so what would be actually classed as a true walker?

[calumco]

I no its most likely been discussed before, but am i right in thinking that anarchy off rw series 6 wouldnt be classed as a walker anymore?

Are there any examples about which would be ok and allow the double weight limit

Cheers for now

[typhoon_driver]

2 independent axis of movement on each leg (must be able to demonstrate both axis independently) and it must hold it's entire weight at all times

[typhoon_driver]

Wow I didn't realize I'd kill this conversation so quickly!

[calumco]

Haha,

so something like craigs walking spider thingy, is that mechanusm classed as a true walker? Id say yes?

[leorcc]

Actually no, because although it looks really good, it is in fact 1 crankshaft supplying the movement so it cant perform 1 axis independently.

[calumco]

Talk about making it difficult! I see that as a walker thou so you can see my confusion lol, do you no of any good examples/robots out there that are a walker

Thanks for your comments all the way from Oz.

No walkers fighting ever again! so let's stop the thread.

The legs need lateral motion as well as vertical motion.

[typhoon_driver]

Well if you want a full 100% extra weight allowance against other machines then it shouldn't be easy!

It's wrong to think about it as a vertical and lateral motion problem as Craigs machine actually has both movements. You should think about it as axis of motion. Nothing wrong with using crank mechanisms however because there is only a single mechanism, it can't have 2 seperate axis.

For a true walker you need to have 2 demonstratable axis that are completely independent of one another. It then becomes a challenge syncronising these two axis to give you the walking motion.

"Each leg must have at least 2 degrees of freedom"

I'm not sure if the actual wording of the rules has changed since I last looked, but I remember it sounding a lot more complicated than that. The ambiguity is still there though I would say. Would two degrees of freedom mean independent from each other leg or two degrees of freedom combined? I would say Pilgrim fulfilled that, i'm not sure about Spiderbot though, its been a while since I looked at it.
