Modular Building Systems

I'd go as much versaframe as possible and use the 1:1 drawing on paper-glue-drill press method of making any gussets that need to be different and accurate.

I'd also highly recommend getting either a scroll saw or a bandsaw to help make anything more custom/ irregular.

Try to CAD the robot before you build it to make sure that everything lines up before you build it (IMO, CAD is pointless unless you use it to design your robot. If you build before you CAD, there's no reason to CAD because it's not influencing anything).

I'd avoid tetrix because of the cost if possible. Same reason I'd use wood (it really does work well for most things).

The best robots in FIRST are rarely the ones that are crazy complex, try to make a simple robot within your means.

Even if you think you can't handle it, get a mill and learn how to use it. They are invaluable for making things in precise locations; you could make your own versatubing if you get anything with more than 12" of table movement. There are plenty of videos online about operating one.
