I was in FIRST in high school and now serve as a mentor, one of things that sparked my interest in Electrical Engineering was taking apart different things. As a student I do recommend wikipedia and yes there are several kits out there that can teach you the electrical side. If you want to combine that with a robot there are examples such as:

TekBots (eecs.oregonstate.edu)
BoEBot (Parallax.com)

and I would also recommand looking for introduction to electrical engineering classes at colleges around the country, having toured places like MIT and CMU they have many online resources where you can look at whats taught to first term students at those places. Of course I recommand TekBots because its at my school, but many colleges have simple kits that come with a breadboard or a pcb (printed circuit board) which introduce to those components mentioned by the others. Specifically in the vex brain there are two microcontrollers from microchip which is a leader in the microcontroller market, I would also look up this on wiki.

Hope you get inspired by Electrical Engineering like I did
