Using 1x1's wouldn't permit you to build overhangs or under-cuts.
But also, using things that big as the smallest building blocks would
result in very coarse-looking objects. You also need a heck of a lot
of them to build a solid 3D object of any size. To build just a 10x10x10
stud cube, you need 100 of them for each layer and about 22 layers - so you'd
need 2200 1x1 plates. But then look at building a Lego sculpture or something.
You don't have the resolution to make a believable looking sculpture in
just 10x10x10 studs!
No - these machines have to be able to build *anything* that you could
describe with geometry in a computer. I have seen one of these machines
building a ship in a bottle by building up both the ship and the bottle
layer by layer.
Here are some links to the machines I'm thinking about:

I understand that I'm not going to have that much resolution using Lego - but
even producing something fairly lumpy would be impressive.

| (...) I've had a 3D graphing calculator on my mind for a long time. Another of my hobbies is 3D fractals. In the case of the 3D fractals I would make, there would be no overhangs. Imagine though that you did not restrict yourself to 1x1 plates. What (...) (20 years ago, 12-Mar-04, to lugnet.robotics)

| Hi Steve, (...) how about building a robot that uses a pile of 1x1 plates as raw material? These are even easy to come by in the form of mosaics. Jürgen (20 years ago, 12-Mar-04, to lugnet.robotics)
