In just 30 hours, Oregon State University students created wearable technology projects at HWeekend on April 10-12, sponsored by the School of Electrical Engineering and Computer Science. Thirty-five students spanning several areas of engineering formed seven teams and built projects that ranged from a remote controlled arm to a video game.
The event was organized by Don Heer, instructor in the School of Electrical Engineering and Computer Science, who wanted to provide students an event similar to a start-up weekend or app hackathon, but for hardware. It was the fourth event for Heer who values real-world experiences that augment the student’s classroom experiences.
To build their projects the students had a variety of components available to them including tiny computers, NVIDIA Jetsons, motion sensors and motors, and as access to 3D printers.
“It’s surprising how much this relates to my classwork, but also how much fun I had with it,” said Mark Andrews, student of electrical and computer engineering and math. It was the second HWeekend for Andrews.
About half of the students at the spring HWeekend had participated in one of the previous three HWeekend events that were sponsored by Eaton, Rockwell Collins and Micron.
Two projects: The Hand of Glory by Mark Andrews, Paul Lantow, and Conner Yates; and Go Go Gadget Claw by Tyler Gilbert, Ryan Green, Rattanai Sawaspanich, and Keaton Scheible are featured in videos below. The Go Go Gadget team won the Most Innovative award and tied for the Most Helpful award with the Mechanical Calf Assisting Device team.
Graduate student David Piorkowski received an IBM Ph.D. Fellowship Award in March 2015. The fellowship is an intensely competitive worldwide program, which honors exceptional Ph.D. students who have an interest in solving problems that are important to IBM and fundamental to innovation in many academic disciplines and areas of study.
Piorkowski’s research is in the area of software engineering, and aims to create better tools to help software developers debug code.
Margaret Burnett, professor of computer science, and Piorkowski’s Ph.D. advisor said, “David is a rising star. His research stands to fundamentally impact software engineering, and this award recognizes its importance. The computer science research community’s recognition of its importance also shows in David’s academic successes along the way.
“In the five years past his B.S., David won four research internships, and published six ACM/IEEE papers with more in the pipeline. His papers are significant, building a foundation for practical support of software developers’ information seeking. He also “gives back,” mentoring younger graduate students, undergraduates, and even highschoolers. I am extremely proud of his achievements.”
Description of his Ph.D. dissertation from his award nomination:
“Information foraging theory (IFT) has explained and predicted how people seek information, but IFT does not explicitly account for how people forage when simultaneously “fixing” information in the environment. This gap may limit IFT’s applicability to programming.
Informed by prior research in IFT and Minimalist Learning Theory, my research investigates how programmers forage differently when debugging (fixing) versus understanding (learning) code — via empirical studies and constructing computational models — and how software tools can capitalize upon these differences. The results will contribute new, evidence-based theoretical foundations for understanding software developers’ information seeking behaviors, and how tools can support them.”
Claudia Mini’s passion for technology was sparked by watching her aunt play Nintendo NES, although it was not until college that she decided to pursue it as a career. Now an Oregon State computer science student, Mini has found a way to combine her creative side with computer science.
Of those early days hanging out with her aunt, Mini said, “I just loved watching her play and would root for her, but when I would play I’d always lose.” Not deterred, she later became the computer expert of the household she shared with her grandmother, mother and aunt, who were originally from Nicaragua.
In third grade, Mini won a computer in a raffle which gave her the chance to start exploring all the possibilities that computers offered. But she didn’t try programming beyond learning enough html to improve her Myspace page. In a high school class on Adobe Illustrator and Photoshop, Mini’s teacher noticed she liked to help others out and asked her to be a be a teaching assistant in a computer science class. So, although she never took a programming class in high school she had the opportunity to learn more about all the options computer science had to offer through the class she assisted with.
“I thought it was just really cool that there was so much versatility, and you could show your creativity through computer science,” she said.
But Mini had planned to follow in the footsteps of her mother and aunt who were both in medical professions. She applied to Oregon State as a pharmacy major, but switched her major before taking classes when she realized that she fit better into computer science.
“I feel like when you’re in the right major you definitely know it because you’re surrounded by people that have the same common interests as you, and you get along with them,” she said.
To get through her first year of computer science courses, Mini said she was at her teaching assistant’s office hours every day. The strategy not only helped her to be successful, but she also made a close friend.
“She helped me so much, because it was intimidating at first and she helped me get through it. She is definitely my mentor,” Mini said of Sneha Krishna.
Mini not only mastered the material, but she started teaching it herself when she became a teaching assistant the following year for the introductory classes. “I really like seeing the progress in the students. At the beginning I was explaining to people what a function was, and by the end they were learning linked lists,” she said, beaming with pride.
Although she enjoyed computer science, Mini initially didn’t have a plan for her career until she discovered she could combine computer science with psychology, and pursue a career in human-computer interaction (HCI).
“I really like to communicate with people and make software that’s helpful to people, and HCI involves a lot of talking with the user to find out what they want incorporated into the product,” Mini said.
Mini has quickly grown from a nervous freshman learning to code for the first time to a leader for her peers. In addition to being a teaching assistant she serves on the board of the OSU ACM Club as the secretary. She has also gotten much better at computer games, but she still likes to watch others play and root them on.
Brian Benavidez (left) poses with teammates Arron Bellini and Kamil Agrawala after winning the People’s Choice Award at the Engineering Expo.
Brian Benavidez did not expect to have a chance to go to college since he had enlisted in the U.S. Air Force immediately after graduating from high school. But it was the experience in the military that gave him focus and direction that he credits for his success in school. And the scholarship support he received from the School of Electrical Engineering and Computer Science inspired his desire to give back.
Benavidez spent four years in the Air Force including a deployment to Iraq. Most of his enlistment time was in Arizona where he was maintainer for F16s which included working on avionics systems like navigation, fire control, and flight control computers.
“I’ve always been a tinkerer, but that experience really opened up that horizon of electronics and engineering,” he said.
Meanwhile many of his buddies from his high school in Portland went to Oregon State University, and he started to realize he was missing out on the college experience. Through the Enlisted Commissioning Program he was able to come to Oregon State as an Air Force ROTC cadet.
“When I first got here I was in shock and intimidated, but as time went on I got into my groove,” he said. His “groove” included three projects with the CreateIT Collaboratory, a program where student teams work with clients on developing a prototype device. He worked with Tektronix on a modernized user interface for oscilloscopes, The Utah Ballroom Company on light up dance suits, and Texas Instruments on a device for sensing nearby objects.
Culminating his undergraduate experience, his senior design project won the People’s Choice Award at the Engineering Expo. Benavidez with two friends created the “Intellicycle,” which could be added to any bike to measure speed, distance, cadence and temperature and send the data to a smartphone. The system also harvested energy from the front wheel to charge the phone and bike lights.
Having faced the challenges of being an older non-traditional student, Benavidez wanted to do more to help other veterans at Oregon State succeed. He served as the president and vice president of the Veterans & Family Student Association (VFSA) on campus, to help veteran students create a sense of community. Inspired by his experience of receiving scholarships, Benavidez initiated the Allworth-Holcomb Memorial Scholarship Fund for outstanding veterans at Oregon State.
“Getting a scholarship is very, very humbling. It’s hard to take money from someone just because you’re doing your job,” he said. “I didn’t really feel comfortable just accepting the scholarships without finding a way to give back. So, this was my way of saying thanks for all these resources given to me.”
Benavidez graduated June of 2014 and is working on a master’s degree in cyber intelligence studies through American Military University. Currently he is commissioned as a second lieutenant, and will be attending the Intelligence Officers Course with the U.S. Air Force.
Kevin Hess demonstrates the mobile biomarker detection app at the OSU Engineering Expo.
Three Oregon State University computer science students worked with the Remcho Research Group at Oregon State to develop an iPhone application to automate the testing of enzyme slides.
The biomarker detection app was developed by Kyle Cesare, Kevin Hess and Joe Runde for their senior design project. The application speeds up the process of analysis, and will allow medical personnel and researchers to perform the tests without expensive equipment, such as remote locations in developing countries.
The mobile app complements a new type of chemical test the Remcho lab developed to detect whether or not an antimalarial drug is genuine. Many lives are lost to the use of counterfeit antimalarial drugs — an estimated 200,000 a year according to the World Health Organization.
The students are releasing the app under an open source license so others can build on the technology they developed.
“I think we could start to see a huge impact on global healthcare, especially in the developing countries, as people begin to see the power and convenience of mobile devices. I hope that our app helps that realization happen quicker,” Kyle Cesare said.
Sami Al-AbdRabbuh, one of Oregon State’s Solar Vehicle Team drivers, holds up the check-off sheet that shows they passed the scrutineering phase of the American Solar Challenge.
Sweating it out in Austin, Texas this week, Oregon State University’s solar vehicle team was the first team to finish the “scrutineering” portion of the American Solar Challenge. This qualifies them to compete in the Formula Grand Sun Prix, which they won last year. The track race is a qualifier for the main event — an eight day road race through seven states from Austin, Texas to Minneapolis, Minn.
During scrutineering the teams go through a series of tests to make sure the vehicles are safe and follow regulations.
“It went really well. Our team leaders did a great job of preparing us, and I think that’s what made the difference for finishing first,” said Abhishek Raol, one of the drivers for the team.
Next up is the three-day track race. Starting Thursday, July 17, for eight hours each day the teams complete as many laps as they can on the Circuit of The Americas — a 3.4 mile track that includes an elevation gain of 133 feet. Last year the team completed 193 laps (661 miles) which was just a lap ahead of their nearest competitor. This year the competition looks to be stiffer.
“When we won last year, 12 teams competed. This year there are 23 teams including some tough competitors like MIT and University of Michigan,” said Dave O’Gorman, advisor for the team and marine technician for Oregon State’s College of Earth Ocean and Atmospheric Sciences. Teams from all over the U.S. and Canada and teams as far away as India and Iran are competing this year.
Oregon State’s solar vehicle is named Phoenix, in reference to a car fire that in 2011 burned a previous version to the ground. Around 30 students have been working with the team all year to make improvements to Phoenix, and 11 students traveled to compete in the race — four are drivers and the rest work to keep the car operational through the grueling 11 days of racing.
O’Gorman said that the team has had students from every branch of engineering including nuclear and chemical, and even some non-engineering students from time to time.
Abhishek Raol, a student in electrical and computer engineering, joined the team as a sophomore last year because of his interest in renewable energy. “I also really wanted to apply what I learned in school to a real life experience,” Raol said.
Although his focus was on the electrical systems he has also worked on mechanical projects and the integration of electrical and mechanical. “That’s been really interesting for me, to see how electrical engineering works in a whole system,” he said.
Raol is one of the drivers for the team and is excited to start competing. “Not everyone gets to drive a solar car so I took the opportunity. It’s neat to be able to drive what you have been working on for so long,” he said.

Raol said the 8-day road race will be the most nerve-racking part of the event in which the solar vehicles travel on highways and freeways for eight hours a day following a detailed route. Although the car can reach up to 60 miles per hour, under certain road and weather conditions they might be traveling as slow as 15 to 20 miles per hour. For safety, the solar vehicle is flanked by a lead and chase car with the other team members that are at the ready to make repairs along the way.
Although the race is a competition there is a cooperative spirit among the teams that help each other out by loaning parts and offering assistance for repairs. Last year Oregon State’s team also won the sportsmanship award.
“I’m looking forward to working with the other teams and learning about how all the different systems work,” said Gray Johnson, sophomore in electrical and computer engineering.
O’Gorman has been extremely impressed with the team which he has been helping out for the last couple of years.
“The thing that really blew me away is that the students do everything from the initial design, the machining, the welding and the troubleshooting. It’s amazing to be part of because the students really do it all,” he said.
The team is posting to Facebook and Twitter and have a live webcam of the event. Team member, Bonnie Wood, was featured in a story by the Ashland Daily Tidings about the race.
Corwin Perren, electrical team lead, and Billy Edwards, team leader for the Mars Rover, traveled with three other teammates to the 2014 Sample Return Robot Challenge in Worcester, Mass..
Five members of Oregon State’s Robotics club on the Mars Rover team took their finals early so they could travel this week to Worcester, Mass. for the 2014 Sample Return Robot Challenge. The event on June 9 to 14, is hosted by NASA and Worcester Polytechnic Institute and has nearly $1.5 million available for prize money.
Before leaving, the team disassembled the robot and each packed part of it into their luggage to avoid the costly shipping charges. For a team that is concerned about expenses, the prize money is a big incentive.
“Building a robot from scratch is a pretty expensive venture. So if we can win some money at the competition, then we can concentrate more on the engineering and the project itself,” said Billy Edwards, Mars Rover team leader and junior in mechanical engineering. The money would go towards scholarships, projects, and supplies for the lab.
During the challenge, the robot must work on its own to find a specific object in a park and return it to a designated point. The autonomous robot is guided by a computer program, and the team members are not allowed to control it during the task. The idea is to simulate conditions on Mars where GPS is not available, so the robot navigates by using cameras and other sensors.
“It’s really cool,” Edwards said. “It’s almost like seeing AI — to see something work on its own.”
The competition has two challenges. For the first challenge there is only one object to retrieve. Those robots that are successful compete in the second phase which has multiple objects. The week-long event also includes demonstrating the robot to the public.

Joining Edwards on the trip is Corwin Perren, electrical team lead, Lane Breneman, software team lead, Richard Cook, software senior design team member, and Erich Merrill, software senior design team member, all from the School of Electrical Engineering and Computer Science.
Beyond the prize money the team is excited about representing Oregon State.
“We want to show that OSU has successful teams and very good engineers. We want to show what we can do,” Edwards said.

The inaugural hardware weekend (HWeekend) at Oregon State gave 19 engineering students a taste of creating a prototype under time pressure. Six teams developed their ideas as far as they could in 30 hours, starting in the morning of May 31 and finishing June 1. Hosted by the School of Electrical Engineering and Computer Science the free event was sponsored by Eaton Corporation that provided hardware and food. Mentors from Eaton Corporation and Hewlett-Packard were on hand to help guide the projects.
“There are start-up weekends and app development weekends, but there wasn’t a program for something that covered the whole gamut of engineering, and included user experience. And I thought, ‘We can do that,’” said Don Heer, organizer of the event and instructor for the School of Electrical Engineering and Computer Science.
The theme for the weekend event was automation and non-obtrusive technology. Projects were as diverse as a moving trash can, and a cane for people who are visually impaired that would vibrate the handle when nearby objects were detected.
HWeekend participants had a “speed dating” session to get to know each other before forming teams.
The teams formed after having a chance to interact with each other one on one. Students with ideas for a project wrote them up on a white board and other students shopped around for a group. Cross-disciplinary groups formed with students from electrical and computer engineering, mechanical and industrial engineering, computer science and chemical and biological engineering.
Cory Rea, a power systems engineer for Eaton Corporation who served as a mentor, said the weekend was a great way for students to get some real-world experience.
“Every day in my job I work with a team across multiple disciplines — mechanical engineering, electrical engineering, sales, project managers. So, it’s important to be able to collaborate effectively,” he said.
Hannah Marvin, a freshman in electrical in computer engineering, said she came because she wanted to make connections with students outside her major. Marvin was a winner of one of the “Ironman Awards” given to 17 students who stuck it out the whole 30 hours.
“It went a lot faster than I perceived it would. It’s really cool looking at everybody else’s projects, so that makes it go by faster,” she said. And even after several hours with no sleep, she was still positive.
Ryan Skeele (mechanical engineering) and Soo-Hyn Yoo (computer science) show off their winning project.
“It’s really fun! Everyone should have a chance to do this,” she said.
It was a collaborative atmosphere where students helped out other teams when they could. One team stood out to win the “Helper Award.” Elliott Highfill, Travis Hodgin, Austin Hodgin, Max Schmidt, and Bradly Thissen worked on a project to play a game of tag with the TekBot robots, but were also a great help to the other teams by loaning tools, offering ideas, and help with coding.
The top award for execution went to a team that built a device to augment the function of a human arm as an aid for people with limited strength or other disabilities. Kyle Cesare, John Fritter, Ryan Skeele and Soo-Hyun Yoo intend to continue to work on the project which they hope to eventually be an exoskeleton suit including both arms and legs that can be easily reproduced by others without highly specialized equipment.
Heer hopes that events like these will show people how cool engineering is. “Engineers should be rock stars…they are the ones that make the world run,” he said.
Brian Benavidez, Arron Bellini, and Kamil Agrawala win the People’s Choice Award at Oregon State’s Engineering Expo.
The whirring sound of bike tires spinning on stationary stand could be heard throughout the Kelley Engineering Center as one after another Engineering Expo visitors tested out the Intellicycle. Based on the number of people flocking to get on the bike it was not surprising the senior design project won the People’s Choice Award. But it was more than senior Arron Bellini had anticipated.
“I wasn’t expecting more than passing glances, but then the interest in it blew up. It was pretty crazy,” Bellini said.
The Intellicycle is a device that can be added to any bike to measure speed, distance, cadence and temperature. The information is sent to a smartphone where it is displayed on a mobile application which can also bring up a map of your location. There are no worries about the phone running out of battery life, because the system harvests energy from the front wheel. In addition to recharging a phone, the power system runs the lights on the bike. But they are not just ordinary lights — these “smart” lights automatically turn on when it gets dark, and can also be controlled manually.
Brian Benavidez said he thought their project did well at Expo because it was very hands-on, it was easy for people to understand and useful to many types of bike riders. Having a bike situated in the atrium of Kelley was an amazing hook to get people interested. “We had a five-year-old riding it and an 82-year-old riding it, and they both had huge smiles on their faces,” he said.
Beyond seeing how fast they could get the bike to go, the visitors also had questions.
Benny Beaver tries out the Intellicycle.
“We had genuine questions from people who are not engineers wanting to know how it works. It was cool that we could take some complicated engineering and convert it into something that a 5-year-old kid wants to know about. It turned the competition into education,” Kamil Agrawala said.
The project, which was first hatched by the friends at a football game, split nicely into three parts they each had independent control over: the power system, the sensors, and the mobile application. The hard part, they all admitted, was getting the three separate parts to work together. And although they sometimes butted heads on how to get it to work, they left business behind them when they would hang out together as friends.
“The one thing I would tell other students doing their senior project, is pick a team that you have a good group chemistry with, because you’ll be working with these people for a year,” Agrawala said.
The many hours of work paid off in a project that captured the imaginations of those who visited, some who wondered if the group would turn it into a marketable product. For now, the success of finishing is enough.
“To come up with a plan and execute it the way we wanted to, and then to cap off with the award was a pretty monumental achievement. Right now I’m just feeling sincere gratification,” Bellini said.
Oregon State students Chris Vanderschuere, Carly Farr, and Bret Lorimore teamed up to create an app for the Corvallis Transit System to help bus riders track when their bus will arrive. Now available on iTunes, the app won the presentation award at OSU’s App Challenge on May 10. It was featured in The Daily Barometer and KEZI.
