I think everyone knows this rule is not one I agree with, however it was voted on, and a majority of Roboteers agreed with it and so like all rules it should be observed.
It dose put both Spiderbot and Pilgrim in the cambot category but they are not fighting robots so it doesn't matter.

The rule is from my perspective too restricting, to make a mechanism that has 2 degrees of movement and would stand up to the fighting environment is almost impossible, to those that would differ on this point my response is obvious, show me one example of a mechanism that would satisfy the requirements of this rule, that has won a fighting robots type fight!
Perhaps there is one but I can't think of one example.

The rule of double the weight for walkers has scared people into making a rule set that is in practice impossible to successfully satisfy. my justification for the statement is based on the number of fighting walkers on the robot scene today.

I have come to terms with the notion that competitive walking fighting robots are not going to happen, and I am satisfied with the ones I have.

With life in general things don't always happen the way you would like, some things you can change and others you can't, peace of mind comes when you learn to discern the difference.

This is an argument lost and I am happy to acknowledge the fact.
