• 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

• Alison Thompson Evan Janakievski Georgia Vachon 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

• 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 Vachon 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 Nolan Haines

• No updates

• Michael Botros Mena Azab Nolan Haines Anthony Zhelnakov

• Will be worked on after exams.

• Mena Azab

• 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

• Currently working on mounting electrical components

• Reminder if anything has changed on EE side to update: Tracking Antenna Mechanical Tasks and Electrical Components

• Currently using the following servos:

  • PitchYaw: https://www.servocity.com/2000hs-series-dual785hb-mode-servo-25-2/

  • Image Added

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

    • Options:

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

        • aka direct drive

        • torque calculations for correct speed

        • Conall Kingshott Mentioned balancing issues in the Discord today?

      • Image Added

      • We could use a gearbox:

        Will possibly need a programmer for continuous:

      • Not sure which servo to choose. Depends on decision: https://www.servocity.com/servos-accessories/

    Yaw

  • Image Added

    • Will possibly need a programmer for continuous: https://www.servocity.com/3102-series-dual-mode-servo-programmer-1-1/Will need a continuous

      • not needed if we stick with 105 deg

    • May need continuous with current pitch servo: https://geargenerator.com/#200,200,100,6,0,0,0,2,1,16,0.8,20,14.5,0,0,0,0,0,0,0,46,2.3,20,14.5,0,0,0,0,0,0,1,3,334

      • What angle range should we plan for?

        • Currently 105 degrees.

        • Should be fine, because we have yaw anything more than 90 is useless

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

  • Is able to find north with +/- 10 Degrees inaccuracy

  • Used new library: https://github.com/drcpattison/BMX160

• 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 unsure of status.

• 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

    Pegasus Autotune

    autotune cannot be run in doors, too much space

    • 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?
