Not really. I believe this enough to try it soon. :) Two motors to turn
and tilt the camera, and one for a differential drive setup(possibly using
the reverse differential device). All the sensor ports would be used
however - 1 for the ultrasonic sensor and 2 for the rotation sensors. A
datapoint is logged for every tick of the rotation sensor, then a 3d map of
the area is generated. This would require some simple 3d programming on the
computer - easy things like simply transforming a polar coordinate into
cartesian, then into 3d.
