New ELRS Hardware Project

• @Nolan Haines please do some research and put questions here to be addressed during the meeting, this meeting is agreat time for integration discussions like this!

• TABLED

EFS

ELRS Configuration

Testing gemini - gathered ardupilot telemetry, but link stats were (only) from TX16-EP1 (logs on blue controller that are not yet uploaded). Were not getting link qual/receiver strength/ to diversity signal strength - so modify gemini firmware to take link stats on gemini board → package AFTER ardupilot stats → able to see this telemetry.

• to recap after meeting?

• will be instructions to gather stats and test it more in-depth this weekend

Mech

Sensor mounts?

• need OFS + Rangefinder mount for houston

Received documentation for this, will give out this task at meeting tomorrow

~~ probably a few days before feb 10

Electrical

Sensor harnessing

• ^ see above.

Optical Flow (OFS)

Rangefinders (Sonar/Lidar/Radar)

EFS

Optical Flow & Rangefinder Calibration

Specifically for houston

see if the issues with tuning pegasus are replicated on houston

~~ probably a few days before feb 10

Autonomy

Mech

Mounting

VTX mount to be reviewed, forwards-facing camera mount ready to be printed.

• printer small difficulty, print in RPC or something

feb 10!

Electrical

VTX harnessing

• vtx are in. Should be wired for feb 10

camera, mux, transmitter.

See architecture docs from this year/last year for ‘video system’/'vtx'

two camera → Mux → OSD → VTX

EFS

Ardupilot VTX mgmt

No update. TODO still.

Autonomy

LTE Video?

Possible / ready to FT early march?

Mech

RFD Board

• @Yuchen Lin to add updates regarding this!

Board is ordered! ~~ (TBD) maybe next friday will arrive

EFS

Gemini

• prepare comp-ready spec

  • power connectors soldered on to gemini board

  • build connectors for this thing on the gemini board

  • ep → gemini uart connection soldered

  • add fan with soldered connections

  • u.fl to sma adapters

  • case to house system(gemini, ep, fan, battery?)

• Need telem from Gemini board (linkstats appear to be EP1 ↔︎ TX16)

  • See above

Have 3 boards - get enough connectors for all 3. make sure they are all competition-ready

Not required for this weekend’s FT - gemini ‘safe to fly’ as it is

deadline is ‘as soon as reasonable’ - can do in the 2-week FT gap in feb

ELRS / ardupilot channel mapping

See 2024-01-22 AEAC Sync

during wednesday evening EFS ppl working

• update controller FW

• update pink controller to have different channel mappings

Mech

Pegasus

Pegasus 2.0 construction has begun, one carbon fibre plate has been made over the weekend. got drawings for the lighter center block

• nice new carbon fiber

Prop clamping blocks are going to be printed and tested

Cabin construction will start soon once parts are finished being machined. Cabin projected to be on the frame by this weekend!

people working on upgraded landing gear designs

Houston

Houston is out of commission mechanically atm, houston tests need to be on hold until the landing gear and lidar mount are replaced - @Alison Thompson

• maybe by feb 10 we have a new and improved lidar mount

Houston landing gear request via @Anthony Luo

• couple times houston tips over when it lands

• requesting landing capability while in ‘slight translational motion’

Limited on weight. In short-term, current version can be remade. Can get someone on adding more support.

• what flight weight does houston need to stay under?

  • @Megan Spee @Anthony Luo to find an answer (or do this properly)

  • either test this IRL or just pick a nice number

Electrical

LED Board

• @Parker Lawrence-Valeriani Please add an update regarding status of board and plan for EFS handoff

• board is ordered (same as RFD order date)

• no meme on this board

Tracking Antenna Mechanical

Parts are being ordered for the large tracking antenna, on track to be completed by agreed upon timeline of late Feb/early March, CAD is complete for the most part. Still need to redesign servo mounts according to @Nathan Green .

Summary: Servo L-sheet metal are too long in length. Cannot bring screws in due to tripod interference. Need to create a mount that screws in through the middle. Any objections?

Open

Electrical

Nucleo Shield

• @Nolan Haines @Michael Botros Please update this document with status and your questions (they can be answered async, ik u guys have work lol)

• Current status

  • Schematic done, board layout is close to being done.

  • There will be some changes to the overall board to make it smaller and more compact.

  • Currently rewriting all the documentation for the board for readability.

• Questions:

Check mechanical’s documentation on tracking antenna before proceeding!

If questions are not answered please Check arch doc/ offline submit to mechanical

• I basically wanna make sure tracking antenna PCB can support all of our ground station towers, is there a link or place with a list or block diagram of our different towers?

• Will tracking antenna have enough and all the proper connectors to support different peripherals on the tower?

• Currently for VTX tower, tracking antenna only supplies 12V power, is this all thats needed from tracking antenna or is more connectivity needed?

EFS

Arduino Tracking Antenna

• They figured out how to forward the mavlink message on Mission Planner

• Heard that the tracking antenna works in the simulator

• Aryan tries to add the gps to the code instead of hard code location of the tower

• Concerning of the servo, doesn’t work if angle > 180, hope to get a contiunous servo

• Should be good to flight test

Will probably complete ground testing this week and implement in flight test for feb 10. Not a huge rush but can speed up this timeline if people are interested in doing the work early.

looking for whether or not the data rate is good enough to keep the antenna pointed at the drone. So can gather this data without actually putting it on the flight line.

Budgeting: pick the lowest price point you can get away with

You need to receive corrections data from the RTK thing and send it to the GPS…

get higher quality/newer M8/9/10s or GPS in general

Autonomy

FIND PILOT (especially if on-stream in the summer )

• will sponsor advanced rpas test (once) + ground school

thx for listen
