RoboSub 2018

| Noah Limes

San Diego, California

The climax of my first year’s work on the Underwater Robotics Team! I flew out to San Diego from August 2nd to August 6th. Our team placed 7th in the competition, which was a huge milestone and jump for the team. I learned a great deal from seeing the goal–the reason the older team members were so dedicated during the year. I really, really look forward to next year on the team and hope to switch from the Electrical to the Software subteam. Software is really a critical part of the competition and it excited me to just look over the software guys’ shoulders. I thought to myself, I want to be a part of that! I have high hopes for the future with this team, I feel I can contribute and learn! Robosub 2018 was a very good experience.

Year in Review

| Noah Limes

First Year

(2017 – 2018)

I learned a lot about myself. I realized how confined I had once been to a risk-fearing mindset. I was thrust into this overwhelming new environment. I made many new friends and connections. I adjusted my study habits to the increased difficulty and workload–I learned to block my assignments into smaller, more manageable chunks I could complete proactively. I developed this way of summing it up: “In high school, if I studied I was absolutely guarenteed an A. In college, if I studied, I got a C. If I didn’t, an F.” I was exposed for the first time to new skills, to name a few, Autodesk Eagle and PCB circuitry with the Underwater Robotics Team , FL Studio, a music production program, Solidworks, MATLAB, C++, and much more. I went to career fairs and applied online for internships. Unfortunately, I came away with no internship for the summer. This proved to be a blessing in disguise, because I was able to complete my major requirements with summer classes, appreciate much-needed time with my family, pick up skateboarding, work at a cafe, and attend the 2018 Robosub Competition in San Diego. Overall, I am embarassed, pleased, grateful, and thoughtful about my first year at Ohio State. I have really grown a lot. I am hopeful for the future!

IEEE Student Activities Conference 2018

I was on the sumobot team, where we designed, built, and competed with small robots who tried to push opponents out of a ring. One was a kit bot and one was a scratch bot. I learned a lot from the process.

This year SAC was hosted at the University of Pittsburgh. Our team did not place.

The experience was valuable. I think next time, we should commit more time and planning for the bots.

Coprocessor Rev 2

 Rev 2 tackled the same goals but with manditory fixes to Rev 1’s problems. One notable change is the switch connector, which is a Nanofit jr. Because I couldn’t find any precreated package online, that part on the board was actually a custom part I created in Eagle. That was nice because I got to learn how to do that.

Coprocessor Rev 1

As a first-year student and a new member of the Underwater Robotics Team, I was tasked with seeing the Coprocessor Board of the robot to completion. The board played a critical role in Riptide(the bot’s name). Basically, the board handled the sensor data, handled the switches across the bot, and relayed instructions to the thrusters. I had no experience beginning with this project so I received a lot of help from the experienced team members and I owe a lot of thanks to them. I learned how to use Autodesk Eagle to create the PCB schematic, how to search for parts, create my own custom parts in Eagle, how to physically route the board, how to solder surface mounted components (though I can use more practice) and many other subtleties. It was not without problems, of course. I accidently switched the connections for the JTAG header, I orriented the power jack in an inconvenient direction, I ordered the incorrect USB connector, the Molex Minifit Jr. was an unneccesarily large component for its use, I used incorrectly sized resistors, and I’m sure there were a few other issues. My soldering also needed much improvement (I did not solder the coprocessor chip if you are wondering. That was a much more experienced senior team member). The firmware programmers on the team found work arounds for the JTAG issue but there was definately a neccesity for a Rev 2. Another meaningful thing I took from this experience was throwing yourself into unfamiliar territory is difficult and stressful, but the fastest way to learn. I learned quite a bit really fast and am really glad I am on the team. I look forward to continuing with the team all 4 years.

About Me

| Noah Limes

I’m interested in using my passions and abilities to make a impactful difference for others. For me, that means robotics, bionics, computers, electronics, energy, and space. I am studying Computer Engineering and Business. I am a member of the OSU Underwater Robotics Team, the OSU chapter’s IEEE Sumobot Robotics Team, and Green Engineering Scholars. I am eagerly seeking research opportunities and internships.
