Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Currently working on first prototype, all parts and materials are available, need to finish 3D printing new chassis
Conducting analysis of spring stiffness for the cart for linear view along bore and back view
Accomplishments from Previous Week
Printed first cart chassis and learned a great deal about improvements that need to be made: increasing wall thickness, lowering roller location to have more clearance over forcing cone, and the difficult of press fitting bearings into 3D printed material
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Operate laser and take high resolution pictures with Beaglebone: Arman
Work on gear alignment and driving rollers with motor: Daniel
Implement motor characteristics into Workingmodel and determine the optimum spring constant: Sina
Work on making suspension rollers move smoothly with a small amount of friction: Danny and Cesear
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Sponsors are happy with design and want to see working prototype by this Friday, May 1st.
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Define areas of risk more accurately (see below)
Use working model to show that if the top roller becomes offset, it will correct itself: Sina has completed an example of this
Risks and Areas of Concern
Will the cart drive straight? will it tip the side at all
Analyzing camera resolution? Spec sheet says camera is high resolution but picture collected does not seem as high
If slip occurs can we accurately show this for data analyzation?
Operating camera, laser, and motors accurately with microcontroller
Schedule
Finalize first prototype: Friday, May 1st
Test prototype and collect data: Friday, May 1st
Finalize proof of concept presentation: Monday, May 4th
Budget (list amount spent and amount remaining)
Progress on Report and Webpage
Working on first draft of report, due this Friday, May 1st
Cleaning up webpage and adding important information
