About 13 years ago give or take when I was ~13 I tried building a telepresence robot. My attempt was quite crude given my limited knowledge and involved a seat in a frame with a helmet attached to the top. The helmet was used to track movement of your head which would move the cameras. I couldn't do walking so I was stuck with a remote control car which fit well with the seat+box method since it was like a telepresence racing game.
My attempt failed but it's great to see someone with real skills+knowledge taking a go at it.
