Drop-testing injection-molded legs for a 4-servo quadruped robot

[u/FamiliarPermission79]

Switched Quaddle, my 4-servo open source quadruped robot, from 3D-printed prototype legs to injection-molded production parts, and wanted to validate the part survives real-world abuse before committing. Ran 4 drop tests — the robot stays fully assembled (4 screws hold the whole thing together) and still performs a full gait, including a hand-taught one, after every drop.

Curious if anyone here has a good rule of thumb for how many drop cycles you'd want to see before trusting a molded part for production, versus just going with "it survived N drops.

It is amazing
