3D Printing + The Robotic Gibbon!

Daphne from the TRUCE project has ordered the MakerBot Replicator 2 printer for me!

I found the above, which is lovely, and I am going to have to learn to use TopMod and Meshlab to make STL files of 3D shapes for the "Living Light" project with Alex, Sumaiya and maybe (hopefully) Max.

After dinner last night, it was clear that the lamp must be able to exhibit attention in interaction so might need one motor degree of freedom, and should have something like eyes, and shouldn't look like a lamp because it is much more than a lamp, but should look like an alien form, like Haeckel's paintings, e.g.


The question is, how to get such paintings into 3D forms? Its going to be hard, but I think there should be an evolutionary story that can be told, e.g. the printer can print a set of core skeletons. Each one consisting of say 20 types of 'bone' that connect with each other bone in a set number of ways. These then can be evolved, and fit in together to make the exo- or endoskeleton of the lamp over which fabric,paper etc... are placed to form the light bearing surfaces.

Another method is to use a 3D body simulator to evolve morphologies that satisfy some function, and to then print these morphologies of-course, e.g. get the above haeckel developmental systems to arise, and evolve them direct in SLT files, e.g. Clune and Lipson. and the wonderful evolution of artefacts here. Looks like EvoShape is a company doing the same thing!

Just back from the zoo where I saw a fabulous swinging gibbon. Some robots like that below but no where near as impressive!

Robot Gibbon (Gibot)

Amazing idea of the Gibot. Love it. Download the original paper here, but its open-loop, not closed loop, and I can see the Gibbon is very closed loop, he decides exactly where to move by choice of hand holds etc... Its quite beautiful. Download Rosa et al's paper here. 

There is a WHOLE COURSE on brachiating (brachiation) machines here! 
Hod Lipson obviously did it first :) here. 

Northwestern has done it all! I like this Todd guy! See here for their Marionettes!
