$50 Robot not quite working

[mwmckee21]

I am having issues with my $50 robot.  When I plug in the power the servos work, however they do not react to the photo resistors.  I have even tried to use a potimeter, but that still doesn't work.  Below are some pictures of my robot, note that it is connected on two boards due to radio shack not having the main board in stock at the time of purchase.

check everything with a multimeter and sheck to see if anything is un-connected. It could be that your photoresistors are busted
