1 Abstract:

In this project current drone technologies are observed, and demonstrated the use of quadcopter in the field of Medicine. The quadcopter is designed and modified according to handle the medical kit, and other medical needs required to the patients. The design has its own parameters and components that collectively make up the payload and drone delivery system. This report has experimental design of final drone delivery and payload design using SolidWorks.

2 Objective:

• The main objective of this Project work is to Design the Quadcopter which is used to carry the medical aid to the patient, with the help of commands given by the user.
• Increasing the load carrying capacity of Quadcopter so that the patient could get each and every thing same time.
• And to learn how to use features of SolidWorks 3D modeling software with great precession.
• To use the photo view 360 in SolidWorks and Rendering tools.

3 Introduction:

• SolidWorks:

SolidWorks is a solid modeler, and utilizes a parametric feature-based approach which was initially developed by PTC (Creo/Pro-Engineer) to create models and assemblies. The software is written on Parasolid-kernel.

• Drone:

The name, “drone” is less or more aery common name of the remote-controlled system; its reduction is UAS. In many cases we can obtain other appear such as Unmanned Aerial Vehicle but in Europe the RPA is also used name. Source is sure, the name “drone” understands for everyone however many experts wish to state it more sophisticated with UAS, UAV or RPAS.

Classification of Drones are done by undertaking so many Parameters in to consideration, one of the such parameters are selecting the number of motors to run the drone.

Quadcopter:

 From the name itself it tells that the Quadcopter has 4 motors, the 4-propeller design is simple, yet, highly versatile. Unfortunately, quadcopters don’t have any “backup” motors, so if one fails, it’s going to crash.

Quadcopter is simple in design and very cheap to build and its design is simple to understand.

This isn’t necessarily the case with hex copters, which can remain in the air even if one of their motors fail. Also, quads can’t lift heavy payloads.

                                   

Hex-copter:

From the name itself it tells that the Hex-copter has 6 motors, the 6-propeller design is a bit complex to understand, Hex-copters are fun to fly, too. They’re generally quite powerful and can lift heavier loads. Due to the increase number of motors, they’re very stable in the air.

So, if you’re getting into aerial photography, you may want to consider a hex-copter. Aside from power, it’s also easier to fly hex-copter at higher elevations (due to the increased stability).

 

             

The power and stability of the drone can be increased by increasing the number of motors, but difficult to understand the motion of drone and controlling become so what difficult by increasing number of motors.

• How Drones are used for disaster response:

Drones are already used during several disaster like earthquake and floods situations.

Ex: Drones were also used during the 2013 typhoon Haiyan in the Philippines. They were mainly deployed to survey the impact of the storm on farmlands and ascertain future risks from similar storms.

The most important thing is that we can modify the drone as like we need, this flexibility making drones to use during the disasters.

3 Design Methodology:

                                     

Fig1: Design Methodology of Assembly and Photo Rendering

The parts, which are shown above in flow chart are designed by using the latest version of SolidWorks Software. After designing Parts of Quadcopter, they got assembled by using Assemble parts option.

3.1 Assembly:

Assemble Parts option is shown directly when we start creating the new document.

                                     

Fig 2: Visibility of Assembly Option

The parts are call in to the assembly by simply clicking the insert component option, which is available in the menu. The part are inverted individually or we can call it bulk, but inserting individual is more preferrable than the bulk.

3.2 Mate:

The mate option is used mainly to set the parts of the Quadcopter in their required location. By using mate option, we give tangency, distance, coincide, or even give angle to the mating parts. We can even mate planes by using the mate option.

                                                     

Fig 2.1: Visibility of Mate Option

Mate option plays very important role during assembling the parts. The options are shown in the figure are used in assembling the Quadcopter.

3.3 Photo Rendering:

Rendering or image synthesis is the process of generating a photorealistic or non-photorealistic image from a 2D or 3D model by means of a computer program. The resulting image is referred to as the render. Multiple models can be defined in a scene file containing objects in a strictly defined language or data structure.

Rendered images has a nice graphics compared with normal assembly

are the above parts which are made by using SolidWorks 2020.

 

Sketch Tools Used:

Line:

It helps to draw a line of the graphics sketch area. In side drag menu centerline option also available. This tool helps to create center line for the 2d drawing. The centerline representation follows the engineering graphics drawing tools. The new version of SolidWorks contains Midline which helps to make lines on both sides.

Rectangle:

It helps to create rectangle box in the sketch area. In the side down drag menu, you can see the different rectangle drawing methods such as Corner rectangle, Center Rectangle, 3 Point Corner Rectangle, 3 Point Center Rectangle and Parallelogram.

Arc:

It enables to draw arc. It contains 3 arc drawing methods and they are Center point Arc, Tangent Arc and 3 Point Arc.

Circle:

It helps to draw a circle. IT contains two circle drawing method such as, center point circle and Perimeter circle.

Spline:

Splines are used in mechanical for mating the rotating parts. It is two types internal and external splines. This tool helps to draw highly smooth curves or lines of the sketch.

Straight Slot:

It helps to draw a straight slot in 3D object. It also contains arc slot tool which create an arc slot. It have two types of slot drawing methods such as centerline method, center point, 3 Point arc and Center point arc method.

Ellipse:

This tool helps to draw Ellipse on the drawing interface. You can also draw partial ellipse and parabola form the down drag menu.

Smart Dimension:

The smart dimension is one of the useful tools to create sketches as mentioned in your drawing. You don’t need to care about the dimension of the sketch profile while drawing. It will adjust using Smart Dimension tool in later action.

Plane:

It helps to insert a plane in a 3D sketch.

Sketch Fillet:

If you want to adjust the corners or make round at the corners of sketch, use the Sketch fillet tool. You can enter the fillet parameters through the property manager.

Convert Entities:

It helps to convert selected model edges or sketch entities into sketch segments.

Offset Entities:

It enables to insert the SolidWorks sketch entities offset to face or edge or curves or specified distance from it.

Features used:

Extrude Boss/Bass:

The Extrude Boss/base is one of the most frequently used tools in SolidWorks, which enables to convert a 2D sketch into 3D model. It helps to add material to your sketch files. It is represented by icon When you click on the Extrude button, the property manager opens where we can control everything about extrude.

Revolve Boss/Base:

The revolve feature enables to add materials to your 2D sketch by revolving a long as centerline or axis. The revolve boss/base is actually rotate the sketch along an axis. It helps to create parts shows the symmetry like cylinder, sphere, pulleys etc.

Swept Boss/Base:

It is sweep feature which sweeps a closed profile through a open or closed path for making solid object. This feature helps to make solid part by guiding through a definite path.

Loft Boss/Base:

It helps to create solid model between two profiles in a certain distance. It needs two or more profiles to add materials into it.

 

Extrude Cut:

Unlike the extrude boss, the Extrude cut removes the material from 3Dmodel by using a closed sketch (Circle or rectangle etc.). You can do the cut in one or two directions the using the property menu.

Revolved Cut:

Using the Revolved Cut, you can remove the material by revolving a closed sketch around an axis.

Calculations to be consider to design a Quadcopter:

The above equation represents the moment and thrust developed by the drone to move forward. The thrust developed by the drone has to be more compared with the weight of the drone in order to push the drone up.

The drone has to satisfy the two conditions in order to move linearly and rotate.

For linear motion:

For Rotatory motion:

Condition for hovering:

Condition for Rising:

Conditions for dropping:

The quad copter must follow above equations to propel further and comes to rest.
