I've got a small robot that can wander around looking for metallic objects. The
tires that I have on hand which work best on the carpet I have at home are
these:

I'm also stuck on a strategy to figure out the heaviest can. One idea was to
build a 2-side ramp platform with a see-saw balance in the middle, but a
prototype showed that design to be flawed. And maybe as likely to pick up
another robot as a can. Another idea is more brute force -- a tall platform with
a gripper in the middle. I don't know how many magnets you need to pick up 1 kg
(I only have 12 on hand), but I've noticed that when a bunch of magnets are in
swivel holders near each other, they tend to orientate themselves in an
unhelpful direction.
