Where finding powerful and special servomotors?

Hello,

i need special motors for my humanoid robot project to reproduce this movement https://upload.wikimedia.org/wikipedia/commons/2/2e/Pronation_and_supination.jpg arm and others also, how to call this type of servo ? I also wanted to know where I could find very powerful servo, looking around 1000kg.cm and 0,5tr/s, any ideas?

Re: Powerful ServoMotors

I would take a look at InMoov if you are building large arms.  I don’t think it does pronation and supination, but you might find it helpful for ideas on other joints that need a lot of power.

I would check out ServoCity, specifically their Servo Gearboxes and ServoBlocks.
