Cost Breakdown

We built this micro mouse using many devices and tools.

Component cost breakdown：

1. Two touch bars
2. Two motors
3. Two wheels
4. Several wires, approximately 4 meters long
5. Eight LED lights
6. Two plastic boards and one wooden board
7. Several nails and nuts
8. One micro servo
9. One DFplayer mini
10. One buzzer
11. Six 100nF capacitors
12. One 10nF capacitor
13. One CD4093
14. Three 1N4148
15. Two 1M resistors
16. Six 10k resistors
17. Three 330 resistors
18. One 47k resistor
19. One 62k resistor
20. Three LDR
21. Four transistors
22. Approximately 200 grams of 3D printed plastic
23. One micro controller
24. One battery

Roughly estimated to be around 122.4 pounds

Next is the estimation of indirect costs:

1. The laboratory provides six hours of time per week, with two semesters added together and additional time, resulting in approximately 70 hours of time.
2. During the construction process, we consulted many instructors and professors
3. We used soldering tools, screwdrivers, wire cutters, laboratory computers, electric drills, and other tools.
4. 3D printing of approximately 200 grams of plastic

Our estimated price is 1460 pounds

Total completion time：

As mentioned earlier, it took approximately 70 hours to develop Micro Mouse, plus the website development took approximately 80 hours.
