Subject: [alt-beam] 78 Neuron Robot
The original neural net was designed on a computer. A virtual "world" and a
virtual "bug" were created and it was tested for over 2 years. They proceded
into building a 1 Kg robot using the same neural network. I don't know if the
robot was hardware or soft ased, but they mentioned that they had to tune it for
it to work, whereas the computer sim didn't.
I'd make the hardware if i could get all the parts. I'd like to go a full
hardware route to prove that BEAM can do a very complex robot, and hopefuly go
for a record! Hehe! (:
I'd not hesitate to go with hardware, the problem is that every schematic of an
Nu neuron I've ever seen uses inputs from tactile sensors and has one output. I
simply assume the outputs spit to other inputs, but I have yet to see a diagram
of two inputs coming together. I also am not certain how one Nu can have both
inhibitory and excitatory inputs and outputs. I'd ask Tilden... AGAIN... but I
never get a reply. You know his address? He seems to have more than one. One,
little, tiny example and I'd be set! I'd start building this thing in a
heartbeat! There is no GOOD information on the interconnection of Nu and Nv
neurons. Also, the subject of multiple Excitatory and inhibitory signals realy
interests me. Obviously, biological neurons are going to have this in quantity,
but the curent Nu neurons in BEAM are either + or -, presumably excitatory or
inhibitory, respectively. I may look into op-amps, as I've seen some info allong
those lines, but I wonder how complex that'll be???
Who knows, well, maybe Tilden and those scientist guys! Hehe! (:
