I think you are right. I think you meant 30 kg which is even better at ~66 lbs. a wheel.

Every season as of late, we always cross paths with the Robonauts.
Being able to see the engineering behind their robot, competing both with and against them, and talking story with all of their mentors and students are always part of the highlights of my season (among other Texas teams).

I would have never guessed when the video was released that both 118 and 359 would team up in elims. Those semifinals matches in Curie were oh so close.

What is the "normal" drop on an 8wd system for the two center wheels? Is it around 0.100" like a 6 wd drive? Does anyone know what 118 did on this bot?

Chain in tube drive. so they have zero drop on the drive. Instead their outside wheels are smaller, no clue how much smaller though.

In 2013, I believe they ran the outer set of wheels without tread.
I would assume they either did the same thing this year, or used different sized wheels on outer vs inner axles.

I make this assumption based on the "Chain in Tube" method 118 used in 2013 and 2014. With 17t sprockets and #25 chain (2013 setup) there isn't much room at all inside the frame rail. This leads to altering the wheels.

Cool, thanks for the information.

In case anyone doesn't want to buy the rotacaster's from Australia, they have a distributor outside of Cincinnati. Kornylak Corporation

Plus the mechanum wheels they sell look an awful lot like Andymark mechanum's.

Is 118 releasing the cad on this like they have in the past on FRCDesigns.com?

I'm really interested in that drill gearbox assembly that you have on your shooter.

Like JohnFogarty, I'm interested in if Team 118 will be releasing the CAD to their 2014 robot. I briefly got to check it out at championships, but there is a wealth of knowledge in that machine that there is still to learn.

We're working to get the CAD posted.

I hope to have it up next week.

Until it's posted on our website...here is a direct link.

There are some details missing, but this is pretty complete. Enjoy.

Just out of curiosity how much use did the servo brakes see in competition?

JohnFogarty 08-07-2014 10:16
Re: The Robonauts 118 - 2014 Video
 
The brake and overall gearbox surprised me as well. Was the 5:1 reduction the final reduction..for real?
