Perhaps the classic Milton Bradley game of Operation is easier if you’re not trying to remove body parts from a tiny person. Now Cavity Sam has grown to fully 8 feet tall! Engineers Benjamin Lehrer and Jonathan Roach of Spot Technology made this enormous version of Operation in which the player uses a CNC arm controlled from an arcade cabinet to rescue Sam from his ills.
Just like in the original game, you have avoid the edges. The surgical arm is magnetized to pick up the game pieces. You can see more photos here.
