Annika O’Brien works full time making cool robots. She also founded the popular LA Robotics Club, which has over 1,200 members including high school students, hobbyists, and professionals who share an interest in building robots. The club meets in real space to work on projects and participate in presentations, as well as holds classes as part of their community outreach to under-served teens.comingtobayareamakerfaire_2013

Annika’s boundless enthusiasm and outspoken demeanor jumped right through the screen at me as we met via video chat to discuss her experience on SyFy’s ground breaking show, Robot Combat League, where teams control giant humanoid robots duking it out in an arena.

“It’s like WWE wrestling with robots. It was a concept that no one had actually done before,” she said. “It was a helluva lot of fun.”

Contestants were paired in teams and assigned one of twelve robots. The robots were designed and created by Mark Setrakian and his team. Annika says she really enjoyed working with him.

“Mark was awesome. He designed those robots. Not all by himself; there were a lot of people involved. But after meeting him, I don’t know of another person who could have pulled it off like he did. I think they got the perfect guy. He’s got that evil genius kinda thing going for him too,” Annika laughed.

Annika and her teammate Keisha Howard were assigned the robot Game Over, a heavily armored monster with good mobility. Keisha, a gaming and geek culture enthusiast and founder of Sugar Gamers, was the ‘jockey’, who controls the upper body and arms. Annika was the ‘tech’, who drives the robot. The two team members needed to work in perfect concert to make the robot move and fight effectively.

Game Over glares out at his opponents with a 24″ monitor embedded in his torso.

What was it like controlling a giant fighting robot?

“There was a lot of skill involved. There’s a programmed step cycle. If your leg is up in the air and then you stop mid-step it will drop to the ground. I could time it so that when I needed to go forward or retreat or side to side it was when I had just completed a cycle.”

We discussed some of the weak points of the robots. The six hydraulic actuators in the abdomen were susceptible to damage. If one or two of them were destroyed, the additional forces on the remaining ones could cause a total failure.

“That really happened,” Annika told me. “Twice a robot got completely ripped in half.”

Training for the show was serious business. Controlling these massive machines takes practice. Annika asked a lot of questions during training. She wanted to know just how these robots worked.

“When I first sat down in the chair, I had no clue,” she said. “It was almost like working with cars that stand up. It felt more automotive and industrial than the types of things I’ve done before.”

Each fight consisted of three two-minute rounds. Many of the fights didn’t make it to the third round. The damage these robots dished out is hard to appreciate. Annika was surprised by the shear size of the robots.

“You had to keep a four foot safety radius when the robots were powered on. It’s a thousand PSI (pounds per square inch) in one punch. It could knock your head off.”

Between rounds, each team had 20 minutes to make any repairs and be ready to fight again. The teams had help from a pit crew, but all the major calls for fixing the robots were their own.

“The time limit was very strict. It was pretty stressful,” Annika told me. “I felt confident. The whole time before we had to fight I was constantly telling Keisha the terminology, because she didn’t know much about robots. So when I described something that was broken, she’d know what I was talking about.”

Game Over fought A.X.E. in the third episode. Team A.X.E. consisted of jockey Andrew Montanez (a mixed martial artist) and Ross Mead (a computer science PhD research fellow at USC). Game Over towered over the shorter A.X.E. and had a longer reach, but A.X.E. was heavier. Annika told me part of their strategy was to use their robot’s longer arms to hold A.X.E. out of striking distance.

About half way through the first round, Game Over’s left arm was damaged, and it began leaking hydraulic fluid. The sight of robots spewing their precious fluids was a common occurrence on the show. The fluid not only powers the robots’ actuators, it is super slippery and affects their traction.

Annika told me, “We had lost so much hydraulic fluid. We flooded that arena.”

Annika and Keisha continued to fight on despite their broken arm. Keisha rained blows upon her opponent and A.X.E.’s left shoulder armor went flying across the ring, leaving the arm’s actuators exposed. But then A.X.E. scored some more damage on Game Over, affecting the right arm. As the round one bell sounded, the announcers and the other contestants seemed to agree that Game Over had taken the brunt of the damage as more hydraulic fluid leaked onto the floor.

Annika, Keisha, and their pit crew worked furiously to repair their robot’s right arm, and they continued into the second round. Both robots hammered away at each other. A.X.E. dished out more damage to Game Over’s right arm, but it continued to function. The crowed shouted in wild excitement when Keisha managed to knock A.X.E.’s actuated head clean off! Of course, since there was no brain inside the robot’s head, A.X.E. was able to keep fighting.

As the second round ended, onlookers felt that Game Over might make a come back. However, the robot was badly damaged. They were basically down to one elbow actuator still functioning on one arm.

Game over for Game Over?
Annika, Keisha and Mark discuss whether Game Over can keep fighting.

“It was up to us whether we wanted to go on to another round. Keisha and I almost dropped out. Mark actually pulled us aside and told us it didn’t look good. Knowing him and knowing he knows this robot… Both of our arms were broken. We decided to just go out there and swing our robot like a weed whacker.”

Annika and Keisha’s fight was the first one on the show to go all three rounds. Despite managing a pretty effective fight in the third round, the bout went to A.X.E.

“It was pretty close,” Annika told me. “I actually thought we won until the judges announced their decision. I’m pretty proud of the way it went.”

Annika and Keisha’s loss meant they had to leave the show, but they had put up a really good fight. Annika was very positive about her involvement.

“The best part of the entire experience was making all these amazing friends. We all got along really well.”

She stressed the feeling of community on the show. From the other contestants to the robot crews to the film crew, everyone was great to work with.

“It was kinda like being an outcast of some sort and then walking into a warehouse with everybody who totally gets you,” she said. “A lot of the jockeys weren’t robot savvy, but they were really eager to learn. You’d think getting a bunch of jocks mixed up with a bunch of nerds that there’d be kinda that tension, but that didn’t happen.”

Annika told me she enjoyed speaking with the people who built and maintained the robots. They were really knowledgeable and they knew these robots inside and out. Their expertise impressed Annika.

“The people who were in charge of the robots were amazing to work with. Every day I just enjoyed the people I was around. This guy totally out-nerds me,” Annika thought about one robot crew member in particular.

SyFy hasn’t announced yet if there will be a second season of Robot Combat League.

“I would do it again if they called me,” Annika assured me.

Despite having such a positive experience, there was one dark cloud over the show for Annika. The reaction some of the women on the show received around the internet was troubling. Some people posted some very negative things that simply were not true, and it angered her.

“These are real women who happen to look good in a tube top. These are women that are brainiacs. Even the fighter girls, they may not know much about robots, but they were really smart.”

So what’s next for Annika? She’ll be a speaker on the Arduino panel at Bay Con later this May. She also hinted that she’s got something big coming up, but she’s not free to share the details yet.

“You can ask me again in a little while. It’ll be like Junkyard Wars meets Myth Busters meets Extreme Makeover. It’s freaking awesome.”

I can’t wait to hear about it.
