[DPRG] Evolved mechanics

Found this on another robotics mailing list. 

This researcher evolved a bunch of walking creatures and created them
out of pvc.  He uses fins as sails to absorb energy, bottles to store
energy as air pressure and a vacuum system for simple logic.  He has
sensors to detect water and an approaching storm.  He is evolving them
(in simulation, I believe) to survive on a beach.  He builds life size
models as proof-of-concept.

Here's a video:

Yes, generally.  But, it took 40 years or more for flat screen TVs to
appear, and I'm still waiting for my personal jetpack.

Haha!  You got me there...while I agree that Subsumption may be old
hat, it's still a good hat.

I see that it's available used on Amazon for about $11.00.  I think
I'll order a copy based on your recommendation!

I think that's true for the majority of robot hobbyists, myself
included, unfortunately.  A few of us are doing incredible work,
though, which keeps me hopeful.

Well, Brian beat me to it. First, there's a trend away from
Subsumption, with its rather bizarre restricitions, and Jones,
Arkin and Murphy talk about Behavior Based Robotics. Then Arkin
and Murphy talk about Hybrid Architecture.
