Nice work 1345.

We will be climbing that ramp thats for sure.

Keep up the good work.


As for the Florida Regional , yes it WILL be insane

[Josh Murphy]

Looks good!!! I have some questions since you have tested yours already.

How grippy is the lexan cover? is it slippery or does it give them more traction?

[Dan Richardson]

Wowza, looks sharp great job guys.

My only question is that that looks like quite a bit deflection in your cross members of your ramp.

Have you done any calculations or measurements to see how close you are to the edge of where yielding will occur? I would hate to see it begin to form itself into an unusable shape ( then again you can always replace it if or when that happens )

Also, did you drive the bot up the ramp or place it there? I'm kind of curious to how well that polycarb ( or acrylic? ) holds up when a robot kind of slams into it.

It looks solid tho maybe its just the angle of the picture that looks like its causing that deflection. Maybe run some calc or even easier just some bench tests to see how when the dynamic loading / impact force of the robot running into and driving up the ramp will effect the integrity of those cross members.

I'm sure you've already been beeting the heck of it hehe but just a reminder.

Looks great, I'm deffinately gonna be scared to play you guys at UCF!

[Brad Voracek]

You guys plan to only have one ramp?

My mentor is trying to convince us, if we're overweight, to remove one drive motor on each side (right now we have two per side). I say we remove one of the ramps... We'll be better defensive, and we have a good manipulator. The ramp(s) will just help us get to the finals... then scoring should allow us to win. At least that's how I view it =/.

[Arefin Bari]

Team 1029, yes, there will be some kind of guard rail once we get the whole ramp working.

Josh, it's lexan. I wouldn't say its very grippy, but our last year's robot had no problem climbing up that ramp. If traction becomes a problem, we will put some stair tread on it.

Dan, yes, there is a bit of deflection in the back, if it collapse anywhere, it would collapse in the back. The plan is to have U shaped legs for supports instead of just one 1x1. Ran some calculations and it will hold atleast 180 pounds. I don't think anybody's bot will be more than 150. We drove the robot up the ramp, not place the robot on it. We ran into the ramp full speed (which was probably about 7/8 fps) and with 2" of clearance (last year's robot), the robot didn't have any problem getting up the ramp. Dan, you already know how much I beat the crap out of the robot during build, so it doesn't break during regionals.

David, you guys are welcome to climb up our ramp. =)

Brad, we will have two ramps. One on each side. Students just build one of them yesterday, so we could test it out. We should have the other one done very soon. Stay tuned.

What is the material on your ramp made out of? Is it polycarb?

[GVDrummer]

looks nice!!!

[Rohith Surampudi]

that looks sweet

A quick google search also says that polycarb is the same as lexan, that lexan is just a brand name for it.

[Eric Scheuing]

The arm reminds me a lot of the 177 bot from '05. Huge sprocket on top FTW.

[enpurx]

We have nearly the exact same ramp setup as you guys (one ramp on each side and same metal supports but with crossbars supporting the legs), but we can't figure out how to deploy them. We've tried different methods, but our rookie brains are stuck. Any help would be appreciated.

Thanks!
