Fuel stuck in front of lift.

How many of you have taken time to figure out what you are going to do if there is a row of fuel in front of the lift you are trying to deliver you gear to?
Have you designed your bot to "reach out" to the bumper perimeter or some other method to defeat these pesky fuel in your way?

Re: Fuel stuck in front of lift.

I assume for a decent amount of teams, that mechanism is called an "intake".

Re: Fuel stuck in front of lift.

I expect a lot of teams will just drive into the balls and mash them into the wall. They're soft, deform easily, and seem to pop back into shape.

Engage Ramming speed!

In all seriousness.... that's usually the solution to a lot of issues in FIRST . My only worry there is that you might end up on top of some of the balls. For a lot of robots with low bumpers that will spend the end of movement.

If it gets particularly bad I'm sure a run or two with the intake will clean it up.

Re: Fuel stuck in front of lift.

Spring is 10.5 inches, ball is 5, bumpers are 3.25, still gives you 1.75 inches of space... Seems more than enough if you thought about your robots design....

The gear is what, 2 inches thick? And the spring may deform / drop the gear if only partially placed on the peg. Can still probably "just" crush the ball though.

Shove it on. Firmly. With authority. And don't miss.

Dropping the gear there creates a (much) more serious problem.

Re: Fuel stuck in front of lift.

Fuel in front of the lift and the droopy springs caused us to change from a passive hanger to a system with a door and a system to push the gear out so that it is ~8-10" beyond the frame perimeter.

Even so, we're working on some spin moves to see if that clears the fuel both at the lift and the intake. Our robot is about 4" wider than it is long, and will have a gap in the bumpers front and back.

Re: Fuel stuck in front of lift.

Balls in front of the lift (and the loading stations) were part of our design from the beginning. We plan to do like Richard Wallace suggests.

Just don't shoot the gear onto the peg. Shooting gears is against the rules.
