Team 968's 2009 Robot

[sanddrag]

I think it's amusing how it looks like a miniature vex-sized model sitting on the table in this photo.

We tested the urethane belting stretch extensively with a single-belt jig ofr each conveyor, before we got the robot built. 9% stretch seemed to be the magic number for us. However, by the time we put 10 of them on a roller, there's about 300 pounds of force pulling on it. Quite the stresses on the rollers, considering shear stress, torsional load, and bending moment. If we were to do it again, we might go with slightly less stretch.

We do not anticipate any inspector troubles with the robot. Everything complies with rules and GDC posts. The smaller frame member above the wheels is structural; we often use it to lift the robot.

We anticipate weighing in at approximately 8 pounds under the limit.

As an interesting note, I'd like to mention that we started the season with $11 (yes, eleven) to our team's name and no certain sponsors. Thanks to fundraising efforts and the generous contributions of our returning and new sponsors, we have arrived with what you see here.

I would also like to thank the members of team 254 for their countless hours of design, CAD, and manufacturing work that was put into this machine.
