Line Detectives  
June 2, 2004 
One person runs the rover program that drives it over the lines for 4 seconds and back for 4 seconds.  
The others down load the data and make the graph as a bar graph.  
From the data the detectives figure out where the rover started.  
Just looking at the graph and checking with the paper and the direction and starting point can be figured out.  
The TAG class cleaned up and looked at Juan's cart that always points South. LEGO Links of Linda Hamilton hamilton@marshall.edu
