Robotic arm | FAMA drawn | Electromagnetic system | Hook system |
