I’m a third year Mechanical Engineering and Industrial Design double degree student. My passion is computer design and technology in general. I am looking forwardto developing my design capabilities using computers as that is where I feel most comfortable. I started designing and building at a young age but only really have approached this skill more directly since starting at RMIT.

DRONE DEVELOPMENT FOLIO


I began my drone with inspiration from race cars and using the elements of sleek design and fast lines, I came to a form that Ithought covered those elements.

I created a unit for holding each of the individualmotors and shaped it to howI felt it would best contain the motors. The top component of the motorholders is detatchable in order to remove motors ifthey break.

After creating the form,I then built the �rstcomponent, the arms ofthe drone. This would bea necessary componentfor my next step.

After designing the form ofthe drone, I decided that in order for the motor unitand arms to hold together,I would need to constructa latch. This latch wouldbe constructed outside ofthe motor enclosure. This would allow for the arm,motor and cap to be heldtogether.



After completing the arm, I then moved onto creatingthe lights for the drone.Car headlights became myinspiration. The form and appearance is well suited for the body of the drone.

I followed a lot of queuesfrom car headlights and how they are designed and manufactured to create the lights.

I built the camera for my dronearound a general drone camerawith a 1 axis rotationalmovement camera. The shape was inspired by compact cameras such as GoPro’s andother drone cameras.

I designed my power button,which will light up when the droneis powered on. I also included a 4stage battery charge indicator.This would be helpful to usersbecause it will indicate to theusers if the drone is out of poweror malfunctioning.

The lights would bemade from conventionallight globes with a plastic shell insert and clear protective acrylic.



I built in a LiPo battery for the drone as it’s main power source.This battery type would bebene�cial to the user becausethe battery will be detachablefor recharging.

I designed the drone to be pulled apart for maintainenceso external screws to openthe chassis are required.The main design feature ofthis drone is all majorcomponents are replacablein the event of a malfunction.

I added small ventilation holesin the battery pack and inthe arms of the drone in orderto allow for the hot components to disperse theheat to the environmentwithout needing fans throughout the system.

Webbing was included, where possible,to create a better structural integrity.This increases the durability and reduces the �ex in the body. Thisalso provides the drone with increased crash resistance.

Each of the components would be made as a die-cast plastic mould and the screws areOEM screws.



I then inserted a PCB into the drone which is fastened to thebottom of the chassis. This creates a base layout for theconnectors to all the components not found on thePCB.

Using general wiring convensions such as red wiresfor power, black for ground and yellow for communication, Imade wires to each of therespective components throughout the drone.

At the front end of the drone,the wiring became a lot morebusy with connections to eachof the front motors, both thelights at the front, the batteryand camera.

Once I wired up all the majorcomponents, I chose a colourpalette that I felt suited the fast and sleek appearance. I then attached my motorsto the PCB and began torender my drone.



I attempted to make a propeller for my drone, however I found this toodi�cult. I downloaded a premade propeller and thenbuilt the motor for it. Istarted by creating a shaftand the skeleton of a DC motor.

I then created a coil that goesaround the skeleton which was arepeated loop and copied along the length of arm to create acoil appearance.

I then repeated the coil around each of the arms, added bearingsto either end and threading thetop to allow for the propellerto attach onto the motor.

The coils are made of copperwith the shaft being made outof hardened steel with deepgroove ball bearings to allowfor minimal resistance in the motor. The propeller will bemade of �breglass in orderto be strong and light weight.

DRONE RENDERING FOLIO


EXPLANATION AND REFLECTION


The skills which I built the most were structuraldevelopment and �ne detail understanding inthe model. I also wanted to develop my renderingskills in this model and use custom backgroundsto produce the most realistic renders with my current experience and skills. Overall, the droneallowed me to explore creative options and helped me to understand the inner workings of a drone.

Through the design and development of thedrone, I have developed my creativity skillsin being able to make an attractive drone that isbuilt with structure and intent for everycomponent. The drone also helped mein understanding connections betweencomponents and to think clearly about what isrequired to connect every piece.
