Ragin Scotsman is, indeed, bigger and badder. Built in 2011, its superpowers would intimidate Ironman. According to Dr. Yeh, it has the “acceleration of a race car and the aggressiveness of a bulldog.” It can get under its opponents and forcibly throw them against the wall. Not to mention its flame thrower, which can melt their electronics.
At one 2012 event, the Science Channel was filming fights for a new show called “Killer Robots.” Initially, Ragin Scotsman wasn’t one of the stars; however, after the producer watched its aggressiveness and, of course, its flame-throwing ability, Ragin Scotsman was filmed fighting other robots.
Despite its toughness, Dr. Yeh says this robot rarely beats top-ranked rivals, “Sewer Snake” and “Original Sin.”
“These robots are very talented,” he says, adding that they have fought over 100 times. “Ragin Scotsman probably has 40 fights under its belt. Every time we fight, we will win one out of four fights against them.”
He says drivers must learn to anticipate the other drivers’ moves, which takes practice. Some of his friends analyze each fight, studying driver habits so they can predict maneuvers. For example, after every hit, one driver may always signal his robot to turn left.
For the most part, he believes good drivers are able to “negotiate that sweet [vulnerable] spot” before destroying the other robot. He refers to some robots as one-hit wonders. After performing the single task they were designed to do, they have nothing new to offer and end up losing.
Break ‘Em, Build ‘Em
Win or lose, what attracts Dr. Yeh to the hobby is the engineering, building, and camaraderie. He says the robotics community is one big, happy family. Even if his robot gets destroyed, friends will help him rebuild it so it can later fight other robots, including their own.
There may be one more robot in Dr. Yeh’s future. Although he hasn’t made any commitments, he envisions that it would involve pneumatics, using pressurized gas to lift or flip challenging robots on their heads or vault them against walls.
Until then, Dr. Yeh keeps asking himself one question—how can he use his mechanical, engineering, and electrical talent in medicine?
“I’m still trying to figure out if there’s a connection between the two,” he says. “Where’s the bridge?”
Regardless of the outcome, he’ll continue enjoying this hobby. Unlike his day job, he says this is one activity where no one demands anything from him.
