I am considering purchasing the Robophilo as my first humanoid robot. I have been into robots for years but this is my first experience with humanoid robots. I found on robobrothers website http://shop.robobrothers.com/product.sc?productId=23&categoryId=1 for $32. If I wanted to start out replacing all the basic servos, how many would I need to buy?
Also, I know very little about robotics (all the kits I have done require no soldering etc) so how difficult will it be to replace the original servos.

Hello from France.
I upgraded first the hip servos, and after the ankles servos. Moves are much better with this replacement.
So i could use the original ankles servos to upgrade the knees.
I also could have taken them for the shoulders.
I used tower pro 995 and tower pro 996 R with metal gear found on ebay but i saw on some forums that these low cost servos would one day cause problems. People are saying that for bipeds high cost servos are much better, but i can't afford it.
Concerning my upgrades:
4x tower pro 995 + 2 x tower pro 996R means about 60-70 euros. And i have a problem concerning fine tuning of the ankles... Ankles upgrade makes a difference. Perhaps shoukd you begin with ankles. Then you could always make choices for the rest of the servos/money.
The best woukd probably to use good hitec or futabas servos. More expensive for the same torque (13Kg!).
But the robot can easily stand on one feet and moves fast.
I am interested in sharing about these robophilo tuning questions.
Best regards,
