Re: Drive Systems
What is the bumper height restriction this year. I see nothing in the specs.

[R01] see the whole rule as trimmed for content......... The Frame Perimeter of a Robot is defined by the outer-most set of exterior verticies on the Robot that are within the Bumper Zone, which is between 2 and 10 in. from the floor. Minor protrusions no greater than ¼ in. such as bolt heads, fastener ends, and rivets are not considered part of the Frame Perimeter. To determine the Frame Perimeter, wrap a piece of string around the Robot at the level described in [R02]. The string describes this polygon. Note: to permit a simplified definition of the Frame Perimeter and encourage a tight, robust connection between the Bumpers and the Frame Perimeter, minor protrusions such as bolt heads, fastener ends, rivets, etc are excluded from the determination of the Frame Perimeter. Why this isn't in the bumper section i'll never know. EDIT: Howdy neighbor! :-) |

Re: Drive Systems
May our 14" mechanism expand in the bumper zone outside the robot?

Re: Drive Systems
I would assume so. My POV regarding this is that the bumper zone is only a bumper zone when there are bumpers present. That sounds a bit confusing, but what I'm saying is, you have your bumpers set with the openings, then you have an arm(or whatever) at the same level as your bumpers, then yes, its seems like you can expand there(if that's what you're asking)

Re: Drive Systems
I don't think so -- any more than driving across a tilted ramp would violate the bumper height rule. The bumper height is clearly relative to the robot, and not to the absolute plane of the court floor, else any ramp action is inherently illegal.

Re: Drive Systems
Team 610 in 2010 had ~10" pneumatic wheeled 6WD; the middle one rose and lowered so that they had an easier time with the bump. I'll try to find a video, but most of them are low res taken from far away. Anyone have a picture of it? Still my favorite robot of all time.

Re: Drive Systems
This was posted in a different forum. It's a really cool way to drive the robot, but i'm not completely sure how effective it would be for this years game.
