Wow nice looking robot photos In all honesty I would say that this is way out of your skill set .Walking robots require some very precise engineering and machining not to mention a lot of computer power or even better a lot of computers.However I don't mean to discourage you but some recommended reading would be ,Physics (university level ) Mathematics (differential calculus ) engineering mechanics and engineering computing , there are a lot of books around on mechatronics, you should also study up a bit on human anatomy and learn the mechanics of walking This is just a start as you will also need a metal lathe and mill and some fabrication skills to go with them .I only know basic C++ my self so I am not to sure if that will have the scope for a walking robot The photos you show look like some ones final year university project in mechatronics .Personally I would recommend you start with an easier project than a bipedal and get your skills up a bit
The most basic problem with humanoid robots is balancing... ( and ofcourse the fact that they cost too much $$ than some other types of robots)...so basically , i would say that if you dont have any experience in robotics, dont go for a humanoid just yet (especially if you are doing t all by yourself)....start with a much simpler and basic robot with a differential drive etc....then when you are used to handling servos, and a little complex programming, then you can go for the complex robots..but please be patient , as learning things takes time...BEST of LUCK..!!
I found the creator website, http://dancingdoll-rz.com/main.htmIt's in Japanese and I can't read those.

Hey Wiguan don't let me or any one else here talk you out of trying this project , you would learn a lot from just thinking about it .Any good project starts with a good design and drawing and even more importantly a good design strategy , don't try and design the whole thing at once but instead treat each part as a separate project , for example work on a good knee joint and once you have that worked out and functioning then move to the next part etc etc Do you have a good CAD program ? if you don't you can get TurboCad 12.5 deluxe for free and it is very good or you could use google sketch up .I cant find the link for turbocad 12 but if you do a search you will find it ok ....That photo of the chip looks to me to be a SD memory card adapter .Just for reference on balancing and gyros , the human body has a total of four gyros , two in each ear , a bipedal robot would probably need the same and when we walk we have the equivalent of several thousand computer cores working together to keep us balanced . this is just to give you an idea of the complexity of a walking robot .Or if you wish you could buy a walking robot , there is a commercial robot called "NOW" but it cost around the $20,000 mark . you could find it on youtube and it has had a mention on this forum as well .
You could look at Gait Designer which is part of WebbotLib http://webbot.org.ukIt allows you to create a gait (animation) for your servos and is interactive at design time - ie move some sliders on your PC and the servos on your robot move.You can also play animations.Once done you can upload it to the microcontroller as a standalone.You can also vary the elements of a gait at runtime - ie from your balance sensor you could adjust the ankle joints.Having said all of that - humanoids are really complex - and standard gaits MAY not be the answer as they make assumptions about the environment. In essence human movement is about leaning in the direction you want to go - and then co-ordinating everything else to stop you falling over. A bit like how flying is the art of throwing yourself at the floor but missing!
