  IR camera?
 
I'm not sure how feasible this would be, but has anyone considered making a digital camera using the light sensor? All you'd need is a focusing mechanism with lenses/mirrors, and a couple of motors to scan left to right and up and down. Sounds easy (...) (26 years ago, 9-Feb-99, to lugnet.robotics)

  Re: IR camera?
 
(...) I nominate a Lego "assembler" as an "ultimate" project for a RCX (or more likely a group of RCXes with a PC). I've seen a few Lego brick sorters, an assembler seems like a logical next step. Once you have all those bricks programmatically (...) (26 years ago, 10-Feb-99, to lugnet.robotics)

Try putting some bricks together using your knuckles - that is with pressure feedback, now try doing it in a dark room :) It's a cute idea but I think you'd have *real* trouble with anything smaller than 2x2 bricks, or is that what you meant?

  Re: IR camera?
 
Hi, yes, I actually had the same idea: use the light sensor on a robot as a crude mobile low-quality camera, which sends back scan-lines to the PC via datalog. however, thinking about the needed IR transmission and the line-of-sight precondition (...) (26 years ago, 11-Feb-99, to lugnet.robotics)

(...) I'm not an AI expert, so correct me if I'm wrong. To evolve, you need a purpose and some means to give it a score how it performs in real life. It would evolve into what? It needs a purpose. And why should it evolve in the first place? How (...) (26 years ago, 12-Feb-99, to lugnet.robotics)

(...) I think all the above are legitimate problems. I was talking to some friends about this the other day. One major problem is the fact that sturdy robots or other similar constructions are usually made up through cross-bracing. To put together a (...) (26 years ago, 12-Feb-99, to lugnet.robotics)

(...) You're wrong :-> (...) All that is needed for evolution is variation and selection. Variation with in the 'genes' of the population would be the instructions to build each. Selection would be some method that would mark the 'unfit', so that (...) (26 years ago, 12-Feb-99, to lugnet.robotics)

  Genetic programming (was "Re: IR camera?")

(...) True. However, in your case, you'd have evolved altruism. Still, the point was that 'purpose' is a perception overlaid on the system by humans. (26 years ago, 15-Feb-99, to lugnet.robotics)
