Today's class was dedicated to working on our project two.  Today I was having trouble getting my line followers to work correctly.  For a while the right and center line followers were not giving good values between white and black.  Eventually I saw that part of the sensor was sticking out of the plastic case, so I pushed it back inside and then they started giving better values.  But they still act strange when I put the robot on the table.  It would just sit still for a few seconds and then shoot forward without stopping or making turns.  I did find out what value the IR sensor would have to read in order to stop the robot in a position so the claw can grab an object.  I also think that I will need to slow the robot down.  I think that is a reason for it not making turns or stopping in time, it's moving too fast.  I will need to play with the values going to the motors until I find one that will have the robot going at a more appropriate speed.
