Hi all, I’m curious to hear the various ways your team removes weight; from “swiss cheesing” to the various ways your team may preemptively plan your robots final weight and everything in between! I would love to hear your story or any anecdotes you may have!
I would also like to throw out a few of my own questions to other teams when it comes to strategies for weight reduction just to get the conversation going.
Does your team do any structural analysis in CAD to see where you could possibly remove weight (i.e non-structural components) while retaining most of the structural integrity?
- When designing parts you plan to mill pockets into, do you use specific designs like isogrid, orthogrid, or something in between?
- What FEA/FEM software do you use or recommend? (Maybe something like SIMSCALE?) I know Autodesk Inventor has something for this (I haven’t personally played around with that quite yet)
Does your team have or take into account a certain factor of safety when building your mechanism so that you don’t go overboard on the amount of material that’s needed to complete a certain application/ task given the amount of strain/stress it might encounter?
What parts of your robot do you usually remove most of the material from?
Did your team ever dare suggest removing the cool LED lights from your robot just to save on weight?
- Aesthetic pieces (LED panels, etc)
