Electrical
Tracking Antenna Controller
found root cause why the buck chip doesn’t work
our schematic
applied a fix, but buck still doesn’t power up
to unblock efs, we are gonna solder the seeduino & display on a brand new board, and inject 5V at buck Vout to provide power
timeline unknown
@Andrew Chai to follow up with @Ryan Scomazzon
how to unblock EFS now
Path toward descoping complex features and ordering November 1st
Kenny is up to do this if no ee bandwidth - @Daniel Puratich down to PM here
Video System
https://app.asana.com/0/1208217874711985/1208523962860761/f
does this task mean we need to add a wire from pixhawk gpio to camera mux?
yes
@Nathan Green
@Andrew Chai what is plan with Tom’s board for unified video system
Lighting Board Rev 3
4x boards have all been validated and handed off to EFS
done on ee board assembly side
needs firmware then will get mounted
would be nice to get it on the drone for a photoshoot after midterm or wait for payload
RPi Board Rev B
@Daniel Puratich completed bringup, integration, and testing last week validated fully with autonomy team
2x boards, one for Houston, one for Pegasus 2 are ready
One on Houston is fully installed, but both are fully validated and identical
simple board, absolute winning on this one
maybe need to order more of those headers
@Daniel Puratich covered
Embedded Flight Software
@Hardy Yu made it late
How is AP_PERIPH integration going?
yesterday we agreed this was path forward
no progress since then
Lighting Board Code
five of six light up, firmware issue
try to get the HSE going
Tracking Antenna Status
there’s people who are working on it
testing with mavproxy
Gemini Stuff
having weird problems
only two boards are working kind of, one isn’t tested
target use is for tracking antenna, unsure if this is real competition
Mechanical
Task 1 Solution
camera mount
Gimbal for Task 1 ?
is this necessary? we can look into but need to know what camera ASAP
necessary is probably not, but maybe gets us more points depending on how they do the physical obstacles
will gimbal mess with location if camera moves relative to drone
easiest to do this on peggy 1 so we don’t need to take payload on and off for peggy 2, thoughts?
gimbal over complicates, no gimbal
only one camera, pointing doward, POR for now
Peggy 1 Stuff
harder to bring up to peggy 2 spec because different electronics on it right now
Tracking Antenna Status
ready for EFS!
Task 2, hovering bonus points?
may be possible with current designs if we do the first delivery when the water level is high, may have to take an L on a smaller amount of water for that one delivery
Planning on making both payloads and choosing at end of term
both inexpensive
gives backup if something happens
lets designers have a physical product at end of term for portfolio, more gratifying
can test both and see which we like more
Using this pump for now: 8x7x6 Qqmora kd-28 Water Pump 12v Food Ultra Quiet Mini DC 12V 12W White Food Grade Brushless Submersible Water Pump 3.5m Lift Head
2 A, pretty chill
Choosing a relief valve by the weekend to order and test
need a float as well
Electrical
Can do a low side FET and a flyback diode for both of these
need to ensure we can’t put 12V into the pixhawk because that will kill it.
Perf board something together to verify this solves
relay is really heavy
IMACS monitor mount will be done this week
Autonomy
What is IR Camera POR?
@Mihir Gupta ordered 3 Raspberry Pi IR Cameras
These are ordered so that we have something to test with
We can purchase other cameras if needed but these are intended as a starting point for now
What is task 2 autonomy plan?
@Maxwell Lou to loop back next meeting
Geolocation Testing plans
Email to follow up with Teledyne to be sent out tomorrow morning.
draft in there
just tell them path forward
Flight Tests
for discerning between Houston and Dallas
didn’t test anything last weekend
how we plan on doing things in the future to get better!
review the FT doc
Upcoming FT before midterms
are we all happy with this plan?
review the FT doc: 2024-10-12 Houston Geolocation Test
We don’t have apilot, Nathan it is ….
Right After Midterms
what is in scope here?
walk through the Asana to plan tests for the rest of the term
None over midterms week for sure
Future Pilots
need stream stuff to line up otherwise testing during winter will be really hard
for eclipse started convo here but need someone to step up for peggy
Comp Organizer Questions
Will we get a known location GPS beacon?
Can the 3 meter requirement be relaxed?
What sensors and at what times will the locations of the IR beacons be determined by the organizers?
