Task Description
Design a carrying jig for Peggy 2 that is compatible with the new landing gear, payload, and bottom plate
Constraints
Constraints | Written By | Append Date |
|---|---|---|
New bottom plate will not have as many mounting holes, use the large holes underneath the arms as mounting areas. | 2024-11-07 | |
Two variations of payload that it would possibly need to be compatible with. | 2024-11-07 | |
Have the base have arms that can reach past the motors unlike Peggy 1 Jig | 2024-11-07 |

Inspiration
Use Peggy 1 Jig as inspiration for the new one, https://uwarg-docs.atlassian.net/wiki/x/FgD5jg
However, with the new landing gear and payload there will be a decent amount of changes.

Updates from Alison Thompson after 2024-11-14 meeting:
Remove cheese from plate
Add needed holes to avoid angled landing gear

Overall, looks good
The arms go past the motors which is good, there will be some awkwardness when the jig is angled, but this becomes too large if we think about the other angle and becomes tedious to take on and off
A couple things I forgot to mention but could be improved upon:
The holes for the where the jig holds onto the drone can be increased in size.
these were part of the drone before I made the first version and there have been issues when placing the drone on the jig
The countersunk holes can be taken away, they are a huge pain to machine and didn’t fully work as the 8 GA sheet isn’t thick enough
Use just standard M5s and the center bolt can be taken away
The bottom of the gussets can be trimmed to be equal with the boxtube, the oversized dimensions was to act as a support when sitting on the table/ground. However, we can get rid of this as adding tpu (or other 3d printer material) endcaps can be added
Ensure these endcaps are tall enough to go past the screw heads
Look at the endcaps on the arms for sizing to fit within the boxtube
The endcaps on the arms need to be rotated 180 degrees and can just be square, originally, I thought these would help with supporting the arms, but they don’t even touch the table half the time.
Ensure they cover sharp edges essentially

Notes from mech meeting 2024-11-21:
Just adjust the holes on the carbon fiber, just a couple millimeters extra
No gusset changes or other hole changes
Whichever boxtube was changed please mark down somewhere so we know what needs to be ordered

Please switch all the coincident mates you have for these parts to width mates so you can visualize how it would actually sit
You need to redo the distance between the holes, they should be inline with those hole clearances in the back of the screenshot
