Rules on use of Axe

**cidade** · 24th November 2008, 18:32

Hi there,

Iam quite a newby on this subject, so I would like to use your knowledge of robots and their weapons.

I thought of creating an huge axe on my bot, driven by a torsion spring. What do the rules say? I mean, how long can the axe be and are there any limitations to its sharpeness? What is the maximum of power such an axe may produce?

Thanks in advance!

There is no limit on anything for an axe except pneumatic operating pressure (1000PSI). If you can make it operate powerfully on a spring, make it sharp enough to split a hair, and as long as a limo, you go right ahead

Im a big fan of axes and Id love to see a new one

Hunter D1 was originally boing to be an axe, but the motor was so powerfull the gear had all of its teeth cleaned off!
I need help as well! :sad:

there is the size limit applyed to all robots of 1.2 metres in any direction.

Sharpness - i wouldnt make it to sharp, it will go blunt very quickly.

Wow, thanks for all your thoughts. I think it is possible to store a lot of energy into a torsened spring. Especially with a combustion engine with enough cc to use the maximum litres of gasoline (.5 litres I thought). Being a math student I tried finding the maximum amount of energy that could be stored into a spring mechanism. Any physicans around here to answer this question?

And by the way, I do live in Holland.

A very sharp, powerful axe will make you very unpopular! At the live events its about scoring points to win not destroying your fellow roboteers machines.
Terrorhurtz is a goog example, very powerful but it has a blunt, aluminium axe head and is used with a degree of compassion. (unless you start to beat it!)
