Overview of the Project:
Funds will be used to build small mechatronic systems in a cigar box that students can bring them home in their backpacks. The intended learning outcome is for students to gain hands-­‐on experience in the practical issues that are encountered when implementing controllers.
Final Report Fields
Project Objectives:
The objective of the project was for students
Project Achievements:
With 44 students in the course, I assigned 11 teams of 4 students, and each team was able to have their own take-home experiment. Each take-home experiment cost approximately $100 to build (motors, arduino controller, H-bridges, etc.) With the $500 from CRLT and $500 from the Assoc. Dean for undergraduate education, the ME department supplied the balance of the funds and the technician support to construct the boxes. It took a bit longer than expected to get all of the parts and assemble the boxes, students did not receive them until October 12th. The GSI for the course was incredibly helpful, and he felt that the students should have to wire up the boxes themselves, since it would help them in debugging any problems. Each team wrote a project proposal (before they had received their boxes), a midterm report, and a final report. Each team also did a presentation to the entire class during the last week of class. Overall the final projects were creative and well-implemented, making good use of the box as input and output, and integrating with Matlab/Simulink for visualization on the screen. One team developed a game of "pong" and another developed a football simulation of linebacker vs. lineman. Several teams chose to emulate automotive applications (active suspension, cruise control, etc.)Based on the student comments on the course evaluations, the project made a valuable contribution to the class and helped them connect what they learned in lecture to real-world implementations.
Continuation:
I gave the boxes to Prof. Brent Gillespie who used them when he taught ME 461 in Winter of 2012.
Dissemination:
The boxes will continue to be used in the dynamic systems and control courses within the ME department.
Advice to your Colleagues:
The GSI had a box, and I wish I had also had one for myself, so that I could have experimented with things that the students were struggling with.The next time I do something similar I will make up homework assignments to go along with the take-home experiment, and not leave everything to the project at the end of the term. It would also be good to find a way to make sure that each student has a chance to take home the experiment him/herself; I think in some teams, there was one student who did everything and the others didn't contribute (at least to the experimental part).I might consider asking each team to make a YouTube video instead of doing a presentation in class. There were some issues with the demos that they tried to do, which delayed the very packed schedule of presentations. It would be good experience for them to make a video and post it on-line.Technically, the linear slides that were used had very high friction, which turned out to be the dominant effect in the system (it was difficult to demonstrate the ideal first-order system model behavior with these boxes). A different configuration with a larger range of motion (perhaps rotary) might have a better match with the ideal model.
