I've seen a lot of people talk about build quality like some mysterious concept. I think a discussion of build quality could really help some newer teams avoid some mistakes and give more experienced teams a quick reference and reminder.
What is good build quality to you? What makes a robot better built than the rest? Tips and tricks?
Compiled list of everything I've seen so far.
- Accurate spacing on axles - tight to reduce slop, not to tight to avoid extra friction
- Pieces of metal line up - keep everything square, avoid slightly bending metal
- Bearings, Bearings, Bearings!
- Using screws as axles wherever possible - drastically reduces slop and increases joint strength.
- Nylock nuts. Especially on bearings and gear attachments - reduces impact of vibration
- Loctite blue everywhere - prevents screws from backing out from vibration
- Use two bearings on axles - reduce slop
- get the nice setscrews and use Loctite in shaft collars - stronger hold, won't loosen as easily.
