aiko V2

sure ,what i meant that he makes a bigger one but with the same principle

i will search for better principle , but also i have to put in my mind the cost
thats why i have chosen the previous one

oh and thank for your fast reply

here is some information that may help

OK , i have got a question , in big and heavy robot like aiko how we suppose to maintain balance
and how many sensors we have to put

hey guys
dont disappear like that

You should probably search on google for humanoid robots and see what they are using... See for example Robocup competition - the teams have to post papers how the robot works ( http://www.robocup2009.org/300-0-teams )

thanks too much its helpful

to be honest i searched million times on google but nothing was perfect
i will try this link
and thanks for reply

what the CPU that Aiko V2 will use
and how much GHz it will have

i wonder if he can use a mini laptop instead of a main-board in aiko
i think a mini laptop will have a little heat
i dont know if it will work or not
just a suggestion

i have a question about aiko V2
can she make face expression like sad ,smile,mad,board
or something like that

Yes, that was one of the new things that was worked on for v2.
The skin itself is another matter, however Le is making progress on that too.

wow ,amazing .
so now she can smile for MR.LE

will he use servos to move her lips or motors
i hope motors because servos make a noise

You can't say that. Sevo is just a motor with a gearbox. If you don't want noise you can use solenoids or muscle wires...or some low noise ball bearing servos...

i am myself have a servo its noisy because of the gearbox
and you can hear the noise from aiko mouth in her video

which is why most androids built (big budget ones anyways) use pneumatic actuators.
look at some well-known ones, like repliee, dion, actroid, and jules.
all of those are nearly silent when they move, but pneumatics makes the cost skyrocket, and pneumatics cannot support the weight of the bot.
i can't recall it's name, but that grey baby robot? it's all pneumatics. while it is very quiet, it can't stand. and pneumatics require pressurized air, which requires a compressor inside, or a large external compressor.
servo is a good choice as it adds minimal complexity and takes a minimum of space and money.
that answer your question?

i see
i was wrong
but is their any solution for the sound of the servo
without changing them

spring wrote:but is their any solution for the sound of the servo without changing them

You can disassemble it and put vaseline (something like that) in the gearbox to lower the friction and noise...

oh ,thanks i will try it
maybe MR. LE should try it

i found this servo they say its noiseless
