Thanks Nate for your suggestions. This message might clear some things up.

I was not the one who decided to use the pic. It was my partner's idea.
I will tell him about your ideas. As for why not use robostix, there's
three reasons behind it. First, we're in Canada, so customs always burn
us a bit when we're getting technical equipment from the U.S. Second, we
have pics currently at hand to work on and my friend has more experience
with it than the robostix. Third, we just plainly don't know about it.
Other things in concern, but are not main reasons, are size and power

I am actually thinking of the same idea, but it seems like my partner
believes that the LCD is going to use up all of the GPIOs (I doubt it
personally though, and since we haven't got the LCD yet I really doubt his
assumption). I will have to talk to my partner more on this issue.

Hmmm... If I'm not mistaken, isn't the Hirose already used to connect to
the breakout-gs board?
Thanks for your suggestions. I will talk to my partner and send an update
as soon as possible.
