Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Initial prototype design completed
The prototype was constructed from existing lab equipment and was used to gain a better understand of the of what we would like the final design to be. It was also used to test image subtraction code and helped to determine the type of camera lens that would be needed.
We are currently in the process of researching display materials, method of projection, and wing edge detection.
Accomplishments from Previous Week
Used preliminary setup of assembly to test image subtraction on a tethered fly. This was not optimal but was used to confirm proper operation.
Sent risk reduction presentation to sponsor. He commented that it looked good overall and that he believed we were demonstrating a good grasp of the overall project.
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Continue Research and Design of the Test Bed - James & Dean
Begin/continue testing display materials with existing lab parts. -James & Dean
Begin/continue testing method of projecting. -James & Dean
Start working on developing the code to measure the amplitude of the fly wing - James & Randy
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
During the last meeting our sponsor that although our preliminary design, see design process tab, would work for the time being, he did not like the fact that all the components, such as the camera, IR light, micro-manipulator, and display sphere were all connected to a single mounting pole. This made the whole system somewhat cumbersome to use and meant that bumping that one main stand could result in misaligning instruments. To remedy this, we along with our sponsor decided to go with a more modular assembly. This meant that most major components would be held by their own stand, thus making the assembly less cumbersome to use. We have yet to construct a CAD model, but coming to this agreement with our sponsor will guide any further design decisions. (3-11-14) (Sponsor's concerns were expressed in person)
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person
In our last meeting with the instructor, he expressed concerns regarding lag in the image processing routine. In our risk reduction presentation we attempted to address those concerns. Unfortunately, our methodology was cumbersome and lacked a clear example. Upon further research though, it was discovered that open CV has a built in function that can be used to keep track of the processed frames and actual frames so they can be compared and any lag can be determined. (3-19-14) (Instructor's comments were make in in person and in writing during risk reduction presentations)
Comments where also make in regards to more clearly demonstrating the work we, as a team, had done vs. what others had done. That was not our intentions to bluer this line and we will definitely make sure to better document and explain future work. (3-19-14) (Instructor's comments were make in in person and in writing during risk reduction presentations)
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
We had many comments from student after the risk reduction presentation via note cards.
These comments ranged from concerns about fly tethering to whether we should use the projector to project from the front of the sphere or from behind. These are all issues we are working on, but it was nice to see comments from the class.
All comments were make in writing after risk reduction presentation. (3-19-14)
Risks and Areas of Concern
Finding a display sphere that meets the design criterion.
Finding a display material for the projector(s) to display on.
How to display on the sphere.
Lag in the possessing code.
Resources or Information Required but not Available
The items above are resources and information that is needed, but we are currently in the process of researching them and making decision about them.
Schedule
Determine a method for projecting on to the display sphere. Testing will begin this/next week.
Confirm and order a sphere that fits design requirements. Research in progress.
Implement wing edge detecting routine. Programming will begin this/next week.
Developing and or fining a mounting system for the display sphere.
