I am a designer. I create SketchUp 3D drawings of items that intrigue me. I did a lot of designs related to a human mimicking robot. Mostly I use science topics and science thinking to create (what I believe is) potentially physically real objects that currently do not exist either because no one has thought of this item or the general opinion is that this problem cannot be solved. I like to show a design and say “Well… I think this would work.” Dr. Gray
