Justin Ridley - This Is How I Work

Justin Ridley is our second mentor from FRC#118 The Robonauts. He is another FIRST success story, having started on a FIRST team in high school, mentored a team in college, started his career as an engineer, and continues to mentor a team now. Justin is the key man behind 118's recent run of exceptional reveal videos. You can hear about his job at NASA, how a skiing accident brought him into robotics, and more.

What inspired you to do what you do? Tell us a story.
My sophomore year of high school, my math teacher (Woodie Flowers award winner, Kyle Hughes) asked me to join our school’s new robotics team. I declined because I wanted to spend the winter on our school’s ski team instead. It turns out I must not have been a very good skier because I ended up breaking my leg during a race. With skiing out of the picture, I decided I might as well join the robotics team.

There are a lot of stories about FIRST changing people’s lives, and I feel like mine is probably pretty cliché. But cliché or not, it’s just true. I didn’t have any real interest in engineering prior to FIRST. With my gimp leg, I found myself in an environment that slowly changed the way I thought about things. I had fantastic mentors on Team 27 and due to them, and the program, I learned that engineering was definitely something I wanted to pursue. This led me to go up to my mentor’s alma mater, Michigan Tech, and study engineering. Three other alumni and I started a FIRST team up there and it has continued affecting my life since.

Being at Michigan Tech I had the opportunity to apply for a co-op at NASA down at the Johnson Space Center. This allowed me to get my foot in the door for a full time job here, which I love. I can honestly say that I wouldn’t be where I am today if it were not for FIRST. I can probably say the same for that broken leg, but I like to give most of the credit to FIRST.

My story has inspired me to continue mentoring students in the hopes I can help them make similar stories of their own.

What is your day job, and how’d you get there?
I started answering that question above. After coming to NASA full time, I started my career at NASA as a Flight Controller for the International Space Station (ISS). For about 7 years I worked with the group operating all of the life support systems on ISS from Mission Control. During this time I volunteered as a mentor on The Robonauts (118). After years of working with the other mentors on the team, they convinced me to transfer to where they do their day jobs, the robotics group here at JSC. Our job is basically to build really cool robots. It’s like FIRST with a bigger budget, and I love it.

What is your favorite story to tell about robotics?
Like most of our peers, there are too many stories to pick one favorite. A lot of my favorites involve the intense moments between matches of a tournament, making repairs, talking strategy, etc. Back in ’08 our robot, Ballacuda, had a crab drive we had built for a few years. Something within it broke during the Lone Star tournament and in the process of fixing it after a match, we induced some strange electrical problems. One thing led to another and mechanism after mechanism seemed to have some issue. I specifically remember somebody yelling, “Just tell me what we have on the robot that works!”, which space nerds will recognize is quite similar to a Gene Kranz quote from Apollo 13. Even with all the stress and excitement, I couldn’t help laughing at the time. We struggled through each match, trying to get things back to 100%. At one point we sent the robot out with only three of the four wheel modules… bobbling around the track. There have been many intense moments between matches since then, and once in a while I like to jokingly yell out that quote while there are a dozen hands in the robot frantically trying to fix something.

What's your favorite robot that you didn't help build?
Chief Delphi’s (47) 2000 robot. Back then we didn’t have all the motor options we can utilize now. Building complex mechanisms was a much more difficult task and robots were often a lot simpler. Simple, however, was not part of 47’s vocabulary in those days. The arm/manipulator on this thing had like five different motions to it. It would snake down to fly under the bar and then extend back up to dump balls, all with a swerve drive underneath. One of my favorite FIRST memories would be watching one of the first elimination rounds of their first tournament. After dumping a load of balls they swerved over to the opponent’s goal and started sucking their balls out. Almost nobody in the stands had ever seen them do this, or even know it was possible (they hadn’t used that feature until the finals). Needless to say the crowd went absolutely nuts. This robot always serves as inspiration to me… keeping it simple is great and all, but sometimes it’s fun to shoot for the moon and really do something crazy.

What apps/software/tools can't you live without? (Work/Robotics/Home)
I use this all the time: http://www.engineeringslidechart.com/
The couple of things it doesn't have, I added myself. There’s probably an iPhone app with all this info, but there’s something about having a sliding chart in your hand that really makes you feel like you’re doing some real engineering.

What's your workspace setup like? (Work/Robotics/Home)
Nothing too special about my workspace. Generally a mess of papers, parts, random nuts, bolts and tools, all of which prevent me from finding my trusty TI-89 calculator and Mitutoyo calipers when I need them.  

What do you listen to while you work?
Spotify. I have a fairly eclectic musical taste. I’m a big fan of music festivals, such as Sasquatch or Austin City Limits. Look at the lineup for any of those from the last 10 years and there’ll be a lot of stuff I enjoy. I also listen to NPR a lot, and sometimes I’ll bring up something like The Jimmy Fallon Show on Hulu and listen to it in the background… what can I say, I enjoy distractions.

What’s your schedule like during build season?
Officially our schedule is MWF from 5-9 and 12-9 on Saturday. Unofficially… well let me just say that after 16 years I have not yet figured out an appropriate robot/life balance during build season. I think because building these robots just demands so much. One thing I love about 118 is that we’ve got incredibly dedicated people involved. That dedication is contagious and there’s usually people working on some part of the robot 5-7 days a week, many times very late into the night.

What everyday thing are you better at than anyone else?
I wouldn't say I’m the best at anything. The other 118 mentors would tell you I’m really good at a week 3 panic attack about the direction of our robot and if we’re going down the right path.

What's the best advice you've ever received?
Nothing specific comes to mind, so I’ll share some advice I wish I would have received. If you’re a high school student about to start college, take a break from FIRST. It’s too hard to be a mentor, keep your studies up, and enjoy life the way you should be in college. In addition, don’t stress about graduating as early as you can. Go out and get internships and co-ops, study abroad, take extra classes. In my opinion, all of these things are way more important (especially the co-ops) than getting into the real world a year or so earlier.

What is your favorite guilty pleasure?
In the off season I see quite a few movies and watch a lot of TV. I’m sure there’s something better I could be doing with my time than catching up on Breaking Bad or binge watching The Wire.

Fill in the blank. I'd love to see ________ answer these same questions.
Dennis Hughes of Team 27. He taught me a lot back in the day and has plenty of good stories about robots.

Anything else you want people to know about you?
In 2005 I made a short video just for our team of our robot at the 3 week mark in order to get everyone excited about our progress. I continued this the following years and this evolved into the Robonauts release videos. Almost more than building the robot, I enjoy making the robot videos. Our team has put a priority on trying to make our robots look good, and showing them off in our videos. In the last days/hours of build season when we should be fine tuning mechanisms and getting some drive practice, we instead spend that time shooting down helicopters, launching prototypes through driver stations, and making sure the robot lights are working just right so we can get the perfect shots of it driving around. In other words, our priorities are a little out of whack, but we wouldn’t have it any other way.

  1. Justin,
    Thanks for sharing you personal story. It is so inspiring and motivating to see FRC mentors share about themselves. This is one of the great things about FIRST that I find so different - individuals who are mentors/counterparts to so many that never even realize they have impacted.
    Thanks
