Nothing had changed from the previous weekend when we first wired them up and nothing changed after giving it that power restart. I am completely stumped on what is going on. No shorts, no PWM connections. Just the power is hooked up.

Did you calibrate the sensors? If not, maybe it's just changing light conditions or where you have the robot located.

Calibrate the sensors on an appropriate section of floor after putting in fresh batteries.
