Well, I've gotten my first version of the RetrievalBot complete. It's a track-chassis Roverbot (one of the basics in the Lego Mindstorms Constructopedia) with a single bumper on the back, and a homebrew odd spring-ish arm.

Pics: (all images are 800x600, hence just links)

Side view, with the retrieval arm fully up. It can continue another 90 degrees forward to pin an object. (Hand, shirt, and pants belong to my father.)

Last pic: front view of the robot, arm up. The hand in the image supporting the arm is mine.

And yes, the robot's arm is able to move on its own; it just hasn't been programmed yet, hence is off, and therefore is not powering the motor.

So... the arm comes down behind a present and the bot drags it out?

I have to say, that's quite possibly the most complicated way of doing it I can imagine. I use the pentactyl attachments to the ends of my forelimbs, commonly known as 'hands' ;)

Behind or on top, yes. I've actually had to redo most of the arm arrangement already, as it tended to pull itself apart as expected; I had to set it up using two 3x1 boards with holes and a z24 gear with holes, and two extended black pins- it works better that way.

And hands just aren't as much fun. But if you want "complicated," get a Rube Goldberg machine.

Pity that most Rube Goldberg machines involve things that aren't as likely to stay put, though- such as something involving a fishbowl and an irritable bulldog, that sort of thing. Otherwise I'd have them all over the house. :)
