Revision as of 23:58, 18 June 2009
This page contains a week by week breakdown of what we did.
Contents
Kickoff
We attended the kickoff at Upper Darby HS where we were introduced to Lunacy via the NASA telecast from FIRST's New Hampshire headquarters.
Week One - Research and Brainstorm (1/3-1/10)
- Inventoried the Kit of Parts
- Researched previous designs in old FIRST Behind the Design books
- Discussed dumping versus shooting, benefits of rotating, etc
- Researched, tested, and analyzed Rover wheels' frictional coefficients
- Analyzed wide versus long chassis and 4 wheel versus 6 wheel drivetrain
- Settled on 6-wheel drive wide chassis, designed based on the hypothetical 2008 drive system, cut necessary pieces
- Began discussing fishtailing the trailer and perpendicular/pivot wheels
- Began designing Moon Rock pick-up system and Empty Cell holder (t-rex gripper)
- Began discussing heads-up display
- Welding practice
- Worked on building trailers
- Began developing meeting planning model
- Began discussing field-sharing with local teams

Week Two - Prototype and Chassis Fabrication (1/11-1/17)
- Welding practice
- Welded chassis
- Researched and prototyped spiral hopper with brushes
- Designed 7th Wheel
