Can you guys elaborate on your test setup for this??

Thanks

What durometer of polyurethane were you guys using? That looks soft enough that you could just peel it off if you wanted....

Re: pic: We got bored :)
 

I believe the orange colored urethane from banebots signifies a shore 30A durometer.

//its shore 40A see below

probably around 80lbs of weight on module, cordless drill powering it

Held the setup still and spun the wheel on carpet seeing how the wheels would handle it
after around 2 seconds stopped and this is the result

"Black PP Core, Medium Orange 40 Shore A TPR Tread" From the BaneBots website.

I wonder if the Blue 50 Shore A would do any better. Also, isn't 80 pounds a but much for one module?

Re: pic: We got bored :)
 

Yeah it is, but even then seeing it die in this fashion convinced us to no longer mess with the banebots wheels.
Kinda a safety factor test and they failed

Which Colson wheel do you plan on trying out?

Re: pic: We got bored :)
 

2"dia by 7/8" wide colsons

Thanks to all the folks from 1625 for showing everyone these pictures. Each new image brings new and "wonderful" surprises - I love it!!

Its not last years swerve module, its one of the original prototype tubes.

Re: pic: We got bored :)
 

WOW! How practical would that be? Considering the wheels shred easily... How did you guys get the chain length right on?

(From what I can see the 25 chain look pretty taught...)

It's not terribly hard to do if you have CAD. You can find the size of a link pretty easily, giving you a unit that we'll call one link. You find the exact wrap around the sprockets, which gives you a certain distance (x links, we'll call it). Then you find the exact distance between the wraps on both sides and get another distance (y links). Add x and y and you get the number of links needed. If there is a fraction less than 0.5, add a half-link (special link); if there is a fraction between 0.5 and 1.0, add one link. Make your chain that number of links long, put it on, and you shouldn't have to worry about tensioning for a while.

We are currently working on a different setup incorperating colson wheels http://www.robotmarketplace.com/prod...on_wheels.html. The reason we originally went with the banebots wheels is because they come with a half inch hex in them.

Any updates? I think it'd be cool to see these orange-anodized ...
