Totally doable. Someone just has to invest in it. There are already drones that can follow a person and avoid obstacles. The higher-end drones are getting really good at this. It sounds like you needed a ground based drone with tracks so it can go upstairs. These exist for bomb squads but lack full autonomy AFAIK. I think this would be a fun exercise for robotic companies. A challenge to make a track based drone that can play hide-and-seek on multiple floors.
