    Ants Days:

    Most of the parts for the Ants were built in two marathon Sunday construction binges, otherwise known as Ant Day and Ant Day II. Over 28 total hours were spent by grad students, staff and undergrads building gearboxes, microprocessor boards, motor controller circuits, and countless other ant parts. When the pizza was eaten and the smoke settled, there were six new robots in the AI Lab: Anita, Hope, Kisha, Niqi, Sandra, and Tracie. These robots were joined six months later by Dasa, Jennifer, Keila, La Shaun, Lisa, and Michelle.
