Any time the robot rotates, the bearing would tend to stay still and
possibly block a hole. Also, assuming you try to correct the robot being
out of level, the bearing would not move, until the ring was unlevel in a
different direction.

I have thought of a simple level sensor that would use light sensors, a
ring pipe, and a ball bearing. Drill holes through the ring, aligned
like
spokes. Place light sensors on the outside of the ring, facing in. Set
the
ring like a wheel, and add a light source in the center, and the ball
bearing
will block the light of the lowest sensor.
Not much use for MindStorms except as a binary, but some of the sensor
multiplexing might make this workable.
