Looks pretty solid!

Re: pic: 6in Butterfly Module With Piston
might be nit picking here, but isn't a butterfly drive omni wheels as opposed to mecanum wheels?
|
Re: pic: 6in Butterfly Module With Piston
If you put omnis on it then you're not going to get much utility out of it. Really, what do you gain from switching between traction and omni? You turn a bit better. That's about it.
However, if you have mecanum wheels, you can switch between having insane push power, to having a fast and holonomic drive. You get more utility out of it this way. |

I'm not going to claim to be an expert on butterfly drive, but I wouldn't feel comfortable cantilevering that module out like it's a WCD, I'd rather support from both sides here. But then again I'm from the east coast...

Re: pic: 6in Butterfly Module With Piston
Back on topic and not debating the pros/cons of butterfly vs. mecanum, I have to agree with pmangels somewhat that cantilevering the module sounds quite risky.
I think this would have to be paired with some bulletproof bumpers or an outside rail in order to work super well. That being said, I love what you're trying to do, and I really wanna see it work. |
Re: pic: 6in Butterfly Module With Piston
How are you going to manufacture the bracket for the cylinder? it looks dove tail joint I would use for wood drawers.

That piston mount plate might bend over time, particularly if there are bumpers contacting it (shoving can get them). We had a similar issue with bumpers in 2014, but it depends on where your bumpers are vertically.

It's a cylinder, not a piston! <end Rant> |

But great post by you being actually objective! :) |

Interesting module, I would also like to see how cantilevering it works out. Make sure you test that before the season starts if you plan on having it as a possibility. |
Re: pic: 6in Butterfly Module With Piston
Two things,
First, I too am skeptical of cantilevering the module for stability. I have no doubt that the plates would be fine structurally but I could see where your wheels may want to bend the module and possibly loosen some of the bolts as well as not turn smoothly. Second, I assume the traction wheels are 3 in, am I right? I am certainly no expert on this kind of drive and the cantilever may perform wonderfully, I would just have to see in running to be in full support of cantilevering the module. I love the idea behind this sort of drive train and I would love to see a video and real life weight once you actually have it working. |
