Re: pic: Ramp Video
Joe, it seems to me that as the middle wheel goes up, the outer wheels go down. Wouldn't this cause the bumper height to change? Bumpers must remain in the BUMPER ZONE, 10-16" off a level surface.

Re: pic: Ramp Video
Key phrase--"level surface". If the robot is set up on a level surface, are the bumbers in the bumper zone?

Re: pic: Ramp Video
You also have to watch out for your max height.
Don't make the robot 5 feet above the frame, make it 5 feet above the wheel at the lowest point. How they would test this in the box.. I don't know. But still, ask the Q&A if you guys go with it. Awesome drive. |

The measurement is taken when the robot is on flat floor. We meet all requirements that we have found in the rules. The bumpers are between 10 an 16 inches above the floor when on flat ground. |

Looks like your center wheels are 2 individual omni wheels per side, each one slaved to either the fore or aft mecanum wheel. So basically the center wheels are commanded to have the same velocity profile as the front/back wheels. Is this accurate?
btw, awesome design and thanks for sharing your ideas. We're a second year team so still need lots of help! |

Re: pic: Ramp Video
There's a ball differential so if the front and back wheels are spinning in opposite directions, the omnis don't turn.

Re: pic: Ramp Video
This may sound a tad bit pompous but that seems like lawyering to me. The way we look at it is: What's the purpose of the rule? What is it trying to stop us from doing?
Last year, there was a robot that had fans on the bottom of it at the Portland regional. The idea was to suck it down to the floor in order to gain more traction. The judges didn't let it slide and the team ended up with a box on wheels. I'm not trying to be a rules Nazi, I just think the judges won't let it pass and you'll be in some serious trouble... |

The Q&A is the only way to figure out answers to designs like this. |

The rear virtical strut will pivot at the frame.
