Advice on BSc Final Year Project

I am currently in the final year of my Computer Science Degree, and for the dissertation as I am study Computer Vision as one of my modules I was considering a project which involved a robot which could locate and track objects. I believe though that this may be too simplistic for the course so I was wondering if anyone here could offer me some advice on the matter, as it would be very much appreciated. I'd have to site you as a source of reference as all such things have to be included in the project bibliography.  

Is the POP-BOT arduino microchip compatible with the BOE-BOT developer board?

I have an Inex POP-BOT which came with an arduino-like microchip, and was thinking of getting a BOE-BOT, which uses a Board of Education with a BASIC stamp microchip attached to it. Now my question is, there two chips seem to look identical in size, and can both be detached from their respective developer boards, so what I'm wondering is, would they be interchangeable?

My First Robot

This is my first robot. It uses a POP-168 power board (which is based off a arduino ATmega 168). It uses two DC motors for movement, and a parallax standard servo motor with a sharp IR sensor mounted on it for object detection.

Advice on my next robotics project.

Hmm, I decided to come here on the off chance some one might be able to give me some advice.

I wouldn't say I'm an "absolute" beginner as I do have some experience with robotics, but its only been from kits, I haven't built and programmed something from scratch yet. Over the years I have collecteda great deal of items which I feel may be useful to create some form of robot, but its hard to know exactly where to start. Here are the details as follows:
