Designing the Opening Component

Click to go to Opening.

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

Totes expected to be handled p/day:

Time Spent handling a tote:

Tote has barcode located in bottom right corner of the tote on both the front and back face, simplifies orientation problem.

Problem Description

Factors/Constraints

Environmental Factors	Dynamic Factors	Technical Factors
Rain	Birds	Waterproofing?
Snow	Bugs	Moisture Resistance?
Debris		Temp. affects on function?

Tasks / Functions

Task/Function	Description
Positioning	Drone+/or Package reaches the correct place for dropping the package or entering the system
Identification	package+/or drone needs to be identified by the system so that it can further handle the package
Accuracy	drone landing/dropping of the package should be accurately placed in the landing zone
Speed	The rate at which a package should be handled to the next stage of the system
Size of Landing Zone	The size may effect accuracy of package dropping (want to make this as large as possible)
Flight Path Problem	How many DoF does the drone have to approach the opening?

Assumptions:

• Drone has Obstacle Detection to avoid objects in its way

Research Questions

Identification

Question: What kind of identification methods are there and how do they work? Radio Frequency Communication

Barcode Scanning
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)

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: What kind of methods are there to position robots/carts/etc. and how do they work? Landing Radius casting Light Beaconing Transponder signal? RFID

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

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

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)
