I saw this rule but I did not read this as a cannot. I just read it as a permissive rule--i.e., you can avoid putting bumpers on up to 1/3rd of your bot.

Suppose you had a chassis like this:



Are you saying that you cannot put bumpers on the inside (i.e. the concave) part of the chassis?

Or (and I do apologize for the crudeness of my drawings here),


You're saying that the bumpers in green are legal and the bumpers in red are illegal? Because the way I had read the rule was that the bumpers in green were necessary and legal but the bumpers in red were superfluous but legal.

Or am I misreading you entirely and you're simply making sure that teams know they need to protect 2/3rds NOT of the outside of their robot, but rather 2/3rds of the imaginary line described by the vertices of their robot?
