Robot Lifting

[bobosalad]

what about using the scissor lift to attach a wench hook and have the cable go back the the robot with a wench at the end, the scissor lift would not have to be strong enough to lift the robot

Earlier people were talking about the fisher price gearboxes. How would you attach them to the winch?

I'd use an octagon with a keyway or hex in the middle, cut to the size needed to fit into the FP's output gear. Then I'd use whatever attachment was needed to get to the drum.

Alternatively, I'd use a direct octagon-drum adapter to get it right on the FP gearbox.

Question about lifting and hanging:

Rule <G05> States:Scores will be assessed after all objects in motion, when the ARENA timer displays zero seconds, come to rest, or 10 seconds after the timer displays zero seconds, whichever comes first.

Rule <G03> States:The TELEOPERATED PERIOD ends when the arena timer displays zero seconds. This also indicates the end of the MATCH.

And Rule <G42> States:ARENA Reset Delay - ROBOTS must release any portions of the TOWER, PLATFORM, or ALLIANCE ROBOT without power after a MATCH. Violation: YELLOW CARD.

So. When exactly does the robot lose power? Is it right after the MATCH, and so the robot would have to hang up to ten seconds without power? Or does the match end, then wait for all objects to come to rest or 10 seconds like Rule <G03> states, and then power is cut?

If you have any info that would be very helpful, this could be quite a problem for us!

Thank you much!

Power is cut (or rather, the robot is disabled) at the end of the match (0 seconds left on the timer). Moving things have 10 seconds to come to rest after power is cut.

so if you fall below the platform before 10 secs after the match it doesn't count. It hapened to a team a few times at cass tech.

We -- who I am proud to say have the highest number of 'hanging points' after two weeks of regionals -- put a very simple mechanical catch so that when we were lifted all the way, we wouldn't come back down. The screw drive doesn't backdrive all that fast, but it *does* backdrive, so we had to be sure...
