finally catching up to robot tech, tough. Imho should have been from

Here is the
claw designdetail. I had originally a spinal motor driven mechanic in mind, but I
think that was also too big; same with normal claw mechanic. This one
is more compact and shouldn't break the mechanic because it doesn't
rely on true mechanics.
My thoughts on the
eye camera sensor. So called 5 channel multi spectral camera. Not really futuristic except the sensor design itself.
Some
further thoughts. Let's say it's a 2048x2048 pixel sensor, 5 visual
band, and 12 bit for each pixel => 20 Mega data packs a 64 bit or
160 MB per frame visual data throughput.
And that for each camera.
I had a max of 200 FPS in mind with energy saving for 25 FPS.
So that would be max. 3200 MB/s or 3.2 GB/s.
A lot but no problem with optical processing power running at 100 THz (old physics limits).
(Quantum data transfer limit is something new)
Edit:
This is not enough to compete with a flies reaction speed. For that 300 FPS are needed.
Comparison: bomb guidance 512x512 pixel a 8 bit and 400 PPS
Missiles are faster of course. Next gen is expected to be 1000x faster.
I guess real tech will make the cat look old.
I just feel like cranking some more numbers now to see how good my estimates have been.
Naro's brain:
It's an Abh computer crystal that is inserted into the head. The body has already the basic sensor and body control processing units. So it's like inserting the cortex part into the rest of the basic brain stem.
The crystal has a transparent protective layer against scratches and hits. It should withstand anything less than a hammer. If you know how violent small kids can be you know this is necessary.
I think the crystal is about 200 grams. Naro is as big as a Lynx after all!
So this is about 3.2*10^26
u.
Let's say 10^7 nuclei are used for each logic element and on surrounding structure and circuitry => 3.2*10^19
Let's say 1/4 are actual processing elements and 3/4 are working memory elements => 0.8*10^19 and 2.4*10^19
Let's say it's a 64 bit system for instructions and data, and 512 bit for math.
Basic clock runs at 100 THz. So max. data processing is at 25 Tera data packs of 64 bit.
2*4 Giga data packs go for visuals; 100 Giga data packs for audio (estimated); 100 Giga data packs for others ~= 250 Giga * 4 reserve processing power
So we got 24 Tera for AI verses 1 Tera for basics. Hmm, quite a good ratio.
This would give 96 Tera instructions per second available for AI. Needless to say this is too slow.
Parallelism is needed! We got 0.8*10^19 logic elements for processing.
Let's say 10^9 are used for each basic processing unit. Special units are squeezed in the margins and ignored.
So we got 0.8*10^10 parallel units. On top of that because this is an optical brain it can use different lights (beams) called channels. In short one brain with many brainwaves at the same time. 100 channels are possible, but this is a cheap civilian piece so 64 will do.
96*10^12 * 0.8*10^10 * 64 = 4915.2*10^22 instructions per second
That's roughly 20000 times faster than an estimated human brain.
(and people say that's not possible)
If each memory element is holographic storing data from all channels is not a problem.
This would give 2.4*10^19 * 64 bit or 192 EB of working memory. This is not enough to hold all the data processed each second, though. At least 707788.8 EB would be needed.(I guess)
Naro's databanks:
Well, similar to star trek TNG chip-pads (or whatever they are called) but somewhat bigger.
4 pieces in lower skull or back of mouth area; 8 pieces in breast area.
Each piece should be about 100 grams = 1.6*10^19 * 64 bit (like above arrangement?)
This gives at least a total of 1536 EB. Well, they should have higher storage efficiency than the crystal brain, so it could be a lot more.
Edit:
Using normal laser 400 channels are possible for holographic memory. Electron laser offer more but is uncertain if useable within such devices. Holographic can also store from different angles. Obviously reverse direction won't do, so angles are restricted to 0-90 degree. In 3D you got two additional vertical & side plane. So max. factor is: channel * angels * 3.
From a conservative point 256 channel and storing direction from front, one side, and top would offer an increase of 4*3=12 times. This would result in 18432 EB.
Enough to store all texts from all books, but no pictures or media. IMHO for media at least 10^4 more are needed (blueray & same # of items).
Edit:
Audio system:
Six passive micro-sound-processor per ear with a 5x5 matrixes. They measure sound waves, blumes, pressure, pitch, and time. Only the calculated result for a sound is transmitted further (to save 25 times processing power). They form a so called ambisonics recording system.
normal use:
256 bit information from each processor at 100 kHz => 1.2 million data packs a 256 bit = 38.4 MB/s
extremse use:
256 bit information from each processor at 2 MHz => 24 million data packs a 256 bit = 768 MB/s (x25=19200 MB/s ! =6x visual data; my estimation above was close
)
