We used the NASAs engineering design sheet to plan out what we needed to do to fix Rofl Bot. We defined a problem: THe Ball pen is broken becauser it has no net and it is floppy and looks like @#$%. We then defined constraints, we want to keep the weight as low as possibvle and keep everything within the robot dimentions. We made several sketches on the SMART board and are saved under a smart doc. I will put them on when I figure out how to. We already started the prototype phase, we used 30lb. test fishing line in place of metal wire. It was ridgid enough to continue on with that design. <br> | Mach. 1511: - (Group 2) Mike M., Becca and Jake Kremer, Shauna ~Mach. was at a demo, we worked on ROFl Bot, came up with a plan to fix the ball pen and to fix the panels.

Form groups for inventor and two repair groups (thunderplucker and mach1511)
Mach. 1511 team: ( Mike M., Kristina Kohl, Jacob Kremer) we marked the holes for the screws to reattach the drive train to the frame. We also brainstormed ideas fo reparing rofflebot. Next week we will drill out the iron bar and will finish up repairs on Mach.
Inventor group:
Sam L, Alex R and Chris H completed lessons 1 and 2 for inventor. We watched Alex W make a chain tensioner on Inventor. Alex explained the benefeits of using Inventor in the process. We then reviewed a prototype of the tensioner for how it would function on Mach 1511. Then we revised the model to reflect our findings.
ThunderPlucker:
Tony, Liz, Tresten, Shauna, Mike Hartman fixed the top spinner on Thunder Plucker and moved the motor. Replaced the missing or broken pluckers on the bottom roller. Moved belts back to where they belong (again...). "i think thats pretty much it..." -Tony
Robot Locations:
Mach. 1511, Trailor
Thunderplucker, Closet
Rofflebot, A-10
Trailer Key is in the closet.
11/4/2009
We went over the eight steps to the engineering process.
Mach. 1511: - (Group 2) Mike M., Becca and Jake Kremer, Shauna ~Mach. was at a demo, we worked on ROFl Bot, came up with a plan to fix the ball pen and to fix the panels. We used the NASAs engineering design sheet to plan out what we needed to do to fix Rofl Bot. We defined a problem: THe Ball pen is broken becauser it has no net and it is floppy and looks like @#$%. We then defined constraints, we want to keep the weight as low as possibvle and keep everything within the robot dimentions. We made several sketches on the SMART board and are saved under a smart doc. I will put them on when I figure out how to. We already started the prototype phase, we used 30lb. test fishing line in place of metal wire. It was ridgid enough to continue on with that design.
Goals:
R ~fix ballpen/net system
R ~reinforce side paneling
R ~reattach drivetrain
R ~make a new net system
R ~contact electrical subteam to see if we have conflicting ideas
thunder plucker:- Tony B, Lizzy M. find probloms that still exists and fix them.
Inventor team
Alex W, Sam L, Alex R, Chris H
Goals:
1. Learn Inventor
2. Finish chain tensioner
Robot Locations:

Leanne Attendence: Alex W., Sam L., Alex R., Chris H., Tony B., Lizzy M,.Mike M., Becca, Jake K., Shaunah, Mr. and Mrs. Wolf
11/18/09
1. On Thunder Plucker, we (Sam L, Alex R, and Chris H) removed broken a ball guide from the top of the shooter.
2. We tightened the bolts on the ball spring guides.
3. We discussed knuts and bolts and weldments and the importance of marking panels so that they would get replaced in the correct location.
4. We discussed measurements (callipers).

Completed lessons 1-3 and the unwritten lesson 4
Did random enrichment that Alex found on a desk called 2D quiz

ROFL Team: Chris H, Sam L, Alex R., MIke M., Kristina K.
We gathered around ROFL, brainstormed Ideas to make panels on ROFL. Decided on two options. 1) Wire mesh (as noted below) to cover sides. 2) Interwoven steel wire rope 1/32" Diametor (McMAster Carr Item No. 3498T41). WE researched viable options and found the materials.
