The Weekly Recap
Flight Tests:
Vanny SUCCESSFULLY completed auto-tune
Noticed thrust loss on Motor 3 after Battery Failsafe → Investigation ongoing.
This is (not) expected behaviour.
CV Landing pad detection works.
GPS not tested.
New arrivals
Cool things we did
ELRS Airport working (very slow though)
Open action items
Meeting minutes
Tracking Antenna
Tracking Antenna Tower
Mechanical
Yaw only looking good.
Will look @ 3s
Going to add some angle on yaw only
on pitch version, going to add default is level and ability to pitch up and down.
Building the antenna starting this week.
Using the tripod.
No counterbalance for the yagis (fine for yaw only).
HS 785 HQ, 8 rotation servo
gearbox is 1:7
will need calibration for this later (in software)
Tracking Antenna Nucleo Shield
ELECTRICAL
component selection undergoing
we have a new member joining this project @Rukshi Thiyagayogan
Integration almost complete. BMX tested, NEOM8 not tested.
PID not started….
Tracking Antenna Software
Embedded Flight Software
integration code finished
have a blocker: not finding neo m8 but solved today
will warp up the integration test
continue on pid motor code
WILL WRITE UNIT TESTS
ELRS
Gemini
ELECTRICAL
Slightly behind schedule
Electrical schematic in its last stages
missing some connector clarifications
Planning to ask in ELRS discord
Research new component to replace PCB antennas
Will require a schematic review
Potentially other EE members or leads
Also planning to review in ELRS discord
PCB design phase hoping to start this week
Will ideally be able to give some dimensions and sync with mechanical soon for JR module mechanical design
Gemini communicates over UART.
Antennas for ESP are mostly meant to flash firmware over wifi / OTA updates
Going to do RS422 now, looking for Wireless in the future.
if doing wireless - it can be UART.
Gemini communication needs BOOT0 connection (to update over wifi).
may need to use push-button // jumper
Normal communication just uses UART.
Airport
EMBEDDED FLIGHT SOFTWARE
< updates here >
Hardy looking to create wireless function for RS422, will contact Farris to get more info.
Ground Station Software
AUTONOMY
Data Telemetry working & tested.
Working on GUI.
IMACS
working on testing stuff through TCP.
Once serial port working, and GUI done, need to test on drone // ardupilot.
Minipix possible?
QR Code detection
Focus rn
MAVLink commands
Focus rn
Airside Command & Control
LTE Communication
integration
< probably not much to update but updates here if there are any >
Jetson Autonomy
Autonomy
All tasks given out, architecture created and finalized.
all independent tasks completed by saturday.
week after is integration
flight test on saturday post next (22nd).
GeoLocation
Needs to be refactored.
Merge-odometry-and-detections module
Dronekit on Jetson
Dronekit on jetson PR just reviewed.
trying to keep in common repository (ground and airside). Reduces boilerplate.
Control Passthrough
Embedded Flight Software
MAVLink
