The motors are surprisingly strong (see more information on Philo's
excellent website: http://www.philohome.com/nxtmotor/nxtmotor.htm
The other parts and (also the plastic toothed gears) are not really
suitable for a "real" camera. (I have choosen the L2 for my experiments
because it is very lightweight (~200 grams), and still offers a decent
image quality through its low (50) ISO ratings.)
There are 3 motors in the NXT starter box: One is used for pan, one for
tilt and one simulates your finger, pressing the shutter button. The
"finger" is a extension Lego brick directly attached to the motor. The
motor's power can be controlled exact enough to even simulate the 2-step
shutter operations (e.g. "AF" and "shutter").
Meanwhile i also bought a compatible mobile phone (there's a remote
control software for mobiles on the Lego website) and i am exalted by
the expanded possibilities this little gem offers: You can remote
control pan, tilt and shutter function "out of the box" - and of course
you can write your own software responding to user defined input. This,
is what i'll do next... :-)
