We strongly suggest building the car with raspberry pi to minimize cost. Bill of materials is as follows:
| 1. Car | $90 |
| 2. USB Battery(to power up raspi)* | $10-$20 |
| 3. Raspberry Pi 3B+ | $38 |
| 4. MicroSD (at least 64 GB preferred) | $18.99 |
| 5. Raspberry Pi wide-angle camera | $25 |
| 6. Servo Driver Board | $12 |
| 7. M2x6 Screw | $3.5 |
| 8. M3x10 Screw | $7.89 |
| 9. Female to Female Jumper Wire | $7 |
| 10. 3D printed chassis ( see instructions below) | Varies |
You can print the chassis in college if your department approves it. You can also order chassis from the official donkey website which may cost ~$82. It is also possible to order to a 3rd party manufacturer. There are lots of 3D printing manufacturers who may 3D print the chassis according to your color and materials & ship it directly to you. Depending on material & color it may cost ~$50.
