Same here

And I actually think the walker weight limit rule was something that started in the early US competitions, but I could be wrong.

Well, I am a stubborn git and am keeping my tracked bots weight limit at 100kg

Do as you will Dave.

Tracks & Shufflers @ 100kg pleesums!

To easy to bend rules with these designs, so why give them the insentive to bend them!!

Proves my point even more. Was so easy to bend the rules and get that design in. One of my other rule bending designs was a robot that was a walker and a wheeled robot. Would start the battle as a slow 5MPH walker, then flip itself over and drive around as a 20MPH wheeled bot @ 150-200kg... 50kg flywheel FTW

Another good example is Blizzard... Screw drives are effectively another form of omniwheels... Yet, bend the rules quiet nicely if I do say so myself :wink:

So youre not going to make MDU4.1 a 200kg walker again, as planned?

[knightrous]

Lol.
No, 1.0 was the last of the walking MDUs.
2.0 never left the paper (expanding rim design).
3.0 - 4.0 MDU series are translational spinners... More then likely, 4.1 will a cylindrical 2 wheel translational spinner, driven on series wound motors, with active adjustible teeth and a lot of Hardox....

Depend on my motor selection, it could end up as a 1 wheel translational spinner...

How exactly would that work?

Way cool...I think Ill just stick to wedges if I ever build something though

As to the tracks rule, I believe I was either the first to pitch it or the first to use it - I forget which.... anyway, there were and are several reasons:

Firstly, no one uses tracks, it was a way of encouraging more.

Secondly in vapourbots, however much exposed wheels arent treated fairly, tracks have traditionally had it twice as bad through merit that they need to be pretty exposed to function, so in my view the weight is justified.

Thirdly they are heavier, and there is more to go wrong. Also, bear in mind that they do not necessarily get better traction - in a wheeled bot the traction is improved because the weight is focused into a smaller area, by increasing the area you gain increased friction but decreased force per square inch against the ground (I think anyway)

Personally I dont intend to do so myself, but I can see the merit in increasing the weight bonus from 10kg to 25kg.

Only if you want your machine to be invertible.
