I want to make robotic tail

I am trying to make a tail for my future bipedal, but step by step, I tried making it with a lot of discs glued to rubber tube so it could flex. Than I drilled 4 holes in every disc and pulled fishing thread thru, giving it 2 moving direction. I will need to thread every couple of discs to have more precise movements available. That makes the number of servo needed more than 40.

Is there some better way to mechanically pull this off?

I looked over Internet and didn’t have luck finding similar application. I appreciate any thoughts on the topic. And yeah I plan controlling everything with raspberry 3 and bunch of i2c power distribution boards. Planing to write program in python and later in a project translate to c++ for efficiency.
