Essay on Drones: Unmanned Aerial Vehicles for Delivery, Surveying & More

Introduction

Drones are also referred to as Unmanned Aerial Vehicles (UAR). They are remotely controlled aerial objects that can fly into the sky. All drones have two parts; the Drone itself and a control system. The use of drones has significantly increased over the last few years. Today drones are commercially used for many applications, including surveying of construction, media coverage, professional photography, and delivery of products. In delivering these roles, drones have to carry some load that will carry out the commercial purpose of the Drone. For example, for media coverage, a drone has to take a camera and a microphone with it high into the sky to collect the essential news.

However, in all items that fly into the air, safety is paramount. It is important to understand the correct amount of load that a done can carry to avoid possible accidents due to overload. In this drone flight experiment, we shall seek to understand the best load amount a drone can carry to ensure safety.

The question I want to investigate

This drone flight experiment seeks to answer the question: What load amount can a drone carry to ensure safety?

Study hypothesis

The drone flight experiment will test the following hypothesis.

H0: Drones cannot safely carry a load equivalent to their weight

H1: Drones can carry load weight equivalent to their weight.

Experiment to Practically Test the Hypothesis

To practically establish the mass payload limit a drone can carry safely, a drone weighing 2.5 kg will be used. The experiment shall require the following materials.

Materials

• A fully functional drone
• Strings
• Rubber bands
• 6 Weights each measuring 0.5 Kgs.

Procedure

Make sure all the materials for the experiment are available

Fly the Drone alone without any weights or any extra load attached to it and records its ability to launch and maneuver in the air. The ability can be categorized as good, fair, poor, fail. Record the findings in the table below.

Fly the Drone alone with a 0.5 Kgs weight extra load attached to it and records its ability to launch and maneuver in the air. Categorize the ability to launch and maneuver as good, fair, poor, fail. Record the findings in the table below.

Fly the Drone alone with a 1 Kg weight extra load attached to it and records its ability to launch and maneuver in the air. Categorize the ability to launch and maneuver as good, fair, poor, fail. Record the findings in the table below.

Fly the Drone alone with a 1.5 Kgs weight extra load attached to it and records its ability to launch and maneuver in the air. Categorize the ability to launch and maneuver as good, fair, poor, fail. Record the findings in the table below.

Fly the Drone alone with a 2 Kgs weight extra load attached to it and records its ability to launch and maneuver in the air. Categorize the ability to start and move as good, fair, poor, fail. Record the findings in the table below.

Fly the Drone alone with a 2.5 Kgs weight extra load attached to it and records its ability to launch and maneuver in the air. Categorize the ability to initiate and move as good, fair, poor, fail. Record the findings in the table below.

Fly the Drone alone with a 3 Kgs weight extra load attached to it and records its ability to launch and maneuver in the air. Categorize the ability to launch and maneuver as good, fair, poor, fail. Record the findings in the table below.

Collected Data

Trial 1 UAV only Trial 2

UAV + 0.5 Kgs load Trial 2 UAV + 1 Kg load Trial 2

UAV + 1.5 Kgs load Trial 2

UAV + 2 Kgs load Trial 2 UAV + 2.5 Kgs load Trial 2 UAV +3 Kgs load

Mass - 0.5 Kgs 1 Kg 1.5 Kgs 2 Kgs 2.5 Kgs 3 Kgs

Ability to launch Good Good Good Good Fair Poor Fail

Ability to maneuver Good Good Good Good Fair Fail Fail

Payload Mass 2.5 Kgs 3 Kgs 3.5 Kgs 4 Kgs 4. 5 Kgs 5 Kgs 5.5 Kgs

Conclusion

From the above results, it is evident that when the UAV fly without any extra load attached to it has a good ability to launch and maneuver in the sky. If the weight of only 0.5 Kgs is attached to it, the Drone still has a good ability to initiate and maneuver in the atmosphere. The same happens when the UAV is assigned loads of 1 Kg and 1.5 Kgs.

However, when the UAV is attached a load of 2 Kgs a weight 80 percent of the Drone weight, the UVS's ability to launch and maneuver in the sky reduces to a fair. On adding a 2.5 Kgs weight to the Drone, which is also 2.5 Kgs, the Drone's ability to launch is very poor, and it fails to maneuver in the sky. Attaching a weight of 3 Kgs to the Drone a weight above the weight of the Drone, the Drone fails to launch and cannot maneuver in the sky.

From the above data, it is evident that a drone cannot safely carry a load equivalent to its weight; hence the experiment findings confirm the null hypothesis that drones cannot safely carry a load equivalent to their weight.
