2023-12-05 AEAC 2024 Sync

Introduction

  • @Daniel Puratich

  • @Darwin Clark

  • @Alison Thompson

  • @Anthony Luo

  • @Nathan Green

  • @Arjun Mandair

  • @Jerry Tian

  • @Mena Azab (Deactivated)

  • @Nathan Green

  • @Conall Kingshott

  • @Megan Spee

  • @Georgia Westerlund

  • @Yuchen Lin @Nathan Green

  • Completed auto-tune all axis

    • four batteries

    • logs in thread, should be linked in debrief

    • we didn't fly much after autotune so minimal changes

    • @Anthony Luo to analyze

  • @Daniel Puratich

  • Next deadline is phase one paper

  • No more AEAC syncs for this term!

Systems

  • @Conall Kingshott @Nathan Green @Jonathan Di Giorgio @Mena Azab (Deactivated)

  • Slight redesign on clamping blocks

    • had one cracked a little, not major

  • Wires rerouted to give extra length

    • very cool!

  • No other updates

  • @Alison Thompson @Evan Janakievski @Georgia Westerlund

  • No real updates here

  • getting inside layout figured out and waiting for panels to be cut

    • may need to follow up with Graeme on this

  • @Andy Zhang @Conall Kingshott @Alison Thompson

  • CA glue in I think

  • Waiting to glue onto clips.

  • Gonna do that after clamping block mods.

  • @Smile Khatri @Mena Azab (Deactivated)

  • Clevis pin

    • funny looking bendy one

    • they don’t make smaller ones with same diameter

    • won’t accomplish goal of less play/give by using a smaller one, would make it worse bc 3d printed part

      • could do a reccess in dovetail?

      • might not be worth effort

  • Cotter pin

    • the straight one with the hole in it

    • This is already the smallest one they have on

  • @Nathan Green @Georgia Westerlund @Megan Spee

  • No updates.

  • @Nathan Green @Alison Thompson

  • LiDAR mount exists for Houston and is ready to go

    • needs to be test fit but should be fine

    • M2.5 bolt to drone, M4 on LiDAR

  • @Tom Chiu

  • On hold till after exams

  • @Michael Botros @Mena Azab (Deactivated) @Nolan Haines

  • No updates

  • @Michael Botros @Mena Azab (Deactivated) @Nolan Haines @Anthony Zhelnakov

  • Will be worked on after exams.

  • @Mena Azab (Deactivated)

  • No updates other than rerouting the ESC wires.

  • Ordered and received more 16awg.

  • @Nathan Green @Conall Kingshott

  • Worried about the M4 solution

    • M4 was originally decided for the motor mount bolts

    • It’s tough to prove board will be okay without testing in place

  • @Neel Patel @Parker Lawrence-Valeriani

  • Switch XT30 to solder pads for more clearance

  • 3mm clearance on back of board

  • Do two boards

    • One the M4 for motor mounts

    • Other with M3s

      • Then mount with heat-sets

  • Hardware: @Farris Matar @Daniel Puratich @Anthony Luo

  • Firmware: @Derek Tang @Anthony Luo

  • Three boards assembled

    • Two have been tested thus far

  • There is a test plan in discord from Anni

    • early next term possibly flying it

  • Plan

    • Gemini to Gemini

      • easier to test in this configuration

    • Gemini to two diversity receiver

      • more common online

    • Getting a lot of radios on drone

  • @Arjun Mandair @Conall Kingshott @Nathan Green

  • Currently working on mounting electrical components

  • Reminder if anything has changed on EE side to update: Tracking Antenna Status & Mechanical/Electrical Components

  • Currently using the following servos:

    • Yaw: https://www.servocity.com/hs-785hb-servo/

    •  

      • Will need a second yaw servo since current yaw servo gearbox is discontinued on ServoCity

      • Options:

        • We could use a Servo Hub: https://www.servocity.com/servo-hubs/

          • aka direct drive

          • torque calculations for correct speed

          • @Conall Kingshott Mentioned balancing issues in the Discord today?

        •  

        • We could use a gearbox: https://www.servocity.com/servo-gearboxes/

      •  

    • Pitch: https://www.servocity.com/2000-series-dual-mode-servo-25-2/

  • @Nolan Haines @Hardy Yu @Michael Botros

  • Schematic is basically done

  • in process of being reviewed

    • lots of points in it currently

@Yuchen Lin @Stanley Tang @Ayoung Eun @Aryan Kashem

  • IMU sensor fusion complete - track antenna rotation + know which direction is North

  • Configured XBee to communicate

  • Still need to connect XBee with Arduino

  • Should prepare to use mini pix or COTS solutions

    • something with just integration time

    • fairly isolated task

    • need to start on backup plan

    • currently it is mechanically working 3d printed in bay

  • @Alex Yang @Amy Hu @Mihir Gupta

  • No updates. @R D (Deactivated) unsure of status.

  • @Tong Zhang @Amy Hu @Mihir Gupta @Nathan Green

  • We hooked up the Jetson with the ZeroTier network and we can read drone telemetry from the Jetson.

  • We are working towards sending images to the drone which we will finish in the next term. Right now we are profiling different image encodings to see which is the best one to use.

    • We will be using a lot of data for this?

      • 6 gb of data is 30 mins of 1 img per sec

        • just pngs right now

        • looking into different encoding specs

    • change code to only transmit images when landing pad is spotted

      • could reduce usage time a lot

      • system is not setup for that right now

      • could be on a communication between pixhawk and RPi to tell it when to start looking for pads

      • the RPi can already read MAVLINK telemetry

      • simple solutions plz

        • excessively transmitting to gnd is kinda hard …

      • this is possible

  • @Arunav Munjal @Amy Hu

  • Task 2 code working on mission planner and realflight simulator

    • USB test had some issues so will be looking into fixing that

      • connect usb from ground station to pixhawk directly

    • Define new “Location” class in common repository first

      • infra thing

Admin

  • @Hardy Yu @Yuchen Lin @Anthony Luo @Daniel Puratich

  • Remaining Testing Goals before end of term

    • Ground Testing

      • Gemini

      • Video over LTE

      • Calibrate Optical Flow

      • Monster mount offsets

        • for rangefinder and Optical Flow

      • Tracking Antenna

    • Flight Testing

      • Pegasus Four Battery Endurance

        • Autotune required

      • Pegasus Six Battery Endurance

        • We do not have enough nice batteries for this

  • Save more testing plans for next term?

  • @Georgia Westerlund

  • Phase #1 Paper Link

  • Official Deadline: mid January (see gcal)

  • Please ping leads if you do not have editing permissions

  • Do not copy paste AI into AEAC paper

    • @Daniel Puratich trolled this morning

    • mfw initiating the super long AI conversations go brrr
