Let the truth be told.

Re: Contact with the Rack
 

The rack rotates around it's own axis but it is DIFFICULT to do so it's not aa BIG concern but it could still happen....and it shakes alot...

Re: Contact with the Rack
 

The estimated weight of the rack at kickoff was over 400 lbs!! It takes 3 full size adults to move it easily, 2 adults can move it, but it is not lite. It is constucted of schedule 40 aluminum pipe, and angle. I doubt any single robot would move it.

The "spiders" are hung by chains, and attached at the bottoms by rubber bungee cords. They move quite a bit. If you try to push on them the bottom ones move about 2 feet, the top ones about 1 foot

At Pittsburgh last year one robot was able to move the corner goal and part of the driver's station wall back about 3 inches. They were attached to the carpet with three, 1 ft x 3 in pieces of velcro. It was a full-speed hit during autonomous, so the force was probably about the same we'd see this year if a bot ran head-on into the Rack from their starting position.

In Pittsburgh, as I recall, the Head Ref ruled it unintentional and gave the team a warning that if it happened again (which it didn't) they'd be DQ'ed for damaging the field.

My point is that during aggressive play we are likely to see the Rack move a bit from "incidental robot contact". 130 lbs at 10+ fps is a lot of force.

So the spiders are able to move, but the question is... can the spiders be turned or rotated, rather than just sway back and forth a foot or two. :confused: :confused:

Re: Contact with the Rack
 

the spiders can sway left and right since they are hung by chains and held by bungie cords, up to a foot from the looks of it. but to fully "rotate" them you would have to move the entire rack left or right to move more than a foot either left or right, from the origional spot.
