INTRODUCTION

Pet owners usually have difficulties in feeding their pets regularly. For

example, when they go to work or go to holidays, they have no time to feed their pets.

Being too busy also causing many pet owners to forget feeding their pets.

Animal sellers find it time and energy consuming to feed all the animals when

the numbers of animals are large. In order to ensure the animal’s growth, animal

sellers must make sure food supply is continuous.

To solve those problems, our product is designed as a new product to be sold

at a cheap price at local market.

OBJECTIVE

To produce a machine to feed pets like cat, rabbit and dog automatically.

ADVANTAGES OF THE PRODUCT

Easily moved because the machine is light.

Work automatically with the power supplied by battery.

Low cost because build up by used material.

Easy to be used due to simple circuit.

LED can be used as accessory.

BENEFITS

The pets will not starve because the food is always supply.

Growth of the pets is guaranteed.

The owner of the pets no need too worry if they not at home.

MATERIALS

1. Switch 6. Motor

2. Battery and holder 7. Pet’s food

3. Plastic bowl 8. Plastic container

4. Wire 9. Wood

5. LED 10. Spring

PHYSICS CONCEPT

Electric circuit – battery supplied the power so that the circuit is complete and

machine is working.

Hooke law – the spring is used as a switch by compress or expand process.

OPERATION METHOD

AMMO

3

No food

Spring will extend, and then switch is open.

Complete circuit.

The motor will rotate using battery to open the container.

The food will flow out to fill up the bowl.

The spring will compress, and then the switch is close

(food stop flowing out).

PENGENALAN

Kebiasaannya, pemilik haiwan peliharaan mengalami kesukaran dalam

memberi makanan kepada haiwan mereka apabila mereka tiada di rumah. Sebagai

contoh, apabila mereka keluar bekerja atau pergi bercuti. Kesibukan bekerja

menyebabkan pemilik haiwan kadangkala terlupa untuk memberi makan kepada

haiwan peliharaan mereka.

Penjual haiwan pula mempunyai masalah dari segi masa dan kos untuk

memberi makan kepada haiwan yang hendak dijual disebabkan jumlah haiwan yang

terlalu banyak. Makanan hendaklah sentiasa mencukupi bagi memastikan

pertumbuhan haiwan-haiwan tersebut terjaga.

Bagi menyelesaikan masalah-masalah tersebut, kumpulan kami telah mereka

satu alat memberi makanan secara automatik yang akan dijual pada harga yang

berpatutan dan dibina menggunakan barangan terpakai..

OBJEKTIF

Objektif kami adalah untuk menghasilkan alat memberi makan kepada haiwan

peliharaan seperti kucing, arnab, ayam, tikus belanda atau anjing secara automatik.

KELEBIHAN ALAT

Mudah dibawa ke mana-mana.

Alat yang ringan dengan binaan yang ringkas.

Beroperasi secara automatik dengan menggunakan kuasa bateri.

Kos yang rendah kerana diperbuat daripada bahan terpakai.

Menggunakan litar yang ringkas.

MANFAAT

Haiwan peliharaan tidak akan kelaparan kerana sumber makanan yang sesuai

sentiasa dibekalkan.

Pertumbuhan haiwan terjamin.

Pemilik haiwan peliharaan tidak perlu risau akan haiwan pelihraan mereka

apabila tiada dirumah.

BAHAN-BAHAN

6. Suis 8. Papan lapis

7. Bateri dan pemegang 9. Spring

8. Bekas plastik 10. Tali bergetah

9. Wayar 11. Klip kertas

10. Motor 12. Paku

6. Pita selofan 13. Mangkuk

7. Makanan haiwan

KONSEP FIZIK

Litar elekttik – litar menjadi lengkap apabila suis tertutup dengan bekalan

kuasa bateri untuk membolehkan alat berfungsi.

Hukum Hooke – Spring digunakan untuk proses regangan dan mampatan

semasa suiz tertutup dan terbuka untuk membolehkan

makanan keluar atau berhenti.
