May I ask what motor and gear reduction you used for your intake/climber? You're using a CIM correct? I was really impressed with how fast the lift pulled your bot.

Glad you liked our robot! We really wanted to push ourselves to raise the bar on Ri3D this year. I leave whether we succeeded in that up to the community :)

I did answer the same question earlier in this thread, if you'd like more details than that, let me know!

Re: Ri3D 'Snow Problem 2017

My mistake, thanks for the info!

I would say you definitely succeeded on that front; this is only the second year I've kept up with RI3D, but your bot is probably the most impressive RI3D I've seen. I can easily imagine your bot winning a regional or district event and contending in World's (theoretically of course ).

Before I saw your reveal, I was pretty content with my team's progress, but now I'm anxious to make changes to our gear manipulator so it's perfect, and modify our climber so it climbs faster. I guess that's kinda the point of RI3D huh? To make us push our teams to the extent of their capabilities. So thanks for that! Haha

I have to ask about the wheels haha. To me they look like 6" Plaction Wheel with Blue Nitrile Tread (am-3316) if they are, how do you feel the wheels compare to the stock 6" white wheels?

You can find it with the rest of our white papers here.

When do you plan on having the CAD available for viewing?

They do use blue nitrile tread, but are actually 4" wheels.

Personally, I love blue nitrile. Always used it when I was on a team. That being said, it's definitely one of those marginal gains things. I would say that I feel it is better than the stock wheels in any way other than maintenance, but I don't really have any numbers to back that up. We used it on Lelantos because it matched our color scheme!

I'm aiming for next weekend or so. Our CAD was split up among about half a dozen people using all three of the main CAD packages available to teams, so I need to do a bit more cleanup than I've needed to do in the past. We're also still workibg on that technical walkthrough, which I'm hoping to get out tonight, but no promises on that.

Re: Ri3D 'Snow Problem 2017

Quick update: CAD is still coming, but school takes precedence over robotics stuff, so it'll be a few.

Due to a little bit of a communications mixup, we finished the technical walkthrough about a week ago and then promptly forgot to post it... sorry.

We've posted it now to our white papers . Best of luck to teams as you enter the home stretch, and if you have any further questions, feel free to reach out!
