Walker Bot has a problem

The bot goes very excited and flips over , the MPU sensor position has no effect on the bot motor outputs

the codes have been taken from the following site

did every thing with PID but there is some thing else wrong , may be the mots are not good enough for a heavy load , batt is heavy . I am switching to steppers , and light weight then will be able to manage with PID settings

Steppers are not good for this application due to their low torque. You need high torque motors to carry the load. Steppers may fail to do so or heavy steppers will be required.
Now talking about you servos getting excited. You should reach to the desired angle in steps. E.g if you wanna go to 90 degree then make steps of 2 degrees per steps with small delay. This will imitate a smooth walk. Rather than fast reaching to 90 degrees.

First thank you for joining in , and your advise is very intuitive. High power custom built servo is the only answer You are right. will be using a very powerful reduction gear motor (12 volts 20 amps Car wiper gear motor) , and will convert it into servo with rotary encoder. for W.Bot

I wonder how will the team work , we are borders apart , and each one has to be a part of this design . and if ever it got financed , the tangible parts have to be with each member of the team ,so that the real life development is done by each member physically making it , then programming it and eventually testing it in real life scenario. which means , being worn by a human. as this is not a hobby project , but a support for those parents who have a special child who is in the wheel chair. and this project is the property of such parents. So that after development it can be delivered on huge sacale , in that each member will be an outlet of this support
I think the prototype scale model will be easy to afford and manage , once tested for all what the design should be. the development of the Real WalkerBot can be done. yet one set of this prototype will be
suggested part list is att as img.
Team leaders are requested to add if there is some discrepancy.
Please find out the cost so that we may know the financing part of it.
The project has to be completed by all , financing or no financing
AS the society needs to bring there special children to normal walk of life , One done with this
We will start scaling it higher for adults WalkerBot suits.
Your participation is your achievement
and this is a team of team leaders as each one will independently build to make the child walk
Good luck leaders we are IN

financing will not be constraint as things happen when the goal is achieving for others , and the reward is a petty matter The highest reward is Satisfaction and Heavenly skills

forgot the remote controll parts , the remote control will be used to teach the bot what he has to do and how
keeping the self learning of the WalkerBot in vision

this is stage 1 Phaze 1 , prototyping of scale model To develop intelligent software and testing the implimented
programs . inducing self learning , rather hands On experience
