The two bots who had ramps, when they did deploy, got no bonus points scored.
I remember in 2007, we gave away "Wings" (like you get on airlines, when you are 5) When teams climbed on our dual ramps. It became an ad campaign to get people to the practice field to get comfprtable with them. They were easy to climb when you've done it an have confidence. Of course that year the ramp was in the endzone right in front of them, but cant we do it that way this year? Do the ramp need to be in contact with the tower? I forget!

Re: Suspending

There is a huge difference between 07 and this years game. Starting with the difference between a 84 inch circle and a 72 inch square.

You only had to get a robot 12" off the of ground compared to 20".

Plus this year after you get two robots on the ramp you have to somehow elevate your own. All for couple points extra.

Re: Suspending

The Granite State Regional saw plenty of successful elevations, but not a single suspension... I'll be surprised if they happen much this season!

Re: Suspending

I bet someone will hang off of 2062's robot sometime, maybe just in practice, but they can support robots.

Re: Suspending

Kettering had two on one tower. They each used a vertical pole. The enginerds bot could pull this off but they would have to have the right partners and start very early in match. The way the seeding points are i don't see any reason not to try.

Re: Suspending

Ouch. It looks like some people misunderstood the definition of SUSPENSION. Ramps are only useful in getting robots onto the PLATFORM...

Being on top of a robot that is not itself ELEVATED or SUSPENDED earns you exactly nothing.

Yep - I stand corrected. It's funny how the rules can "shift around" in your mind when you aren't reading them on a regular basis. My mistake - and it invalidates my argument. I think I'll back and see if the edit feature is still available.

Mea Culpa.

And the only reason we didn't have a single/double lift at Kettering was because we never had the right partners. Team 1322 was close to hanging off of us, but there ended up being timing issues, and they pulled us down at the last moment. But we proved that we can hang teams, and I think at Ann Arbor we will see the first double suspend.

Re: Suspending

To add to what Zach said:

In the match with 1322, one of the two hooks on our Team's attachment mechanism was not secured to the field tower. Team 1322 successfully attached their robot to our supports, but since we were not completely attached to the tower, it caused our robot to move into a lower vertical position where we were no longer considered elevated. We are able to successfully elevate our (single) robot with the support of one hook, as proven in two matches at the Kettering University District.

After the aforementioned match, we discovered the root problem of the difficulty of attaching both hooks, and made some physical modifications to the design. These changes yielded positive results, which allowed our robot to successfully elevate itself in the successive matches.

The last determining factor that attributed to our inability to allow another robot to suspend from our mechanism, is that the alliance selection assignments did not provide our Team with an alliance partner whose robot had the ability to suspend itself off of the tower. Since our robot is designed such that any robot with the ability to elevate from the tower also has the ability to be supported by our robot, no one was able to attempt to suspend themselves from us.

I would also like to thank Team 1322 for your immense efforts to attempt to suspend your robot from ours. Had our Team's second hook successfully attached to the tower, we certainly would have seen the first elevate/suspension! Thanks for all of the great teamwork!

-Clinton-

Re: Suspending

Multiple elevations weren't uncommon at the FLR, even though we had no suspensions.

It's not as though we didn't have plenty of multiple elevations at Kettering, either. Teams like 27, RUSH; and 33, the Bees, could easily elevate while another team that used the horizontal bars elevated, but ours was the only match to see something even close to an Elevate/Suspend; however, there was another match where Lapeer East was positioning themselves to suspend from us when we had gotten both hooks onto the tower, they just never even really got started before the countdown finished.

Eastridge Robotics 3157 is proud to be an FLR suspender, along with Lockport 1507, Victor 1559, and Naples 1551. There were some occaisonal suspensions from Pittsford 3181, 1126 Sparx, and even 191 Wilson-Magnet.

If I may so humbly say, we had the best lift of the FLR, hands-down... And we weren't even close to seeing any viable situation where suspension was possible.

I was hoping we could have a match with you. I really wanted to be the first to get the 3 points! Come late friday night we had our hanger all worked out and beautiful. We could lift in 10 seconds or less from the floor in all of our three sat matches with ease.

Yeah, we grabbed onto the bar every match, the Friday matches we didn't set up in time or get a full lift. We worked very hard to get the lifter working by our last match Friday. But due to a strategy decision we did not lift our last match on Friday. But come Saturday we did the remaining 3 matches no problem at all. I wished we came up with that solution on Thursday.

If we only count our lifts on Saturday, I would think that we were the best lifter behind 1551. (or no?)
