Safety

Protects People, prevents drone linear movement

Minimum angular resistance

Minimize friction/moment of inertia to tune PIDs as closely to flight as possible.

Fastens to both the pitch and roll axes of the drone as close to the Center of Gravity as possible.

Connects securely to the drone in 2 alignments 90 degrees apart

Approximately rotating around the C.o.G

 Assumptions

  • The rig will be used for only quadcopter PID tuning for (only) pitch and roll

Drone will have only 1 rotational D.o.F

Only Pitch OR Roll will be tuned at once.

Drone will be secured so that it cannot move linearly.

Don’t want drone flying away

HIGH MEDIUMLOW

 @Conall Kingshott

 

Heavy enough (or can be secured) such that multiple sizes of drone can be secured operating at full throttle

Don’t want drone flying away

@Conall Kingshott

The initial revision will only be compatible with Phoenix as a proof of concept before scaling up for other drones.

Safe way to inject a force on a set of props

Point of tuning is to test stability of drone when subject to external forces

Where will this be used?

  • the bay

  • outside

  • basements of members houses?

How will the drone be controlled from a safe distance?

  • long cables with quick power disconnect near the user

  • RC-controller or zp w/ kill button

What barriers are between the props and any humans?

  • theoretically, prop guards + blast shield style screen

Will we be doing one rig per drone or one rig per all drones

  • For the first revision at least, there will be one rig exclusively for Phoenix

  • A more universal setup will be investigated after the initial design is tested

manufacturing cost limit?

  • Target is <$30 (As set by Conall)

 Out of Scope

  • Yaw tuning

  • rig that allows drone to move freely within constrained space
