Re: Team 1501 is coming to play
so is the curved surface on the back in case of a tip?

Re: Team 1501 is coming to play
I think it's because it looks cool.
The secondary reason might be because curves make monocoque extremely strong, but that's still secondary :-) Nathan |

Re: Team 1501 is coming to play
First lets say that we don't have a typical front to our robot this year. We have a Sail Side and a Fork Side. It took many confusing conversations before we came to this terminology, since we drive forward on either side of the robot being the forward direction with a flip of a lever switch.
The curved surface is the Sail Side and is curved for its strength and to allow the initial starting dimensions. The pivoting action provides the telescoping of the carriage rails to "Load" our launch device and simultainously pick up the ball in the same motion. We are very proud of this design and very confident that the safety judges will agree that our tension device is safe off the field, which was a major concern through the design phase. If you like the robot so far, just wait until you see the "remove the ball from the overpass thingy" we have yet to reveal. Along with the vision routines this device will be very simple and very effective. |

Re: Team 1501 is coming to play
Cool bot...what happens if there are two trackballs of same color near each other an equal distance from your camera???

Re: Team 1501 is coming to play
As far as we know from the rules, that won't happen during the initial field setup for the autonomous mode as there is only to be one ball of each color on each side of the overpass at the start of autonomous mode.

Re: Team 1501 is coming to play
very nice robot!
are the large pistons mounted on a casing around the forkside axle shaft? and whats the release and reset mechanism on the forks? and are the ropes and gas piston? there to support the welds on the forks? |

Re: Team 1501 is coming to play
very nice way to deploy the forks.
in the other post i was referring to how do you release the forks for launch? and then bring them back down to reset? |

When the sail is in fork truck mode, the tubing is loose, no tension. we lock the latch. stretch the sail like stretching a rubber band..then we release the latch like pulling a pin. It's a safe setup when in the pits, unless we stretch the sail... After the sled fires, we return to fork truck mode, sail returns, and the forks fall at a rate of 32.1740 ft/s² or 9.80665 m/s². |

When the sail moves forward it stretches the tubing. When we are ready to fire the operator triggers the release. The first thing that happens is the flag is moved out of the way (it's on a pivot) than the trigger is released. When the sail is brought back, the trolley (where ball rests) moves back down the tracks using gravity. When it reaches the bottom the trigger moves out of the way (it's on a pivot) and will drop back when the trolley is past. On the trolley is a piece of angled steel that the trigger catches on. |

I’m really proud of 1501 this year with a fantastic robot. I wished I would have been there more this year, but school and work have been keeping me busy. I'm trying my hardest to get to BMR this year to cheer on the team and all the other teams that are going. So good luck to all of the teams this year!!!
Goober!!! ![]() |

Re: Team 1501 is coming to play
you mean the forks fall at a rate accelerating at 9.8 m/s² ? assuming you have perfect sliders

Re: Team 1501 is coming to play
We will once again be having the "Guess the Rivet Count" game at BMR.
The person who guesses closest the total number of rivets, in our robot, WITHOUT going over will win something nice. What it is I have no idea The number of rivets is NOT 1501. |
