RFC for new batteries

see ‘updates’ above

Electrical

4 battery harness configurations

are we good with the + configuration for 4 batteries

• battery harnessing cleared up over the weekend!

EFS

Bidir DShot verification

• Will be assigned to EFS flight test prep team once flight-test critical tasks are completed.

Controls Tuning

• Also to be completed once current flight-test critical tasks are completed. Includes a re-examination of:

  • attitude controller (autotune)

  • Altitude controller

  • Position controller

Mech

Sensor mounts

• Pegasus mounts for rangefinder and op flow have existed for a while

• Lidar mount for Houston exists, just needs to be mounted

• working on the following

  • 360 pegasus lidar

• No plans to change current monster mount. Subteams to notify mech if rev. necessary

• No further plans for sensor mounts on Houston

Electrical

Sensor wiring

• op flow & rangefinder sensor wiring checked on Pegasus

• waiting for mech on 360 lidar

Conformal coating on PCB

• Need clarity on motivation behind conformal coating:

  • is it for waterproofing?

  • Which PCB’s will require conformal coating

  • Will having housings for PCB’s make conformal coating redundant?

• sensors on monster mount may need conformal coating

EFS

Sensor calibr & quality test

• No calibration for the sensors has currently been done.

• Need guidance/pointers on how to do calibration and testing

  • What specific metrics need to be calibrated?

  • What metrics are to be tested and against what values?

Rangefinder support on Houston

• Needs to be supported in SW for Houston

  • will need mech mount, EE conformal coating, and a bit of configuration

Autonomy

Sensing

monster mount holds the camera. Not in a position to test the camera yet - need geolocation working before putting it on Pegasus.

Will take place after ground testing with geolocation

Mech

VTX Mount

making a new one - not very urgent, someone is working on it

VTX Antennas

mount for antennas for VTX system

• to be RFC’d into the arch doc. needs testing and placement first

Electrical

Harnessing (airside)

• waiting on procurement order

Harnessing (groundside)

• New rev. waiting on procurement

• Old Rev. still assembled on antenna tracker prototype.

more information - check arch doc or EE-specific wiring. Will reach out to people to get a better handle on this project.

EFS

Ardupilot VTX mgmt

• Clarify requirements

  • What is this task, and what is the end goal?

  • Are there specific steps/action items that EFS should follow?

resources/requirements

• arch doc

  • camera switching capability on Pegasus

  • smart audio if possible!

• ardupilot forums are a good resource too

Autonomy

LTE Comms

• Haven’t made a choice on which image compression format we want to use

  • Have a couple more tickets where we want to profile different image compression formats

  • We have an influx in new members so we can assign those tickets out

• Going to start creating the repository to transmit images over LTE

  • Will create it so that the image compression format can be added as a module so we are not blocked

Aiming for the 10th to FT

admin

• Going to start assigning directories to team members to clean

Mech

ELRS RX (TCXO)

• will be sticky tacked on final drone

  • subject to change depending on antenna placement

Electrical

RFD900x harnessing

• RFD900x has been broken for a while now, which is painful to debug.

• Decided to make a breakout PCB to interface with locking JST connectors.

• Yuchen is slaying on the breakout PCB, @Daniel Puratich will review

• Will be RFC’d into sys arch once tested. (right?)

~ a week until completion. 2 weeks to ship, 3 weeks from now receive the board.

EFS

ELRS Gemini status

Assigned Akam to this task. He aims to start work on 23 Jan 2023

ELRS / ardupilot channel mapping

• To be updated when able (likely during reading week downtime)

• also some model ID management. Model match to manage all drones.

Side notes - during ~ 3 weeks of reading week downtime. not urgent

• more content in device manuals, etc

• configuring competition controller settings

• increasing telemetry rates

Autonomy

LTE @ FT

• No progress on looking into what happened with LTE on the flight test

  • Need to delegate to someone onsite

  • LTE telemetry disconnected (RPi froze over.. ?)

    • No failsafe was triggered, Ardupilot did not detect loss of GCS connection

GeoLocation

• Working on getting Geolocation tested

  • We have someone actively working on blocking PR

Mech

Airframe Timeline:

Current due dates for tasks (I’m not gonna read all of these but they are here for visibility):

• Rev 1 Cabin - to be mounted on pegasus 1.0 by Feb 3rd, best case mounted by Jan 27th

• Pegasus 2.0 - Assembled by Feb 3rd, possibly Feb 10 (depends on machining time)

• Rev 2 Cabin - mounted on pegasus (unsure if 1.0 or 2.0) by Feb 17 or 24th

• Landing gear improvements - to be done Feb 17th

• Waterproofing - to be done by end of Feb

Houston

• Rpi + 200 CV camera needs to come off (payload)

  • happening this week

• rangefinder needs to be tacked + ziptied on

Electrical

Houston power

raspberry pi harness was made from last term, it was supposed to improve the raspberry pi input voltage, not tested its performance yet, will test it Tuesday, Jan 23rd (or sometime later this week)

telemetry fwd’ing

decide how information is getting from GS to antenna - xbees, ELRS airport, cables?

• make sure we have enough of these/ know how to use it
