This is some cowboy engineering and i love it. totally shooting from the hip, but still finishing up with a nice long-form post.
like other comments mentioned this is super impractical but that's not the point. building a robot finger to push a button at the push of a button is a hilarious saturday afternoon project
It's one of those projects that lets you flex your problem solving muscles in a low stakes environment. Taking "I wonder if i could..." and running with it
good job bert!
