Is it possible to throw the ball over the overpass? And if so are there any velocity or safety restraints?

Re: Throwning the ball over the over Pass
I have not seen anything in the game rules saying that you cant catapuls balls. I have also not seen anything about restraints either. It is also possible that I just completely missed them both. I dont think they are too worried about a velocity though. I dont think that ball will be able to go yery fast, I think if you launch it it will just kind of float like a beach ball, however I have not got to see one of the balls up close yet. None of these are definate facts, so take them for what their worth.

Re: Throwning the ball over the over Pass
ok thanks i was just wondering if it was at all possible. because to have a 10 lb ball flying through the air there might be some restrictions

Re: Throwning the ball over the over Pass
alright our team has been discussing this option a lot...but I realized that the catapult idea wouldnt work if they wanted to say...hurdle...the ball
first off, in the definition of hurdling, it states "be moving toward the OVERPASS and/or elevating the TRACKBALL so that the top of the TRACKBALL is higher than the LANE DIVIDER." that means ure catapult will have to start at 6 feet (ht. of lane divider) in order for your robot to succesfully hurdle correct me if Im wrong... |

well the trackball itself is 40 inchs high on the ground, giving the facthat it is the "TOP" of the trackball must be over 6ft. the ball is already 3' 8" without any support so really the catapult only needs to hold the ball up another 2' 4" which realy isn't a big deal! |

The rules could care less about how a Trackball gets above an overpass. You should be able to use a catapult, even if you are setting still and the top of the Trackball is not six feet off the ground. You will not be getting the protection of G42 if you are not moving towards the overpass tough. |

Re: Throwning the ball over the over Pass
yea your right i dont see anywhere where it clearly states that you have to throw the ball in that motion which leaves alot of options open

Re: Throwning the ball over the over Pass
So that means that if............
---------------------------- / Robot was | \ / O <- here | \ |_____________ | ___________ | | Alliance | Ball could | \ Home | be thrown / \ Stretch | here -> O / ---------------------------- ...........and still count as a hurdle. As long as it passed over the alliance's overpass, Our team believes it would, and the only down fall was that the robot wouldn't be considered "hurdling" and under the protection. *If I'm wrong please let me know. I don't see anything wrong with it though. |

Re: Throwning the ball over the over Pass
Today team paragon tried a mock game with students and a ball. We tried to toss the ball over the overpass but it didn't work out to good we only got it once. Also when we threw it over after the field was built someone got knock down on to the floor.

Re: Throwning the ball over the over Pass
No you cant throw the ball over backwards, look at the definition of crossing

Re: Throwning the ball over the over Pass
My last post had a text picture that did show up so below should be a corrected pic.
Apparently spaces don't show up????? ????????..................----------------------------.................................................. ................/ Robot was.....|...................\..................... ........................... .............../ O <- here.......|....................\................. .............................. ..............|_____________ | ____________|..................................... .......... ..............|......Alliance..... |....Ball could....|........................................ ...... ...............\......Home........|...be thrown..../............................................... ................\....Stretch......|.....here -> O /................................................ ..................----------------------------.................................................. |

Re: Throwning the ball over the over Pass
to ccsingle07
yes, I think. It is traveling counter-clockwise, so I see no problem with this. |

Re: Throwning the ball over the over Pass
anybody know of a fairly reliable formula for figuring out air resistance on the ball?
I've looked up the formulas online, but all I'm able to find is "high velocity" formulas and I'm not sure what exactly a "high velocity" would be. |

Re: Throwning the ball over the over Pass
Unless I have messed up my kinematics, an initial velocity of 6.25m/s should launch an object 2m into the air, which should be plenty for hurdling. Given that this is about 23km/hr, I suspect you could adequately account for air resistance by just aiming to put the ball 30cm or so over the crossbar.
Now how you accellerate the ball to 6.25m/s... that's another issue. Jason |
