Virus was the first robot ever entered by what would become Team Yellow Alert. Virus was a 3-sided robot with a trifoil clamping arm.
MegaVirus modified the 3-sided robot formula with an X-axis spinning attachment instead of a clamping arm.
GigaVirus used a standard vertical disc on a weighted rotating assembly. The disc would turn to orient rightside up whenever the robot got flipped, eliminating the need for an X-axis blade.
