Walking Mechanisms Rules

[Eventorizon]

In the FRA rules it says that any walker's legs must have at least two axis of motion. In the ant weight class though lots of machines that are said to be walkers are actually shuffle bots.

If someone were to build a walker for the featherweights would people insist on the 2 axis rule or would people not mind a shufflebot?

I am actually thinking of making it in wood first to test everything out. It would be far to expensive to do it in metal straight off! Perfect for the new wooden class :-)

I think shuffle bots are allowed, you just don't get the same weight advantage.

[typhoon_driver]

well if you were just building a machine for fun fights at heavy events then i can't see anyone minding however I would have an issue if someone built a shuffle bot with the full walker weight advantage and entered it in the featherweight champs.

[Eventorizon]

Eventually I would want to enter it into the championships at the full 27.2Kg but as long as it can get used in whiteboards and non-competition events I don't mind.

The idea is to base it in Anarchy's walking mechanism (Or Scuttle) to take in both axis of movement, but it would be a ling time before it ever got built in metal!

It would be very wrong to give a 100% weight advantage for a shuffle mechanism, maybe around 25% or something like I think some American competitions do

[leorcc]

For a competition I would be dead against giving robots a weight advantage because it uses wonky wheels.

I think that that should be allowed the full weight advantage. You would need it to make it effective. I think as long as the foot doesn't spin 360 degrees like a wheel (or an off centred one) i think shufflers are only shufflers if they rest on some static feet (or the base of the robot) during some point in the walking gate. I would have thought that even if you put a foot that is kept vertical (ish) and then is moved in a circular motion by a crank should be alowed. As long as it has enough of them so it doesn't rest on its base. What do other people think? Because I think there should be more unique designs.

Is this a shufflebot?

It's based on .

[Eventorizon]

I would class that as a shuffle machine as it places the main body on the ground to make a step. A walkers legs, by the FRA rules, must have 2 axis or more of motion, that only has 1. Same with clawed hopper. the way they got round it was my not having 2 independant walking mechanisms on each side relying on the turntable to steer the robot.

This american bot runs on the same shuffle system as Clawed Hopper but as it uses 6 shuffling feet on each side so its more like a tracked vehicle than a walker. And again it only has one axis of motion = shufflebot. The same goes for the original Son Of Whyachi with its shuffling pads.
