Autonomy
Proposed Solution:
Constraints:
Visible at night and daytime (very bright)
Controllable through Ardupilot software
Autonomously without pilot input
Well integrated
Each light must be visible from 120 degrees,
need to go on ends of motor mounts and below/above arms?
4 LEDs (red, potentially blinking) one on each corner is the absolute minimum control requirement.
realism for airplane:
white strobe light (pulsing?), visible 360
beacon light, visible from 360 around. red.
red on left, green on right, white on BACK. static.
‘don’t need white on back probably'
maybe: green, red, yellow, one on each corner, based on movement.
yellow on back motors while slowing? not requirement for realism…
green LEDs on PAX aboard - if still conops req
also need to decide reflectors - these can be picked in tandem with LEDs, as adding reflectors may eliminate the need for a stronger LED, etc.
EE global constraint should be weight
save weight instead of add more brightness (if the tradeoff is reasonable)
Initial Layout Drawing
Things to Research
How will we connect to LEDs (Connector/Solder/Headers)
Need for input for Pax??
Where are we getting power from(Usually 12V) (search through architecture doc)
Ways to achieve Strobing/Blinking (555 Timers) (Parkers on this!)
Potentially ruling out neopixels
we don’t need to change colour
having too many connected to pixhawk → not great
Suitable LED strip lights should be chosen via similar setup to Decision: Type of Rangefinder for Obstacle Detection page. Can include neopixels if desired, but please compare individual part numbers.
Project Owner Availability:
@Neel Patel : 10-15h hours a week
@Parker Lawrence-Valeriani 5-10h a week - better idea of availability after midterms.
Agreed upon timelines:
Architecture plans for next week. (research and decisions)
Order components first week of November.
Full working prototype for end of November.
