Building a Robot for class! Need IDEAS!

We're building a simple robot for our electrical engineering class at Berkeley. The only thing it MUST be able to do is stop when it senses a wall (via light sensors) and then back up and turn.

It runs on two-tank like treads and has the circuit board built on top (picture included). It has a serial connection for connecting it to a computer or any other sort of input device.

It has NO limitations on what we want it to do (except we can't do anything destructive. :( ). We can make it remote controlled, climb stairs, travel in water, anything! Anyways, my partner and I were looking for original ideas of what we want it to do. We were thinking of maybe making it a hovercraft (via some high-output 120mm fans). Is it possible? We also think it'd be cool if we made it climb stairs.

Getting ahold of additional electrical parts (sensors, LED's, logic processors, etc) isn't much of a problem since my dad works for an electrical engineering company.

Anyways- give me some of your original ideas! Nothing destructive please! And remember- we're limited by the hardware and $$$, so nothing like strapping on a jet engine and making it fly.

It's being controlled by a 50 Mhz C167CR (16 bit CMOS single-chip microcontroller), has 32 kb RAM and 64 kb flash.

Best robot gets automatic full credit on hw's and a nice digital camera!

that's an awesome assignment!!!

hmm.. some ideas, include, a small camera, maybe like a disposable camera, that will take pictures of spots normal people can't get to.

that's about all i can come up with right now.. hmm... creative mind is dead right now.

I know Cornell had some soccer playing robots. But I guess your thing is pretty slow.
How about making something that can follow a path, like a chalk line on asphalt, like these guys

Whoa! A little bigger than I was planning Anarchos. :D But we have three months to finish this robot . . . so maaaaybe.

I'm an Engineer involved with the same competition as Anarchos. Below is a picture of our robot from a few days ago. It's changed a bit since then, but not much.

As a reference, you have 3 months for your project, we have 6 weeks.

I thought it might be cool to put one of those wireless cameras on the front. The company I work for does a similar thing, but it's all tethered, and our products are a bit more "finished". I also thought a hovercraft might be very cool, but I don't think batteries have a high enough energy density to lift the device.

The hovercraft thing would be cool. If that wouldn't work, though, it would still be cool to have it be amphibious. How about also turning it into one of those fan-boat things they have down in the swamplands? You know, the kind they take tourists on to look for alligators. You could control the speed and direction of the fan via remote.

I guess that would really just be kind of a remote-controlled boat/tank, but I still think it would be cool. :) Put a clear bottom on it, throw some Lego guys in there with a miniature six-pack holding a fishing pole. :)

I wish i could get into a robotics class/competition. Robot's have alsways intrigued me, if I had time, I might build something on my own.

But carpe, I once built a robot that could detect metal on the floor, it was kind of a change finder. Still have it, it had nice wall detection, it would rotate to do a search pattern, it was simply made with a few transisitor's and relays.

I have a thread some where on the forums, for any one to try to build a device to launch cd's (think of those stack of aol cd's) so that you could use the aol cd's as target's i.e. a skeet launcher. maybe you could rig it with a reflection sensor, and build like one thing to launch cd's lightly, then have the robot search the floor and bring them back.
