Tracking Antenna 🗼

Tracking Antenna Tower

titleMechanical

Yaw only looking good.

Image Removed
  • 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)

    Added 3d printed parts to angle YAGI antennas (25 degrees)

  • angled backplate for patch antenna (25 degrees)

  • Built over the weekend.

  • Only need to finish the backplate for backplate and laser cut lexan rotating platform to house electronics.

    • waterjet not working the past few days. Will be up and running sometime today or tomm.

  • ETA EOW

Tracking Antenna Nucleo Shield

titleELECTRICAL

  • Started working on drawing the schematic of the tracking antenna pcb

  • Yuchen Lin Found out the prototype board he soldered wasn’t really working

  • We are currently making a new one with better planning, more careful soldering, and easier to use

Tracking Antenna Software

Status
colourRed
titleEmbedded 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 TESTSEvery driver finished

  • Sensor Fusion for BMX160.

  • Need ground testing for decoding MAVLink GPS.

ELRS 📶

Gemini 📻

Status
colourYellow
titleELECTRICAL

  • 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.

      Just started PCB phase

    • Image RemovedImage Added

      Board will likely not be ordered before the end of the term

      • Will need to be tested early next term

    • Boot jumper, UART connection for data.

    titleIntegration

    • CRSF from TX16 ↔︎ TX is the same as CRSF from RX ↔︎ FC

      • Will use ELRS as “hop” to Gemini board.

    Airport 🛫

    titleEMBEDDED FLIGHT SOFTWARE

    < updates here >

    Hardy looking to create wireless function for RS422, will contact Farris to get more info

    • Have figured out how to run their unit test today

    • Looking at implementing the telemetry burst in the airport first

    • If this work, the bandwidth of the airport can potentially double

    • The telemetry burst already existed in the code base but was unused because they think it need more testing and might be unstable

      • potentially range tests….etc.

    Ground Station Software

    Status
    colourPurple
    titleAUTONOMY

  • Data Telemetry working & tested.

  • Working on GUI.

    Mission Planner

    • Full flight test in simulator on Autonomy Desktop

    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 rnWorking out details on data telemetry.

      • Working on clean architecture && making FIGMA GUI.

      • Have plan on what needs to be displayed.

    titleAutonomy

    • 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

      Working on finalizing dronekit python integration into autonomy cv system.

    • Working on getting geolocation module support

    • assigned out QOL tasks to make working on the Jetson easier (during flight tests).
