Base sizing of a robotic arm for maximum stability

[Aaron Mac]

I was going to consider both case. You think an advanced fea simulation is the way to go?

First figure out why you may wish to choose one base over another. If you aren't bolting it down then the base needs massive enough (and/or with some footprint) so the robot doesn't tip during its maneuvers. You can solve that problem with Dynamics. If you want a lighter weight solution that doesn't need to be "moved" you can focus on designing the bracket, bolts, and substrate.
