Re: Robotic iguanodon ref.
Oh, if only I could be on the team working on that, it would be incredible,
I've got a great deal of skills and designs that would be perfect for such an
exhibit, as that's what I've been working towards doing for at least a third
of my life.. (As many of you may remember, I once or twice have sent
off-topic mail, detailing my own similar group doing just these things, and
now look at this!)
Anyone know if they're going to be keeping public contacts on this project?
I'd love to be on some sort of news list, electronic or otherwise, detailing
this incredible event, as well as providing a design journal.
Just now, I can suggest one thing, if anyone was to be paying attention to me
at this point, but, as few probably are, I'll just say it anyway. With the
problem with the batteries' life being a limit of an hour, if they were to
have the robot feed from plants, either fakes in displays, or potted plants
in the hall, perhaps they could set up recharging stations at each, as long
as they somehow avoided the problem of battery-recharge memory
imprints(either finding a non-imprint battery or replacing them every week or
so), they could create a thing that, as the iguanadon's snout was buried in
the plants, it could grab a device that would fit into it's jaw, that would
connect with contact points inside the mouth, probably on the roof, or both
on the roof and under the tongue, and for the time it was browsing, it would
briefly recharge long enough to make it to the next nearest plant/recharge
device, including enough time to move around different obstacles. The
jaw-piece could even be like a sports retainer, and be on a cord, allowing
the creature to 'browse' around the plant.
If anyone's gotten this far and has expertise in the field of robotics,
please, critique my concept, or, if anyone from that robot design team
happens to be on this list, please, tell me your opinion. This is not meant
to be misplaced information, it seems on-topic enough.
