4dof or 3dof platform for 2 people help!!!!!

[rodrigo203203]

hello, I am new in this area and I am thinking of building a 4dof or 3dof platform that is able to move 2 people, I will place 2 images that would represent my idea.

to see the images I will link my album here
I am thinking of using geared motors to move the structure but I am not sure what capacities to look for, what recommendations can you give me?
Or do you know of any guide with a project similar to this one?
