'High Torque Servo' upgrade cost

Just another thing. Upgrade the servos by pairs or you will have problems with the moves : so it does means 74 dollars just for 2 ankles or 2 hips.

'High Torque Servo' upgrade cost

2012-01-10T21:15:23+01:00

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 should 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,
@hugobiwan

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.
