Testing Drone Requirements

Firmware is able to perform extensive testing with this airframe at any time

Number of testing delays due to missing hardware (Lower is better)

Crashes and failures result in low time and monetary cost

ESCs shall be DSHOT capable

Firmware has a DSHOT implementation that should be tested

MID

@Anthony Luo

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

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

 HIGH

@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.

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

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

LOW

@Dhruv Upadhyay

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

HIGH

@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

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

MID

@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)

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

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

LOW

@Gordon Fountain (Deactivated)

What will ZP3’s dimensions and mounting dimensions be?

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

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

MID

@Andy Meng

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

MID

@Anthony Luo

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

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

need to be able to mount imu securely

MID

@Anthony Luo

What IMU will be used for testing?

The drone shall have a minimum 5 minute flight time

We want to fly for enough time to perform tests

LOW

@Sahil Kale

What will ZP3’s dimensions and mounting dimensions be?

What is the maximum allocated budget for this project, including the frame and the electronics?

$175 per drone, subject to revision.

What IMU will be used for testing?

Increase in total budget? (Link to total cost: https://docs.google.com/spreadsheets/d/13iCYi8xt17llvUCeuPL6VaMH38weA4_1ZqrnDxVHeCs/edit?usp=sharing
