Demo of the CO2 Turtlebot

We tested the CO2 "Turtlebot" - a carbon dioxide sensing robot made from Legos Mindstorms. The Turtlebot reads the CO2 level from a sample in the air, then draws the results on a long sheet of paper. The end result is a histogram graph of CO2 measurents which resemble blades of grass.


The Two Rock 4-H club will be showing its Turtlebot and many other technology projects on October 2, 1-5 PM during the National Youth Science Day in Walnut Park, Petaluma CA.
