When I search about robotics, lots of stuff comes up, what never comes up is the robots actual design, and by that I dont even mean how cute or stylish it looks, I mean the actual structure design.
I have special interest in know how they come up with the best joints for the best task, like "oh, i need x degrees of freedom here, but it needs to support y weight, so since Im limited to materials s and z, I think joint j will do the work".
Is it mechanical engineering? is it industrial design? is it not really present in a single field? I mean, robotics is pretty generic and deals with a million of different stuff.
So, say a team is making a robot, say something like big dog, how/when exactly the joints gets decided..?
Say I want a biped robot capable of walking trough rough loose rock terrain, how do I decide the best kinda of legs..I know these answer are not simple (theres not even a robot capable of that, for what I know), I just have no idea what fields of study deals with those.
