Designing the Opening Component

Click to go to Sliding Doors.

There are many aspects that need to be considered when developing the mechanical system.

Planning

Completion	Due Date *a little flexible	Stage
	30-Sept	Research existing mechanisms - Doors, Sliders, Sensors, Barcode Scanners etc.
	28-Sept	Create List of Requirements this component should fulfill
	1-Oct	Make a design selection for components
	6-Oct	Detailed Sketch(es) of Component
	6-Oct	Describe how it works/each sub-components use
	9-Oct	Build mini model?

Mini Brainstorm

Stuff to Consider	Open/Close Mechanisms	Drone Landings
Weather	270-360 Door Pushed open by the lift inside or opens & closes via motor rotation; could possibly hit drone?	Beacon signal 1 When drone is in range; each pressure sends signal to designated leg for landing?
Does Drone Land or Not?	Sliding Door Opens when drone lands on platform, slides to the side out of the way of the drone	Symbols Four different symbols on pressure plates to allow orientation of drone & landing locations for the legs?
	Flap to Inside The door falls away inside the chimney rather than flips out	1 Symbol/Signal Symbol or Signal produced directly from center or one of the sides of the chimney, drone can the calculate the offset & landing location on platform

Research Questions

Scanning

Question: What kind of barcode scanners are there and how do they work?
Omni-Directional Scanner -
Fixed Position Scanner -
Require external power sources, otherwise batteries that need replacement often
Wiki-BarCode Scanners
[UPC Codes]
[Barcodes]
Barcode Scanner(s)

• MPSi system- omnidirectional or Single scanner (CRT, speed, direction, etc)

Question: What are general specifications of such barcode scanners?

• • • How fast they scan?
    • Cost?
    • Installation/ Mounting location?
    • Other necessities?
    • Can they be mounted on moving platforms?

Question: What kind of barcodes are there? What different types information can they contain?

What this research contributes to the design of this component:
(Make selection about the type of scanner that can be used & Barcode and information stored on the barcode)

Orientation

Question: How do robots/technology of today find specific locations?

Question: What are kinds of sensors that help detect contrast or symbols?

Question: Is there a beacon method that allows airplanes/drones to orient themselves to it? If so, how does that work?

Question: How are autonomous landings made?

What this research contributes to the design of this component:
(Make a selection as to which orientation method will be implemented (if any))

Transponders

Question: How is a transponder signal set? Can it be set via a barcode?

Question: How does the lock/unlock function via transponder key in a car work?

What this research contributes to the design of this component:
(If transponders can be used in the beaconing and delivering of a package via drone)

Opening Mechanism

• • How will drone open the door?
  • How will the door stay open?
  • How will the door keep rain out/from settling on top?
  • How does the door mechanism work?
    • 1 vs 2 doors, pop up or slide aside,
    • Will it hit the drone?
  • What kind of mechanical sliding doors are there
  • Can it hold the weight of a drone?
  • Where does the power come from to run the system?

Fixing/Maintenance

• • How robust is the system?
  • How does it send an error signal?
  • How can a person fix the mechanisms?

Environmental Concerns/Requirements

• • What are the minimum and maximum heat withstanding of the subcomponents?
  • Are the components water proof?
