Re: pic: 141 rendering with ramps down

Ok. Im going to be honest. Cool, i think its unique.

But do you really need FOUR (4) ramps? many teams had one, and did ok. More have two, and i can understand that (two entry points for two different robots). But i simply dont understand why 4 ramps are worthwhile. Are some stronger than the others, or what?????

I think there are four ramps so other robots have a choice, say if one side of the ramp is blocked they can still climb up on the other side, and if it is just more convinent etc etc.

WOW...

That's one BEAUTIFUL bot! I presume it's made to hold 2 robots 12" high....

So, a few quick questions.

First: What is the angle of incline on your ramps?
Second: Could you give us some specks of your drivetrain?
Third: It seems like you can score on all 3 levels, but how easy is it to score on them (especially the middle one, based on your rendering, unless it has one last pivot that I am not seeing, it seems that may be most difficult).
Fourth: Which side do you pick up ringers from? (the side with the ramps or without?)

<EDIT> more questions ^.^
Fifth: Does anything protect your arm device from being hit by robots coming onto your ramps?
Sixth: How long does it take for you to deploy your ramps?
</EDIT>

Overall, it's one of the nicest looking bots all year, good job!

Re: pic: 141 rendering with ramps down

The drivers wanted the ramps to be as user friendly as possible. They could easly see last second ditches for the ramp (gotta place that spoiler) coming from the rack and needing a high speed direct from the floor approach. However, one good defending bot could probably cause enough problems to keep a robot from getting up directly (straight in) from the field. The ramps to the side require a 90 degree turn and take more time and the only way to really defend them is for a robot to get penalty points. Because of the weight budget for the ramps, especially with four ramps and two parking spaces, support legs etc. the kids had to design a ramp without anything mechanical other than a secure release mechanism. I can remember the mentors standing there saying it could not be done (three folds, four including the leg support, using gravity), that is until a couple of the kids showed us how using cardboard mock ups. Before I forget, it takes less than two seconds to deploy all four ramps and the parking spaces.

How do yall get all the ramps to fall?

Re: pic: 141 rendering with ramps down

I realise i might havecome off as slightly hostile in my earlier post. If anyone took offense, i'm sorry.

two quick questions:
1. How do those things deploy? any video available?
2. Any chance at a view of the underside so that the ramp lovers out there can see your bracing?

Re: pic: 141 rendering with ramps down

wow, a lot more questions then i expected.

we do, but im not sure who has the video of them falling

im at school right now, but when i get home, ill get another rendering of it showing the bottom of it


thanks! yup
not sure but in the region of 21 degrees

4 wheel drive
1 cim per wheel
pnuematic casters for easy turning

there is no pivot, but we can score on all three easily

the side without

not much besides the supports and the driver's ability to stop their robot

less than 5 seconds probably about 3ish

released by a pnuematic latch and then gravity and some help from surgical tubing

thanks

Re: pic: 141 rendering with ramps down

Hopefully this will end up being a link to the YouTube Video of Team 141 Deploying their ramps. This was the second time we deployed, the programers had not entered the code to deploy so two students, one for each wing had to trip the pneumatic solenoids manually twice by hand. The operator control that is now programed actually deploys the wings a little bit faster. Each side can be individually deployed or they can be deployed at the same time. You are required to hold down one button and then press another to deploy, hopefully no accidental deployments! There are no supports underneath the panels. Honey combed fiberglass panels with alluminum J Channels around the outside. Extremely strong and lightweight. It is designed for a 13 inch elevation to allow for slight bending of the panels.

Re: pic: 141 rendering with ramps down

impressive. thats a nice, simple design.

I would suggest making a stop bar of some sort to keep pesky drivers from mauling your arm.

Re: pic: 141 rendering with ramps down

no offense taken...just figured three robots cant stop four ramps and also makes it convenient for alliance partners

I love the lighting on that... a little late, but good job!
