[Robotgroup] Alrighty now from scratch

[Gray Mack]

Putting it all together... These are tough questions that robot builders face.
Each item you add adds to the cost and to the time for learning and writing code and the power requirements.
This takes a lot of googleing to figure out exactly what you want and what will work together.
I recommend making a spreadsheet of the items you find of interest, price, power requirements, interface type, etc.
Then maybe someone in the group will have had good or bad experience with some of these to comment on or might catch an interface problem you missed.
Some examples:
Sparkfun.com sells a bluetooth part that connects like a serial port and may be able to easily replace a serial connection. Parallax sells a serial LCD screen, its overpriced, but you have to make a choice of whether the price is worth the ease of programming versus a less expensive-more complicated 4bit interface that uses more pins on your processor. There are a number of companies that sell servo based grippers, but depending on the application you may need to make something custom for example to pick up ping pong balls or soda cans or legos. And it might end up not looking like a gripper at all, maybe a scooper or rotating brush could be a better fit for a given application. In any case dont give up on the boe-bot unless its too big or small, you could end up adding all this kind of stuff onto its platform somehow.

My goal is a robot with a griper to hold items, has communication through
blue-tooth, that line follows(using IRs[like my boe-bot) to deliver items to
"stations" so my first thing to do was get robot that could go forward,
back, left, and right. Also maybe a LCD screen.

What exactly do you want to build?  You should pick up issue 6 of Make 

http://www.amazon.com/Make-Technology-Your-
Time/dp/0596527179/sr=8-4/qid=1166052212/ref=pd_bbs_4/104-3533911-9582302?ie
=UTF8&s=books

They have a nice little writeup on some simple bots that absorb solar
energy and spin or roll around when they're fully charged.
