Team 997 Lifter
 



This is our lifter.
It starts out in a folded up position and plays defense throughout the match.
near the end of the round it returns to the home zone and deploys two, (approximately) 4 foot tall "wing" which are raised using 4, 11 inch stroke/1.5 inch bore pneumatic pistons. The platforms are made out of a honeycombed cardboard center with either plexy glass or carbon fiber material on the top and bottom. They are strong and weigh between 4-5 pounds each. It can lift both platforms individually without tipping the robot. It sits on a track system with 4 cim motor and the Andy Mark 2-speed drive trains, although we did remove the higher speed to take off weight, and in high speed it was to fast to control.

It was designed to do one thing, and one thing well. :cool:

how do you get your partners over 12" high when it looks like you start at 1" high and stroke out 11" ?

Same to you 1983,
you guys had an awesome pit (i think you even won an award for its colors?)
and that bot really came together on the first day, I really liked the idea for grabbing tubes then turning them sideways to score. The way your crate held all your tools and had places to hang everything was really a space saver, but did you guys have to pay overages on shipping costs?
BTW your mascot really rocked ;)

Out pistons start out fully contracted when the platform is on the floor, then we have our 1 inch Angle Stock and the .5 inches from the platform material. this gives us a little leeway, just for good measure.

I was glad to be in Portland to watch your robot in action. The final match really amazing! Best of luck at Nationals.

im not sure about overages but if there are any they are worth it. And yes we did win the imagery award.

Looks great. :)
We considered this when we were in the prototyping stage. The biggest draw back we thought would be if someone hit one of the wing end cylinders and bent it.

Re: Team 997 Lifter
 
actually, we have support and protection when raising and lowering the platforms, they are attached to the feet at the bottom...

Re: Team 997 Lifter
 
Did you guys say you used carbon fiber? what are the rules on that? someone told me that it was illegal i might be mistaken but ye?

pakratt1991 07-03-2007 00:23

Re: Team 997 Lifter
 
Yeah one of our platforms is carbon fiber coated, and one is fiberglass coated(I said plexy glass the first time, my bad)
I don't think that it is illegal to use but I have not looked it up... yet

Re: Team 997 Lifter
 
Carbon Fiber is ok
Way to go 997, glad to see an Outback MFG team make it!

We'll be seeing you guys (and gals) in Davis, this time w/ a robot that can do more then drive around w/ tracks. :)

How do you guys lower your platforms?

696 used pneumatic lifters too. We (1070) have a lift similar to yours but we powered it with two CIM motors.

Re: Team 997 Lifter
 
ok a bit of suggestion if u have the weight, add a small ramp so bots can get on it easier, alot of bots that i have noticed have under a inch of ground clearance
