ESCs shall be DSHOT capable

Firmware has a DSHOT implementation that should be tested

Anthony Luo

DSHOT is generally more responsive, accurate and easier to use than PWM motors, but also more expensive.

yes

No part shall take a single person more than 30 min to replace

 Testing drone is expected to crash and hard to replace parts will delay fixing

Anthony Luo

For example: make arms replaceable with one or two screws, don’t mount legs to arms if possible, attach connects between pdb and escs, etc.

yes

Propellers shall be protected in case of a crash

Doing so avoids the cost and time of replacing props every time the drone crashes

depending on design it may not be feasible to do an entire roll cage, but for props bigger than 6” something to prevent prop strikes is ideal

soft yes: action items:

• Provide 3D models of prop guards to first years for streamlining, if there is interest Megan Spee

• Run the motor for 5 minutes with prop guard installed to test if overheating is an issue using a battery

• Print more w/ REMOVABLE rafts 🫵

• Add model to main phoenix assembly Megan Spee

Aircraft shall be able to survive a drop from at least one meter in a normal landing orientation

The first point to impact the ground during a straight drop need to be able to survive the fall

Dhruv Upadhyay

Reconsider requirement bounds - “good enough”

look into scotch weld, reference Conall Kingshott

A method to harness the drone must exist

while testing, it may be unsafe or otherwise unfeasible to let the drone free-fly and it needs structurally sound points to attach tethers or joints to limit movement to certain axes

Anthony Luo

in a worst case scenario imagine that the drone is dropped 2 meters and is jolted to a stop by the attachment points. ideally nothing breaks

Yes, with strings. Flyaway string can attach

PID action items to make phoenix compatible:

• Adding array of holes to each side of phoenix for pitch/roll PID, yaw attachment good enough Megan Spee

The airframe shall be as small as possible while being able to facilitate zp

smaller allows the drone to survive harder crashes due to less momentum while also being cheaper and easier to fix once it breaks

Sahil Kale

Personally Andy recommends a frame based around 6~8 inch propellers and a target auw of under 1.5kg

(aim for prop size between 6” ~ 12” unless there is a signifcant reason to deviate outside of these guidelines which outweighs other concerns)

Yes

If problems in future just resize body

The frame must have a mechanism to mount ZP (or a Nucleo) securely

testing frame intends to fly with both zp2, nucleos, and zp3

Gordon Fountain (Deactivated)

What will ZP3’s dimensions and mounting dimensions be?

The nucleos used will probably be nucleo-f401re and nucleo-h743zi

Yes

Internal mounting works well enough

Battery must be swappable without disassembly or tools

should continuous testing happen with a set of batteries, they should be able to be swapped out as needed

Andy Meng

Yes

Protection must exist for critical electronics on all axis

ZP and expensive hardware needs to be protected in the case of a crash from any angle

Anthony Luo

perhaps put it in the middle of the frame if using a sandwich style design again

Yes

A mounting solution should exist for an imu which reduces vibrations traveling from the frame

need to be able to mount imu securely

Anthony Luo

What IMU will be used for testing?

Not really

We can use velcro, double sided yellow tape, rubber, any kind of vibration dampener - 2 screws for IMU, 2-4 for Nucleo, buy in bulk. Megan Spee to bring up at next mech meet

M3 bolt holes for ZP Daniel Puratich

The drone shall have a minimum 5 minute flight time

We want to fly for enough time to perform tests
