Measuring the Center of pressure of human steps

Projects Programming
1

I'm working on a project to find the center of pressure (COP)point
for human steps using four load cells placed under a platform and using the COP coordinates ​​to calculate the gait parameters such as step length, step width, etc. I am looking for help with the code for the project on the side of calculating the COP for each step separately.

Hi @alisameh2000,

welcome to the arduino-forum
You should read this sticky thread to

get the best out of this forum

From this short sentence the help would be that your potential helper would have to learn all the theory about center of pressure. And this without seeing your platform and wihout seeing your sensors.

This is pretty demanding don't you think so?

So help us to help you by reading the how to get the best out of this forum.

As soon as you post some formulars and a first attempt how these calculations can be coded the help rushes in.

best regards Stefan

Post the code, using code tags, and explain the difficulties you are having.

If you are looking for someone to write code for you, consider posting on the Jobs and Paid Collaboration forum section.

It appears commercial systems are available produces a color-coded map of pressure:

wouldn't you take the average of the moment (force * distance) in both the vertical and horizontal directions resulting in the x and y positions of the COP

#     x      y  force   xMom   yMom   Ftot   xCop   yCop
