Design an end table with motorized wheels and a robotic brain and then
program it to be in certain positions in a room or a house at specific
times of the day or when a person is located in a specific place in
the room.
For example, when somebody sits in the rocking chair by the fireplace,
the end table could move into place so that the person has something
to put their drink on or their book on or whatever. Then after the
person leaves or after bedtime, the end table moves back to where it's
out of the way and not beside the rocking chair.
The next day, it could move into position beside the couch or take a
position in the corner waiting for the appropriate time to come out
with the remotes or some video viewing. Give it a try!
