Let's try to figure out what would be a "really low-cost robotics starter set" with 2 motors, Arduino compatible controller, and a few sensors.

Cheapest robot I can think of would be using two small motors and two photoresistors and either make it run towards or away from light. You can probably get the cost of that down to around 2$ :-) (hm - you might want to throw in some potentiometes to adjust sensitivity, and some transistors for voltage regulation... shouldnt be such a hard task :-) ..)
Add an arduino for upwards compatibility to later stalk cat or mailman.
