There鈥檚 been an explosion at a local manufacturing plant that鈥檚 toppled over walls and collapsed portions of the roof. The fire department extinguished the fires and the rescue workers were able to get all but one employee out before the roof collapsed. The building鈥檚 been deemed unsafe and the rescue workers are scrambling to find a way to get the employee out of the building.
Your company, Rescue Robots Inc., received an emergency call requesting a robot that could enter the building and rescue the trapped employee.
鈥楻obot Rescue鈥� is the theme of this year鈥檚 20th Annual Electrical and Computer Engineering Design Competition. Students are asked to design the sensors and controllers that power the robot through the obstacle course so that no human interaction is needed. In other words, the robot must operate autonomously during the competition and employ whatever strategy the student has designed without interference.
The annual competition is part of Design Methods II (ECED 3901), a mandatory third-year engineering course where part of the class is devoted to theory while the other part is designing and building the actual robot. Students begin working on their robots in May and have three months to design, build and test them, all while managing a full course load.
Getting there
Despite the emphasis on the competition, the actual marks given out are based more of the process rather than the delivery.
鈥淗ow well they do in the competition is a very minor part of this whole thing. It鈥檚 how they get there that鈥檚 important,鈥� explains Sara Stout-Grandy, electrical engineering professor who鈥檚 overseeing the competition. 鈥淭hat鈥檚 why the bulk of their mark comes from the progress reports.鈥�
Students are required to complete two progress reports, a final report, and various assignments and labs detailing all aspects of the planning stages from design to delivery. They鈥檙e asked to record everything from project scheduling, brainstorming sessions and prototyping and submit it as a formal engineering progress report.
鈥淲e want students to treat these progress reports like a report for a customer in the real world. So theoretically, I鈥檓 the customer and they need to report to me with details on timeline, different stages the project went through, what was accomplished, problems that were encountered and how they were fixed.鈥�
Industry-driven
Dr. Stout-Grandy is a part-time instructor in the Faculty of Engineering and also works for GeoSprectrum Technologies Inc. The fact that she works in industry has become a huge asset to her students.
鈥淏ecause I work in industry, I know what鈥檚 expected. Any student can pick up a textbook and learn the circuits. But to build them, test them, and get the circuit to work multiple times and under pressure is the real test. It requires integration, system testing and knowing how to join functions together and how to test them and backtrack when mistakes are made. It鈥檚 a huge skill, one that I use everyday in the workplace and this is what I want to convey to students.鈥�
Dr. Stout-Grandy graduated from the Faculty of Engineering (formally TUNS) and was taught by Peter Gregson 鈥� the mastermind behind the robot competition. If fact, it was the聽 1996 incarnation of the robot competition that inspired Dr. Stout-Grandy to enroll in the electrical engineering program. 聽
鈥淟ooking back, Dr. Gregson was so ahead of the times in terms of this competition. It鈥檚 progressed quite a bit to keep up with industry standards but the focus on proper design approach and hands-on problem solving remains.鈥�
Spirit of collaboration
Although professors are on-hand to answer questions and help work out ideas, students agree there鈥檚 no hand-holding in this competition.
鈥淚t鈥檚 like, 鈥榟ere鈥檚 a kit, here are the requirements, have fun.鈥� So at the end, we turn the robots on and hope for the best,鈥� laughs electrical engineering student Kathleen Svendsen.
Some students are working in pairs while others opted to work solo. Either way, there鈥檚 usually always someone around to bounce ideas off of.
鈥淭he competitive aspect of this project is pretty mild,鈥� explains Matt Duffy, third-year engineering student. 鈥淲e鈥檙e all friends and we鈥檙e all here working in the labs for hours on end. We help each other out when we can.鈥�
The strategies for each team vary. Some choose to focus on distance sensors and light sensors while others are building wall crawlers.
For Moteb Alsumiry, he鈥檚 decided to use a combination of distance sensors, light sensors and touch sensors, all while keeping in mind one important thing: motor control.
鈥淲e were told by former students that one important thing to keep in mind early on is motor control because sometimes the biggest challenge can be just getting off the starting block,鈥� he explains.
The fictional manufacturing plant is represented by a surface that鈥檚 28 feet long by 16 feet wide. The surface is made up of fixed walls, destructible walls, moving doors and several other obstacles that will remain a mystery until the competition is underway. At the far end of the surface, there is a flashing red light revealing where the trapped employee is.
The competition will be held of Wednesday, July 20 at the Sexton Gym at 1360 Barrington Street. The finals begin at 6:00 p.m. and go until the last fictional employee is rescued.聽
