I calculated the acceleration of gravity once with a light sensor, touch sensor
(for timing purposes), a ruler, and ROBOLAB 2. It didn't involve a whole lot
of data so it didn't make it into the Sample Projects of ROBOLAB Investigator,
but some other ones that did are:
1) Calculating the speed of a LEGO motor (both with angle sensor and light
sensor and spinning black and white wheel), 2) graphing temperature and light
overnight outside my apartment window, 3) "reaction time" (like you described),
and 4) "doorway" (monitoring who comes in and out of your room with the light
sensor). All of them are fully functioning examples with graphs, programs,
calculations, etc.
Incidentally, in my book "Creative Projects with LEGO Mindstorms" there are
several non-robotic projects, including 4 kinetic sculptures, a bird feeder
that automatically takes a picture of a bird that lands on it, and various
science experiements like a repeat of the doorway experiement, taking data
inside the refrigerator (light and temperature), and calculating speed and
acceleration of a robot, and calculating speed of a motor.
other things in the book that aren't the standard robot: Decoder, tickle-me
lego robot, elevator, and "painter" (robot that drives around and drips paint
on the ground at programmed intervals and places)
