FIRST 2015 Recycle Rush Question Involving Robot Extensions

[tabman247]

Our team today was discussing possible dimensions for the robot we are designing for this year's competition. While we were coming up with ideas, we realized that the game manual for this year doesn't specify maximum possible length allowed for extensions on the robot. According to the rules, it says:

The ROBOT must satisfy the following size constraints:
A. during a MATCH, the ROBOT height may not exceed 78 in.
B. the ROBOT must be able to be arranged into a TRANSPORT CONFIGURATION with dimensions which do not exceed 28 in. wide, 42 in. long, and 78 in. tall.

Does this mean that, following how size rules were in previous years, we are able to go beyond that 42 in. in length with an arm or something that comes out for a moment? I remember in past years, the rules would say something like "cannot exceed 6 in. in extensions from robot perimeter". With a rule like that "missing" from the rule book, do we have an infinite as physically possible amount to extend from our robot?
