PSpice is pretty much the standard for the general circuits needed for a FIRST robot. If you're looking for circuit board design, EAGLE is a great program. And finally, if you're looking to do programmable logic, MAX+PLUS II is good. All three have free *limitted* student versions.

I have pspice student(awesome program), but am looking for something with larger component libraries,(or just some more pspice libraries). I'll have to take a look @ eagle, as i have also been lookign for a board layout tool. I'll also have to check out MAX+PLUS II

If you are refering to laying out a PCB board. I've used PCB123 and PCBExpress (or maybe it's ExpressPCB, I can't remember). They both have websites and free PCB layout software. The idea is you use their software for free and then pay for their boards.

Hope this helps.

PCBEXpress is great except for one small problem. If you either try to print your design or export it to an image, it puts a grid of dots everywhere, so you can't use it to make your own boards. They want you to order from them.
