AbstractThe purpose for this project is to design a portable product, which can produce an impactful, and revolutionary that could help more Malaysians in facing the major disasters and accidents. The design consists of a quad copter with a camera and a clamp, which carry lifebuoys to save the victims that trap in flood or sea accidents. During the flood or sea accidents occurred, the quad copter will release the lifebuoy to the victim. During the design process, many consideration should be taken. For instances, materials of quad copter, cost, weight, corrosion and others has been take in consideration in order to produce an optimum quad copter which can ease the life of Malaysians who faced the major disasters and accidents.

1.0INTRODUCTIONStart from 14 December 2014 to 3 January 2015, more than 200, 000 people affected and 21 of them killed on floods in Malaysia (Source). During the floods in northeastern Malaysia on 20 December 2014, 25000 people have affected, 4 persons drown and died, and the saddest accident was a 20-month-old baby girl fell into the floodwaters after she slipped from her mothers arm (Ng, 2014). In 2000, floods killed 15 people in Kelantan and Terengganu during year 2000 and 28 people in Johor during year 2008 (source). Another statistic estimates 700 people drown every year caused by flood in Malaysia, which has an average of 2 people die from drowning every day (Ooi, 2014).The above statistics showed that the flood brought the impact on human population in terms of mortality and injury. Most of them drowned and died without any immediate rescue action conducted. There are many limitations for the rescue teams to reach the destination of the flood immediately to rescue the victims. Since flooding always involved larger areas, it also increased the difficulties for the rescue teams to conduct the rescue action. Hence, it takes the rescue teams a lot of time to search and rescue the victims.The purpose for this project is to design a portable product, which can produce an impactful, and revolutionary that could help more Malaysians in facing the major disasters and accidents. There were a few highlighted major tragedies happen in 2014 in Malaysia. On 8 March 2014, the Malaysia Airlines Flight MH370 was missing and 239 people killed in this accident. In the same year 2014, another flight accident happened, Malaysia Airlines Flight 17 carried 295 people was shot down and crashed with no survivors. In addition, several parts of Kelantan, Terengganu, Pahang, Perak, Perlis, Sabah, Johor and Selangor were hit by flash floods on 4 December 2014.That had classified as the worst flood disaster in the Malaysian history.

2.0 OBJECTIVEThe objective for this project is to design a portable product, which can produce an impactful and revolutionary that could aid more Malaysians during facing the major disasters and accidents.3.0 DESIGN BACKGROUNDEvery year, there are many people die when flood because of lack of an efficient and fast way to give them a hand while they are drowning. One of the traditional way to rescue drowning victim is always by throwing the lifebuoy to him/her from the rescue boat or swimming toward the victim. This method is lack of speed and accuracy when the rescue is carried out. It is necessary for inventing a vehicle or robot to replace humans speed and accuracy for performing the rescue action.A quad copter is a multirotor helicopter that is lifted and propelled by four propellers. Normally quad copters are classified as rotorcraft as their life is generated by a set of rotor which are opposed to fixed-wing aircraft. There are few advantages of quad copter that had brought to this design. One of the advantages is small-scale quad copters have frames that encloses the rotors, allowing flights through more challenging environments and with lower risk of damaging the vehicle or its surroundings. Besides, quad copters do not require any mechanical linkages to vary the rotor blade pitch angle for spinning. Hence it simplifies the design and maintenance of quad copter. The use of four rotors allows each individual rotor to have a smaller diameter than the equivalent helicopter rotor, which allow them to possess less kinetic energy during flight.Therefore, based on the advantages of the quad copter had brought the idea by combining with a clamp to hold lifebuoys and rescue victims during flood happening.

3.1 Design ConceptThe design consists of a quad copter with a camera and a clamp, which carry lifebuoys to save the victims that trap in flood or sea accidents. For the clamp part design, the arms of the clamp are designed in a cross shape as the clamp can support two lifebuoy once in the flight time. Furthermore, the design of the clamp part also allows the quad copter used to collect back the life buoy after the rescue operation. The arms of the clamp will extend to carry and hold the lifebuoy along the way searching for the victims. The arms of the clamp will move inward in order to release the life buoy to the victims from a specific height. Hence, the lifebuoy will drop to the side of the victim in spite to rescue the victims. During the flood or sea accidents occurred, the quad copter will release the lifebuoy to the victim when the rescue team worker receives the images from camera, which install at the quad copter. Then, the operator will remotely control the clamps manually which allow the quad copter carry and hold the lifebuoy travel along the way finding the victims (Diagram 1 attached in Appendix). The lifebuoy will release automatically by move the arms of the clamp inward to rescue the victim who are found in the sea and nearly drown (Diagram 2 attached in Appendix).

4.0DETAILS DESIGN OF CONCEPTThe following design details consists of the lifebuoy, quadcopter, propeller, electrical components, motor, and clamp. 4.1 Lifebuoy Lifebuoy is a circular ring to increase peoples buoyancy to prevent drowning. There are three standard sizes of lifebuoy that are listed in International Convention for the Safety of Line at Sea (SOLAS) 1974, and amended in 1983 (Marine, 1992). Table 1 shows the different types of standard rescue life buoys.Table 1: The types of lifebuoysNo.CodeOuter diameter(mm)Inner diameter(mm)Major axis (mm)Minor axis (mm)Mass, m (kg)
