Engineering World Health<\/h2>\n

Simple Solutions to Saving Lives<\/strong>
\nSometimes the solution to a big problem can be relatively small and simple. Take, for example, the defibrillator testers that members of the Johns Hopkins chapter of Engineering World Health<\/a> are building as part of the group\u2019s mission to deliver medical equipment and expertise to underserved nations.<\/p>\n

The 4-by-3-inch rectangles of hard black plastic arrive in pieces, their LED lights, wires, and circuit boards in need of an hour\u2019s worth of soldering and assembly. The completed testers are distributed to hospitals in a handful of developing nations including Honduras, Costa Rica, and Tanzania to assess the function of the lifesaving medical device used to treat cardiac patients. Though small, the devices, which aren\u2019t widely available in these countries, can make a huge impact.<\/p>\n

\u201cThese testers are really important because they can help save lives,\u201d says Danielle Dorfman \u201911, a biomedical engineering major and founding member of the group. \u201cHere we are at Johns Hopkins, home to the best hospital in the country and in the world. We know we have the resources to make a difference in these hospitals and that\u2019s just what we hope to do.\u201d<\/p>\n

EWH-JHU, which was founded in Spring 2008, plans to assemble at least 100 of the testers this year. But that\u2019s not their only focus. Members are also working to establish a relationship with local hospitals so they can volunteer in the clinical engineering department fixing broken medical equipment. With that knowledge, the students hope to repair the broken medical equipment they\u2019ve collected over the past year and send it to hospitals overseas. And the students just submitted a proposal for EWH\u2019s national design competition to build a manually powered otoscope for use in developing countries where external power sources are inadequate and batteries are not in large supply. Otoscopes, which are used to look into the ears and diagnose ear infections, are not widely available in medical facilities in developing nations, where undetected chronic ear infections are a major cause of hearing impairment.<\/p>\n

\u201cIn the United States we have all of the medical equipment we need, but it wouldn\u2019t necessarily fit in the environments in the developing world,\u201d explains Brian Keeley \u201911, a biomedical engineering major who is president of the chapter. \u201cIt might be too technical, require too much power, or be too expensive. What we want to do is come up with a simpler design that\u2019s cheaper to manufacture and easier to use.\u201d Although many of the group\u2019s 30 members are biomedical engineering majors, their reasons for joining vary. Freshman Manjima Dhar says she wanted to see firsthand how engineering and medicine worked together. What drew Zachary Patterson \u201913 was a desire to help people in need. \u201cThis is just a great opportunity to serve people who are so often neglected,\u201d he says.<\/p>\n

Engineering World Health members say they learn each day of another need for medical supplies and equipment overseas, which strengthens their resolve to help. Not too long ago, Rabia Karani \u201913 had such an experience when she told her family about her work with the group. One of her uncles, who works in a hospital in Pakistan, was especially excited about Karani\u2019s involvement in addressing health disparities and emailed her a short list of some basic items like centrifuges that his hospital lacks and desperately needs. She can\u2019t wait to help. \u201cWhen you think of all of the luxuries we have in American hospitals that people don\u2019t have elsewhere, it just really opens your eyes,\u201d she says.<\/p>\n


\n\"HUES1\"<\/a><\/p>\n

Hopkins Undergraduate Engineering Society<\/h2>\n

Connections That Stick<\/strong>
\nIt\u2019s called the \u201cTower of Power Half Hour\u201d and the rules are simple: Take a box of spaghetti and two bags of large marshmallows. Then, working as part of a team of five, build the tallest free-standing structure you can in just 30 minutes. No glue, no scissors, no additional building materials are allowed. And if the tower collapses before a student judge can get an accurate measurement, you\u2019re out.<\/p>\n

When the Johns Hopkins Undergraduate Engineering Society (HUES) debuted the wacky, sticky contest in February 2008 as a kick-off event to Engineers Week, the group hoped to field 10 teams. They got 39. The winning structure measured five-plus feet, won its team of engineers a couple of $50 gift cards, and spawned what has now become a much-loved annual event. It also did something else: brought students\u2014and even alumni\u2014from across the Whiting School of Engineering together.<\/p>\n

\u201cIt\u2019s just fun to be part of something that brings people together who normally wouldn\u2019t be together,\u201d says Max Rich \u201910, a biomedical engineering and math major. Rich is a founding member of the group and says the Tower of Power Half Hour will return to campus in February for its third year. \u201cYou can take the time to get away from classes. You don\u2019t have to stress out about it. Anytime that you get to interact with your peers and work on solving problems with an interdisciplinary perspective is just great.\u201d<\/p>\n

There is no dearth of clubs for undergraduates at the Whiting School of Engineering. But what struck Lee Ouyang \u201910 not long after he arrived on campus was that many of the clubs were aimed at particular majors or areas of study. \u201cSome of us thought the groups on campus were a little too narrow,\u201d says Ouyang, who founded HUES in 2007 and is co-president with Stephen Reilly \u201910. \u201cWe just wanted to bring people together to learn about engineering and have fun doing engineering projects.\u201d<\/p>\n

HUES member Julie Fogarty \u201910, a civil engineering major, joined the group as a sophomore. \u201cOnce you move into upper-level courses specific to your major, it\u2019s easy to get disconnected from the engineering community as a whole,\u201d says Fogarty. \u201cWhile the administration attempts to foster interdepartmental interaction through the Whiting School semester picnics and Engineers Week in the spring, HUES specifically targets students through competitions and community service to make an engineering student\u2019s experience at Hopkins more wellrounded and enjoyable.\u201d<\/p>\n

The group, which has 300 students on its mailing list, isn\u2019t just about fun and games (although the Engineering Carnival the group sponsored last year with other Whiting School student groups was a big hit). The group works closely with the Career Center to help promote workshops and job opportunities to specific engineering majors. There\u2019s an annual day of service. And HUES is hoping to sponsor its first Undergraduate Research Conference in the spring semester. \u201cThere\u2019s so much engineering research being done at Hopkins,\u201d Ouyang says. \u201cWe just wanted to showcase some of the work and highlight projects that might not be far enough along to be accepted by a large conference.\u201d<\/p>\n


\n\"Robotics_club1\"<\/a><\/p>\n

Johns Hopkins Robotics Team<\/h2>\n

Creativity Unleashed<\/strong>
\nAndrew Rohland \u201912 always assumed there would be an undergraduate robotics team at Johns Hopkins. After all, the university is home to one of the premier robotics and computer sensing research groups in the world. And Rohland, whose Southern Maryland high school\u2019s robotics team made it to the national finals in the Georgia Dome, figured there would be lots of like-minded students at the Whiting School of Engineering\u2014classmates who enjoyed the challenge of working together to build and program robots and compete against teams from other schools for cash prizes and bragging rights.<\/p>\n

But when he arrived on campus in Fall 2008, the mechanical engineering major learned that the university hadn\u2019t had a robotics team in years. So he decided to start one. \u201cRobotics gives students practice for \u2018real world\u2019 engineering and hopefully might even bring professors and undergraduates together for research opportunities,\u201d says Rohland \u201912. \u201cI think a lot of students at Hopkins want to be in an extracurricular activity that is related to their field of study and more companies are looking for that as well.\u201d<\/p>\n

Rohland was surprised when 40 students who share his love for robotics joined the new team this fall. Faculty advisor and computer science professor Gregory Hager was surprised, too, but also pleased since he knows the experience allows undergraduates to draw on their knowledge of mechanical and electrical engineering, computer science, math, and physics and gain valuable experience. \u201cThe hands-on experience students get in the Robotics Team<\/a> is as different from what they do in class as doing a thesis is from doing homework,\u201d Hager says. \u201cThey get creative opportunities to collaborate and pool what they know to develop a complete system, then see it in action.\u201d<\/p>\n

On a recent evening, team members met in the Laboratory for Computational Sensing and Robotics to work on designs for two of the three competitions they plan to participate in this year. One group, led by Venkatesh Srinivas \u201909, deliberated over the number of thrusters to buy for their entry for an Autonomous Underwater Vehicle competition sponsored by AUVSI (Association for Unmanned Vehicle Systems International). Their vehicle must perform a series of tasks underwater and the more thrusters they use, the easier the submarine will be to control. Despite having only $1,000 in their budget at the moment, the group decided to buy three thrusters, increase their fundraising, and cut back on their future pizza ordering. \u201cParticipating in these competitions is fun because you get to play with stuff that you hear about but you don\u2019t understand until you actually do it,\u201d Srinivas says.<\/p>\n

Meanwhile, freshman Sinan Ozdemir led the second group in designing an entry for the AUVSI International Aerial Robotics Competition (IARC). Their task: To create a fully autonomous helicopter that can navigate a building, drop the flash drive it is carrying and pick up another, and avoid detection by laser trip wires. Their secret weapon? Sonar. \u201cWe\u2019re not sure anyone has ever used sonar before,\u201d says Ozdemir, a computer science major. \u201cIt\u2019s a really cool idea that will get everyone\u2019s attention. Even if we don\u2019t win, people will remember it.\u201d<\/p>\n

Rohland is already thinking beyond the competitions, however. \u201cIt would be neat to have a robotic tour guide at Hopkins,\u201d he says. \u201cI know we could do it.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
