Team 71's 2002 robot
Hey,
So I wasn't around in 2002, but I have heard many stories about team 71's robot that year. I have seen video from Einstein, and I am very curious as to how the "walking" mechanism worked. If someone from 71, or anyone who remembers, could explain it or has pics, that would great. Thanks, Seth |

I just want to make sure I'm getting this right lol:
It was impossible for the other alliance to win if 71 got their thing out quick enough, am I right? |

I wasn't around in 2002 (FLL maybe) but from this video on the HOT team site link
it looks like it was really hard to overcome the Beast's ability to grab onto all three of the goals in the first seconds of the match. The HOTBOT tried to ram their arm, and that match the Beast only grabbed two goals. BUT, they also grabbed onto our robot and dragged it with them for the rest of the match. I'm curious as to why 71 didn't grab any of the goals in the second Einstein final match (from the vids on TBA). |

It was a combination of SPAM's (team 180) incredible speed and a well thrown soccer ball at the beginning of the match. The ball ended up under 71's machine as it fell into it's operating mode as SPAM made contact. Our alliance (311 308 180) went on to beat them that match to make it a 1-1 tie in the Finals. I have to mention that one of our alliance partners, team 308 from Walled Lake Michigan. Their robot was able to pick up 2 180lb goals and then move forward into the scoring zones. Looking back I appreciate the ability to do that given the limited motor selections, transmissions and technology available at the time. You have to realize this was pre-AndyMark after all! Team 311 only lasted 2 more years after that. The Championship Finals at Epcot was one of our highest achievements. |
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. |

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/ |

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.

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. |

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. |
