Team 997 Lifter

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.

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

We did add ramps during day 2 of the PNW regional. They worked quite well and we will be making them even better for the Davis regional and championship event!

Just dump the air, no?

Clarification: How do you deploy your platforms from the vertical position they begin in to the horizontal position they are in when actually lifting 'bots? is it just a "let it fall and hope it doesnt break" sort of thing, or is there some other system I'm missing in the pic?

997, your robot rocked. I remember seeing you guys at the scrimmage a couple weeks before the regional and our entire team agreed that you'd be going into the finals, if not winning. *and you won*

We'll be seeing you at the Davis Sacramento Regional. Hopefully we'll have match or two with you this time. Good luck!

one the support pieces for the feet stick out completely to the other platform where we have a pneumatic cylinder that shoots through a whole in the rod, and they are pulled apart by a budgie cord, when we retract the pneumatics, the bungee pulls them apart.
and yeah they just fall, but we looked at all of our parts and they don't hit to hard, they are just like big flaps so the air resistance helps out, also nothing is welded together so we don't have to worry about any of it cracking

this B...E...A...utiful just won it's second regional :-)
and for being the first year our team has ever won a regional we are really, really happy.

It was great being with you guys at Davis, the only question I had after seeing it was how does it continue going up after the power is off?

Once the air flow to the cylinder is opened, after power is cut, the cylinder will continue to be filled until the system is out of stored air.

This will happen as long as the solenoid is triggered before power is cut off.

It's probably* because the valves do not close when power is removed. As a result, the air in the tanks keeps flowing into the pistons, even when power is cut.

*Speculation, but it fits the scenario.
