The thing about kidnapping
The problem with kidnapping is the need for it in normal qualifying matches is minamal unless you are really being blown out. To make up for this we pickup as much as possible during the practice rounds to demonstrate our ability to do so. Otherwise it's not too helpful until finals when its just a pulling fest. We finished in 16th place at WMR and ended up not getting picked. Thats the way things go sometimes. As for Nats, were hopeful to do a little more kidnapping ( we did it about 4 times at WMR ). Thats the stats and story on our fork bot.

AAAAAAAAAAAAAAAAAAAAA!!!! (Sorry, trademark yell)
Howdy,
Long time listener, first time poster, first time FIRST engineer... I tried to find a picture for those interested. Then I realized I didn't have a good one of the lifters. They are bar stock with cables about 5 in from the pivot point. They are powered by 2 of the ...uh... large bore cylinders at 60 psi. We can lift ...uh... Tony. Maybe a list would work best. - 862 can't lift anyone TOTALLY off the ground - that's crazy talk - 862 has only tried to lift very stable robots, any only one side - 862 only lifts a few inches - just enough - We really REALLY don't want to hurt another robot, because robots tend to hold a grudge (as I am quickly learning) ![]() - We really wanted to do more than move goals - We never considered a baller getter chucker thingy since we didn't have alot of money. (Most teams spent more on speed controllers than we did on the robot) - Did I mention we really REALLY don't want to hurt any robots? Because we don't want to hurt them. - We wanted to learn about the pnumatics, and had nothing else to do with them. Seemed like a good idea at the time. ![]() - We tried to think "outside the box" and lifters happened to be right next to the "box". Anyway... all good things to learn for next year. Brian (Not2B) (Heebie Geebie) Graham P.S. - I saw the "no harm, no foul" message from the Chief about picking them up. Glad to hear that from you... we didn't want to upset anyone - just try to come up with something a little different, a little fun. Last edited by Not2B : 10-04-2002 at 22:32. |

We have a multi-function device on the front of our robot. It engages goals and allows us to pull or push them. We also can lift them up to lock the goal in place and transfer weight.
Why does a description of it belong in this thread? Because we can also get under other robots with it and push them around. We've done it to Kingman when they were carrying goals, though admittedly it was during a practice round. No harm done to Kingman either, we asked. It also reduces the need for a bumper. With that pointy thing out front nobody wants to hit us. |

Forklift Robot
I think that I wouldn't, unless you can do something else. Also, can't you only hold it up for 10 seconds? That is a major downfall. Also, you can't get under the goal and get disqualified. Probably not the best idea, but you might do well. Once again, just my thoughts.....

Lifting isnt considered pinning so we can hold on as long as we want. This isnt the only feature of our robot anyways, we have a hook to grab to goals with as well.

Team Update 6 had some questions culled from the Yahoo message board.
Q: Is it legal to DRAG an opposing alliance robot against its will into your home zone for an additional 10 points? A: Yes, be careful that the mechanism you are using to attach (or drag) a robot can be easily released. Also remember that the 1-minute setup and resetting period will apply, see GM6. Q: Will this violate the 'PINNING" rules? A: No. Pinning refers to holding a robot against the edge of the field or against the side of the goal. Lift away! ![]() Last edited by Wetzel : 11-04-2002 at 17:36. |

Fork Lift Robot
It appears I spoke too soon. My understanding was that you could not pick up robots, it would be considered pinning, but I was proven wrong. My mistake! Sorry, it is smart since you can disable the other robot without being DQ'd.

Can you lift a bot that is lifting goals?
Team 469 incorporates lifting ability when attached to goals, since you feel that you can dominate goal bots in that respect, do you also have th capability to lift about 130 lbs plus the added weight of 2 goals say about 300lbs? have you ever tried?
as for my views about the legality of forlifting bots, i say its a great idea, as our team discussed it but felt the clause in the ruling to be too risky for our tastes. -TheChosun |

i might tinyfarnsworth
It all matters what else can you do. If you can only "pick" up a robot, then no. But if you can handle balls and/or grab goals maybe.
I mean, it would be nice to have a bot tat could disable the powerful robot trying to torque us so i might even say yes actually if all you could do is that and hav enough power to win some tug-of-war matches |

I think bot lifting is a very good idea and is perfectly fine thing to do. I'm sure the inspectors make sure the device is safe for other robots, being as strict as they were.
Lifting was one if the wacky and crazy ideas that I was pondering... along withe electromagnet goal grabbers... |

Whee...
Something I just realized is that our robot is somewhat invulnerable to being lifted. Unless you bodily pick up all 4 wheels of the ground (unlikely, unless you have forklifts that extend 30 some inches), you'll never be able to put us in a position where no 2 wheels (all 4 are powered) are off the ground - our wheels are on the outside of our chassis.
Check it out: http://groups.yahoo.com/group/gsgisr...s/files/IT.jpg After reading the menagerie of posts about the subject, I can see how some teams might get concerned about the safety of their robot when being lifted. I say, try all you want. We may get loose somehow with our two remaining wheels, and we have an 80 pound aluminum chassis with no moving parts on the bottom. Scratches are always cool-looking However, I can see how other teams might be worried. A lot of teams I've seen have internal wheel assemblies, so picking one up might make them motionless (and subsequently draggable/sitting ducks). I like the robot design. It shows thinking outside the box, just like Beatty. If we ever have a practice match with or against you, please try to pick us up. I want to see if I can outmaneuver and/or get away while being lifted ![]() |

4 wheel drive
We thought this through in our design phase, we have tiny barbs at the end of our forks _____A (crude picture) about 2 cm high that can be removed that holds on to a cross beam on the opponents bot. And even with 4 wheel drive what happens is a reduction in traction on your part and an increace in traction on our part due to the shift in weight of your robot. although it may not be as easy, we still think we could pull you around. although we always like to see casters on bots
