Re: Team 71's 2002 robot

what the heck is this "tether" the MC is talking about? it looks like some sort of ribbon? Does it extend the robot to the "end zone?" what is the significance in that?

sorry, I was only 25 then and in school at the time.

One of the methods to gain points in 2002 was having part of your robot in your "endzone" at the end of the match (segment closest to your alliance station). Any part of the robot counted, so many teams devised tethers they dropped and left there and/or "runners" that would drive back on a tether towards the end of the match in order to get these points while still being in position to control the goals.

Re: Team 71's 2002 robot

Here's a description of the 2002 game: http://www.team237.com/2002game.html
Here's a good photo of their robot that year: http://www.chiefdelphi.com/media/photos/12168
Their feet were made from filecards. They didn't actually lift the cards, instead they shuffled them back and fourth to move the bot forward. Try it yourself, put a filecard face down on the carpet and try to push it back and fourth. Now imagine a hundred pounds of weight on the card and you can see why nobody could push 71 backwards.
Once 71 had the goals that year could be pushed sideways, but not backwards. You can see it happen in one of the videos I have from 2002, but I don't remeber which one. http://www.students.ccsu.edu/~rodriguezjel/2002/

Re: Team 71's 2002 robot

I heard from someone that played against that robot that it tracked the middle goal, but if the goal moved then they would only be able to grapple one goal. the middle one. They also said that they developed an auton that would run out to the middle of the field and ram the middle goal in order to throw them off.

There was no autonomous back then, so no tracking. It was all driver speed and robot quickness.
71 could be beat out to the middle goal, like 180 did, but it was rare.
Here's the national semi, team 71 v team 60. 60 just beats 71 to the goals, but 71 wins out. It was possibly the most anticipated match of the year. http://www.youtube.com/watch?v=lAmAn...eature=related
71 could grab and push as mentioned, 60 could grab 2 goals, lift them off the carpet and spin them around the robot so no one could grab them. Quite impressive when you consider those goals weighed about 180lbs each.

Not totally true. There was no autonomous period--that came in 2003--but I have heard that one particular team did run mostly without driver control. There were targets on the goals that sensors could see.

Remember, you don't have to have an autonomous period to be autonomous. You can run the entire match autonomously.

Tis true. The mast in the center of the goals had retroreflective tape on them that played horrible games with pretty much any photographer using flash...
But not many teams used them for their intended tracking purposes.

Filecards are used to clean files, and have many small metal teeth/fingers. Try sticking one into a carpet sometime and pulling. Good luck moving it.

We (190) used them as well, but as anchors. The robot would drive in between two goals, latch on with cables/hooks and drive past into our zone. The anchors would push down into the carpet, raise the drive wheels, and then pull the goals back. It was literally impossible to move the robot. I had always hoped to go head-to-head with 71 to see if they could move us without ripping a hole in the carpet underneath one/both of our robots, but we never met up on the field.

The only way to move the goals 190 hung onto was to literally rip the robot in half. Didn't that happen at Battlecry that year?

We (311/308/180) faced 190 in the first round of the eliminations that year.

Re: Team 71's 2002 robot

At the Midwest regional that year my team, 93, beat them to the center goal by about 1 sec and rammed it into them lifting the top of their robot into the middle of the two platforms lifting all their wheels of the ground causing them to not move the rest of the match. We ended up winning the match, I've never heard a crowd cheer louder in all my years since, when that happened.

You guys hit us so hard that the goal was embedded in the front plate of our robot by a good quarter inch. It took three of us to pry it off I believe.

In the second match of the Einstein finals, SPAM beat us to the center goal and our arms missed the outer goals. We were left without any goals and that robot was not designed to do anything more than move forward fast and then move forward slow. I tried to do what I could to turn the robot and the intent was to push the goals and all robots into our endzone, but that never happened as an axle got bent as our robot got smashed against the side rail. We sat the third match as 173 and 66 finished what we had started.

Ah the good old days
