The class programmed the RCX robots with RoboLab Investigator
on three computers and the smart board computer.


They ran the program and uploaded the data.

The goal is to figure out where the robot started and stopped.

See where the robot crossed two line?

To confirm that they figured out the start and stop
they ran the robot over the hypothesis area and uploaded the new data.
It definitely confirms it correct.


The data from the Mars mat was pretty uninteresting so we flashed a light during the run

and check to see if we could "see" how many flashes.
The students really got it.
