Re: Robot ideas
Since my fantasy forklift would use pneumatics, it wouldn't be hard to include a small arm that could place a ringer on the low spider posts. A little offense, a lot of defense, capable of picking up two bots at once. Sweet...

I like your idea with the short and defensive robot but what if you are put onto an alliance in qualifying that has two other teams that barely do anything (i.e. wheels on box bots) then you lose a match because of that. I feel each robot should be self sufficient so that it can score well. They only count points for scoring offensively. Your idea will be a good plan for newer teams to design a simpler robots that might not have the ability to make an arm or program a light sensor. Good post. |

Re: Robot ideas
Want robot ideas? Look to 2005 and 1997, at least for ring manipulation.

Re: Robot ideas
our team decided the most awsome(and hardest and least likely lifting mechanism) is akin to a inflatable raft. keep it rolled up till the last 15 seconds or so, or more. drive to home zone, unfurl it(note that it is NOT detachable, it remains attached to ones robot via pnuematics/air cables). alliance robots then drive ontop of the "raft" and it is inflated with much speed. if anyone can accomplish this, i will be impressed. have fun.
btw, first post, gogo penguins! -coop |

Re: Robot ideas
I'm from a rookie team and we discussed the idea of focusing on a robot that could lift and play defense, like the one mentioned before.. One post stated that there are a possible 596 possible points an alliance can get, but how many of the possible points is a team truly likely to get, for instance, based off of previous competitions. I mean, If my team can get 60 points by lifting the two alliance partners off the ground would that make us a valuable alliance partner in the finals?

Re: Robot ideas
I am scared. NOT!! Now I have ideas to use, once we decide strategy and requirements.
You guys should slow down. You can't design a robot in 12 hours or so. Well, I suppose you can, but the one that someone takes 3 weeks to design because they were analyzing the game for 1.5 weeks will slaughter it. Take some time to analyse the game first, then design using these ideas. I predict that some of you, with the level of analysis shown here, will be very surprised at a competition. |

Re: Robot ideas
Yes, you would be a valuable alliance partner. But keep in mind that your alliance partners may have problems, if they fall over or have a drive malfunction they won't be able to make it to the end zone and you won't be able to lift them, and won't get your 60 points. If you can score some rings in addition to lifting, you'll be even more valuable.

Lifting mechanisms are going to require some very careful and good thinking if you want to ensure you can lift ANY robot. |

Edit: Actually, I guess a flower-petal design with some light metal would work decently. If you have a 1ft-tall robot with a 3ft-tall deployable ramp, then the angles required aren't as bad (18 degrees). If you go for a very tall robot when not folded, then you just have a 11 degree ramp for the mounter to traverse, which is definetely doable. It'd still make me very nervous to have another robot on top, but it'd be workable. If the ramp was side-mounted, then it should be wide enough that navigating it wouldn't be impossible, though you'd still have a tipping risk if your alliance partner came on too fast. Edit2: Like the attached renders I just made. Which I guess is very much like the wildstang shots shown before. Last edited by Bongle : 07-01-2007 at 10:57. |

Re: Robot ideas
We were tossing around ramp ideas yesterday....the more you think about it, the more solutions there are. Building some of them would be quite challenging, but you really do have a lot of room to work with as far as storing a ramp, if you are careful with the design of both the ramp, and your tube handling arm.

Re: Robot ideas
Just thinking more about ramps, you could help with a lot of the tipping and space issues by making a bent ramp so that it greatly increased the amount of flat space to drive onto.
The attached one would have a 2 foot long flat section, then a 3 foot ramp section that climbed at 18-degrees to a height of 12 inches. The total amount of flat space would be 3 feet wide (maximum length of robot) and 4 feet long (2 feet on the ramp + maximum width of robot). Mechanically all you'd need is a tiny latch on your manipulator arm (presumably on the left side of the shown robot) and maybe a tiny pusher to get the ramp to fall down. Problem with this is that you're now limited to a 100lb robot that needs these two huge towers on it, and has to be built to support other 120lb robots. I'm not an mechanical engineer, but it seems that this design of ramp could be built pretty lightly if you were creative with materials. If you put some vertical posts on the underside of the ramp that had really grippy feet, you might remove the robot-shaking issue when mounting as well. Last edited by Bongle : 07-01-2007 at 12:18. |
