ELI5: Why are bipedal walker/machine so difficult

What makes bipedal machines so diffcult to make, like is it due to it's stablity if so why can't an accelerometer fix it ? and also why can human do it so easy even though we have less computing power ?

First thing i think we can remember is its not easy for humans to be bipedal. We have brains that have evolved for it, and it takes years for us to learn to walk and walk well. Have you ever seen a kid walk/run, they look clumsy, trip and fall, etc.  So its not easy to do for humans.

Second thing is that the human brain is an incredibly complex computing device. While it may not do math as fast as a computer, there are plenty of things it can do that a robot cant. We can solve Captcha's without much issue and do other things.

The final part is that calculating the center of gravity is tough with a lot of moving parts. The human body is good at small movements with muscle twitches, but robots require hydraulics or power to move arms and can't make small adjustments as easily.
