i like simulated evolution models. do you know any other fun/ cool ones? also can we talk about broader implications, for example, is it possible to create small robots in physical space which function similarly?

>> No.6341979

I love that Tunzelbots video: http://vimeo.com/85053197

As a CS person who has never worked with simulated evolution models, how would one get started making things like that?

There are many examples of physical robots using genetic algorithms, and they have nice results. (Physical objects always interact more than you want, computer simulations can only use interactions the designers predicted.)

I remember a robot that tracked and found objects (a simulation of hunting for food) using evolving visual processing. Two different strains developed because the environment was slightly different during day and night testing.

yes, check out the GOLEM project. Pic related was evolved in a simulator and partially built in a 3d printer.

Getting coefficient of friction realistic turns out to be a bitch, so that's why the robot is pictured on sand.

You can download the simulator here:
http://www.demo.cs.brandeis.edu/golem/

Some of the same people recently came out with this:
http://www.youtube.com/watch?v=z9ptOeByLA4

They have even built some simple soft robots too. They walk on sand paper(again getting friction right is a bitch) in an alternating pressure chamber.

Framsticks does much of the same things as tunzelbots, only more:

first you need to figure out how a creature succeeds/ fails e.g. how far the car can go in that car evolution game
and then you need to randomly generate creatures and combine the two ones that go furthest to make a new one that goes even further
