I only recently became interested in robotics. I just built the 50 dollar robot and I've done alot of reading and I'm pretty much hooked, thinking of switching my university major from math to computer or electrical engineering. I've seen these iSobots on sale now for 60 and 70 dollars. Seems like a great deal, all kinds of hardware and a good well thought out chassis. Would it be a bad idea for a newb like myself to purchase one of these and try to proceed continue learning about robots through modding the thing? I'm taking classes in c programming and fortran right now and I'm pretty handy overall, if I do lots of reading/research is this a viable project for me to buy, and start modding in a relatively short timeframe?
