Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Welding is being done by Isaiah and Tom
Hope to begin testing next week with unloaded cabinet over tile, carpet, and concrete
Back plate status: will be added onto design after platform is welded
Added in rubber caps for the leg edges
Accomplishments from Previous Week
Machining and welding progress was made
Still need to weld platform and attach back brace
Goals for Next Week (list names after each item). Use specific and measurable objectives.
New back plate - Ravi
Testing of the powered mover with and without the unloaded cabinet - all
Set up obstacles (tile, carpet, etc) - Pegah and Michael
Report by all: see the final section
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Have 2 straps (one on top and one as low as possible
Wants a more professional looking brace that can be welded rather than bolted
Consider sharp edges of the legs. Soften the edges or add a cap
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Delson's suggestions for the brace:
1. bolt it in and don't care about aesthetics
2. try to make the connection of tubes look prettier
-CNC metal to fit around the pieces, etc.
3. weld tubes onto the back brace and slide 80/20 onto it and bolt it on
Twisting of handle and ramp velocity analysis - Nathan
To avoid twisting of the brace tubes, Delson suggests using wider tubes, even wider than 3 inches.
He likes the idea of capping the tubes
Risks and Areas of Concern
Structural:
Ensure the platform and legs are strong enough
Ensure the linkage and bearings inside linkage function properly under full loading: analysis
Operation:
Ensure tipping is not a possibility by reducing acceleration / top speed of the unit : analysis
Ensure all clearance dimensions are met
Ensure cabinet is strapped in and secured: testing
Ensure cabinet is not scratched / damaged by unit: design
Schedule
Machining and welding this week
Testing next week!!!!
Budget (list amount spent and amount remaining)
4200 truck, 143 wheels, 1500 steel, hardware, and extra purchases , 1200 waterjet cut. $5000 remaining.
Progress on Report and Webpage
Evin - add onto old analysis, analysis of performance
Nathan - ramp tipping analysis
Pegah - make edits according to Mike's comments on the first draft, testing
Michael - executive summary, budget
Ravi - fabrication
Operation manual, conclusions, recommendations - to be done later
