Great job there Team # 3310. A great robot.
But there are multiple teams with a 0.25 second grab (some that haven't done a release video, I'm certain) so if two end up on the same alliance, bad things will happen.
It's also totally possible to have a 0.25 second 4-can auton with large enough pistons.

.25 seconds is well near where it's hard to go that fast without intelligent control. Hence the motor on 3310.

The faster you go the more energy you need to dissipate to stop.

Why not have the container dissipate the energy? The sort of hook 3310 and 118 have might bounce out, but a latching hook wouldn't have this issue. Also, if you hit the handle hard enough, you'd move the container out of the way to prevent anybody from grabbing it without having to worry about timing to drive the robot back.

I just can't wait to watch some tug of war!

Using tractable hooks, like a harpoon. Once we have it, it's not coming out.

Re: 3310 Robot Reveal

What happens if a 4RC grabber can latch into the top of the RC equally as fast but then 3310 takes off? Wouldn't 3310 likely pull one end of the 4RC grabber across the step?

Would be an interesting tug of war to say the least.

Indeed... ever hear the story of how hunters capture monkeys where they get their hand stuck in a jar and will not let go?

You may wish consider letting go as a failsafe, and have a backup plan.

Re: 3310 Robot Reveal

I could be wrong but it seems like yall are sitting in the landfill to grab the cans? I didn't think you could just flop an arm down onto a can with your robot sitting stationary in auto and still be within the height limit.

No, we start fully out of the landfill zone. And geometry is your friend

So do the harpoon hooks retract to let go... or do you let go from the other end and lose the arms... probably be a good idea to share how to let go... as that would be a benefit to everyone... especially to the person who still wants to hang on.

So do you move forward into the landfill, or does your arm reach from the auto zone?
