The arm-wrestling robot was developed by Professor Chul-Goo Kang and his colleagues at the Institute for Robotics and Intelligent System (IRIS) of Konkuk University. Robo Arm-Wrestler greets people when they are approaching by saying "Hello", "Nice to meet you", or "Please take a seat for a match", and so on. Robo Arm-Wrestler has some artifical intelligence which automatically adjusts its strength for the challenger and it also considers its competitor's attitude and reflects his will and tenacity in deciding who wins.

John Grizzly: "When I get to the table, that person, I don't care who they are, they're my mortal enemy. I hate them."

Harry Bosco: "My whole body is an engine. This is a fireplug" [makes a fist] "... and I'm gonna light him up."

Bob 'Bull' Hurley: "I drive truck, break arms, and arm wrestle. It's what I love to do, it's what I do best. Being number one is everything. There is no second place. Second sucks."
