I need help choosing a servo motor

I am working on a school project that requires me to build a robot that is fixed to the floor but rotates around the hips. I am looking for a servo motor that can rotate the hips using a joystick/controller (around 35 lbs of weight). Should I use a servo motor and if so, what torque rating should I get?

Hello @UnitaryMethod and welcome to the RobotShop forum!

Since you mentioned “hips” I’m guessing you are referring to a humanoid robot. Is that correct?

Do you need it to rotate along the z axis? If that’s the case then you could use a “base rotate” kit, for example:

And yes you can use a servo.

These equations can help you calculate the torque needed:

I hope that helps!
