Re: Section 8.3.3 Illegal Gearboxes and Chassis
Here is the question I posted to the Q&A forums although it has not shown up yet:

Quote:
My question is regarding Robot Rule R24 and how it applies given all the other rules in Section 8.3. I will first ask my question, then go into detail why I am confused regarding the rule and how it interacts with the other rules.

We want to use a machined aluminum gearbox housing that was designed and fabricated during the 2005 build season and used on our 2005 robot. We have not modified it since the 2005 season. According to rules R24 and R26, we should be able to use this component on our 2007 robot. Is this interpretation correct?

The part that has us confused is the last part of the rule which states "... IF they satisfy ALL of the rules associated with materials/parts use for the 2007 FIRST Robotics Competition."

What sections, exactly, contain the rules regarding materials/parts use? Is it section 8.3.4 only? Is it all of 8.3?

Robot Rule R17 seems to be in direct contradiction to R24. The 4th sentence of rule R17 states, "But absolutely no fabrication or assembly of any elements intended for the final robot is permitted prior to the Kickoff presentation"

R24 reads, "<R24> Individual COMPONENTS from ROBOTS entered in previous FIRST competitions may be used on 2007 ROBOTS IF they satisfy ALL of the rules associated with materials/parts use for the 2007 FIRST Robotics Competition. "

The definition of COMPONENT is, "A ROBOT part in its most basic configuration, which can not be disassembled without damaging or destroying the part, or altering its fundamental function."

Based on R24 and the definition of a COMPONENT, then my 2005 housing is legal, but based on R17 it is not. Please clarify.

Thanks,
Team 217
However, Tristan brings up a very good point regarding Rule R48. According to that, as it stand right now my gearbox housing is illegal to use. So, those of you worried about inspecting my team's robot; have no fear. Unless we hear concretely otherwise, we will design a new housing for our drive gearbox and use all new parts purchased / designed / fabricated after the start of Kickoff.

With that said, then why have rule R24? Commercial off the shelf components are covered every other place in the manual so why this special rule? It makes abosolutely no sense!.
