Verification & Demonstration of Results
Table of Contents
Motion and buoyancy were tuned using the long tank in Dr. Gomes lab, and the fish was ultimately taken to the RIT swimming pool for quantification of final performance. Video was taken of the fish swimming and turning, which was analyzed in an open source video analysis software called Tracker to find the forward velocity and the turning radius. Screenshots from the analysis are shown below.
Final Performance vs. Specifications Matrix
Other engineering specifications were easier to measure, and all are shown in table below comparing the engineering specifications established during MSDI, with the values obtained.
The most important test was to demonstrate the final product during Imagine RIT. Both a booth with the final poster, and a 12-foot diameter swimming pool were set up as part of the exhibit, with Dr. Lamkin-Kennard providing the pool as well as a tent to keep the table and poster dry from the occasional showers. The poster and pictures of the swimming pool demo are shown below, and the showers didn't seem to hurt people's interest in the fish, as the pool could hardly be seen through the crowd of spectators for most of the day.
Customer DocumentationIn addition to submitting the design to design competitions (covered here), the final phase of Senior Design required completing documentation for the customer, demonstrating that the final product met the customer needs, and information necessary to use and maintain the product after the end of the course.
Proof of meeting the customer requirements was presented above, with the exception of the aesthetic aspects. Proof of making it "Look like a fish, move like a fish, and feel like a fish" was gotten by customer satisfaction, and by the numerous questions such as "Is that a real fish?" asked by visitors during ImagineRIT.
Quick overviews of the mechanical and electrical systems and how-to videos documenting how to use the fish and how to overcome common problems such as lines breaking or loosing Bluetooth connectivity were also recorded. These can be seen in the Owner's Manual Folder under Final Documents.
The last part of documentation was recording suggestions for future work, should a follow-on project to our be given to a future team. This included things that we would improve on our own project given additional time and resources, as well as things we learned while designing and building our system that we thought might be helpful. This was written up as a "letter to future teams."
The final presentation for the two semesters of Multidisciplinary Senior Design was conducted on May 8th, 2014. A PDF of the powerpoint presentation may be viewed here.
