How to calculate the installation location of gas stops?

Question

Robotics

There is an idea, I don’t know how to implement it, I’m not friends with physics and mathematics. There was an idea to create an exoskeleton on shock absorbers (gas stops), as an example, I cite the American hulk exoskeleton, he has gas stops at his feet, the essence of the question is whether any calculations are needed to install gas stops, if so, how to calculate?

Answer 1

you will have to make friends with mathematics :)
It's simple. There is a straightened position of the leg and there is a fully bent position.
you need to find such a point on the lower leg so that the distance from the top of the thigh to this point in a straightened position differs from the distance in the gas lift rod bent to the length.
Solved in an elementary way. But you will need a lot of such solutions, so you will have to remember the geometry.
And also remember or study the termex, since the force on this leg will depend non-linearly on the angle of the bend, depending on the attachment points of the rod and cylinder. In short, for this to be a help and not a hindrance, you need to think carefully about everything.
