Say what you will about the merits of Interstellar, TARS, CASE, and KIPP (I know it wasn't your fault, KIPP!) were awesmely cool robots.
Cosplayer Ochre Jelly's replica cosplay took three months to build and allows him to walk behind the robot while controlling it. A smartphone camera lets him see where he's going. Now if only he could get it to run... or whatever that spinning thing is.
