The Dreaded Group Project

By Joe Bridgeman

Group projects in high school taught me one thing: trust no one. It seemed that every group member’s goal was to do the least amount of work possible and leave it to the select few who cared enough about their grade to take on the extra work.

Unfortunately, group work is very common for end-of-the-semester projects for many majors in college.

Fortunately, your group members in these projects are much less interested in backstabbing you than in high school.

I’m currently taking a computer science class, and our end-of-the-semester project is to create our own version of Tetris on the computer. I ended up in a group with five others and wondered how we were going to manage six different people with differing ideas and how we were going to split up our work separately and equally between all six.

A lot of Baylor professors assign group work at the end of the semester because it forces those with leadership qualities to take charge and teaches each student how to collaborate with others – a skill that will be put to the test often out in the work force.

Back to my six-person group saga; it turned out that two of the students on our group list had dropped the class, which reduced the group size to four. We met up, tossed out all of our ideas and decided on the best ones. I was happy to find that each group member seemed genuinely willing to do their part, and there were no issues in getting everyone to do their fair share of work.  I guess that’s the benefit of working with adults – there is a concern for the welfare and grade of the entire group, rather than a selfish drive to do as little as possible.

Don’t fear the group work in college! You’ll need those collaborative skills in the workforce, and unlike high school, everyone is not out to get you.

Engineers Gone Wild! (by Sophia Cooper)

Have you ever seen a bunch of engineering nerds yelling at a balls being deposited into a funnel? No? You’re missing out!

The Fall 2012 Junior Design competition was on Thursday afternoon. An entire semester of hard work, late nights, and trips to Home Depot coming to a close. As described in my October 10 post, our design project was to get two balls into a funnel about 29” tall while knocking a third ball off the side of the funnel and into a receptacle.  Throughout the semester we worked on our design, modeling it in the 3D design program SolidWorks, running tests on what parts worked or needed fixes, and constructing the entire assembly. I’m so glad my dad taught me how to use power tools at a young age; using a handheld drill definitely came in handy, as did that drill press!

Wednesday night before the final showdown was stressful. We had a HallEffect sensor at the top of our scaffolding, comprised of a magnet that sensed when its field was disrupted by its sensor counterpart and coded to stop moving, technology decided to not cooperate. We soldered together a PerfBoard for our circuitry, added in a couple extra resistors because our voltage regulator was overheating due to too much current, and re-uploaded the code to our microcontroller. Thankfully, it was a success! With our sensor up and running yet again, a couple adjustments to the ball disposal on our box, and recreating the net to catch the falling ball, we were ready to go to competition!

My older sister came out to cheer us on during the competition and laughed the entire time at how serious our class regarding this project. It really was a bunch of engineers gathered in a circle, yelling at little machines and cheering when our project worked. Elizabeth Davis, the executive vice president and provost of Baylor, even came out to watch the hilarity! Points were given based on how fast your two balls got into the funnel and if you were able to knock the third ball off into your receptacle. My team got first in two rounds and tied for first in a third of the four preliminary rounds, advancing us to the finals!

The finals were stressful! We had a hiccup with our ball disposal system not releasing balls into the funnel, but that was fixed with some duct tape for the second round. Going into the fourth round of the finals, we knew we were going to either get third or fourth. Unfortunately for them, another team’s power supply wire came out from their breadboard so when the switch was pressed, nothing happened to their project. Team Pride Rock got third overall!!

This project, while a lot of work, was definitely one of the highlights of my engineering career so far. It was a very practical application of working with other engineering fields as our team was comprised of mechanical and electrical engineers, a skill that I will definitely use after graduation. We worked hard, competed even harder, but still had a blast and loved cheering on all the other teams. My favorite part of the entire project was not getting third place; it was seeing how creative and smart all of my classmates are as well. There were so many different ideas of how to meet the requirements set by the instructors, and they all worked great! Being an engineer is all about working with teammates to meet the goal set by your client, and this class was a great stepping stone to meeting the goals of our future employers.

When people call me a nerd, I embrace it.  I am literally obsessed with calculus, captivated by anything that flies, and want to work in the aviation design field after graduation.  One of my current favorite classes is my Junior Design course, a requirement for a major in mechanical engineering.  In a group of 6 students (three Electrical & Computer Engineering, three Mechanical Engineering), we are working to design a game based on specifications of our professors.

Not only do we have to work on our teamwork and communication skills, but we get to cultivate design skills as well.  Using the 3D designing program SolidWorks, my team has developed a system that fits the class requirements.

 

 

 

While the model looks complicated, the systems aren’t too bad!  We are required to raise two 1.25” balls up to a 29” tall funnel as well as knock a third ball from 20” off the ground to a circular receptacle on our base.  We created our idea based off sketches and brainstorming, then took to the computer lab where I modeled all of our ideas so we can get a visual representation and see how it will all fit together.  This class is taking over my life!

Our mechanical engineering part of the group was tasked with finding the correct motor that has enough torque and rpm to lift up our big box.  Doing plenty of research on websites such as RadioShack and McMaster-Carr led us to select a 24V, DC motor that will be wired using a Double Pull-Double Throw relay.  The models and schematics of the motor are shown below.

This stuff seems complicated and the words seem big, but with dedication and hard work it is so much fun!  I love being an engineer and getting to share with you, my readers, about why it is so awesome.  If you think that designing your own mechanical or electrical systems sounds cool, considering joining Baylor Engineering & Computer Science!  For more information on the department, click here or leave me a comment.
