The proceeding was the clue from last year. The max velocity of the arm to grab the bar wasn't so encrypted. Last year people noticed the quote was from a Led Zeppelin song. So maybe the Beatles idea isn't so far off.

Thanks!
The clue was a Led Zeppelin song lyric from "Stairway to Heaven". We all then assumed there was a staircase or multiple steps to climb. Many of us (including me) believed there might be a "Stile" as a centerline divider access (or choke point) device, to replace the dual ramp or teeter totter in past events.

We were PARTLY right. It wasn't a "stile" ladder after all.

Instead, the center platform had three 2" microsteps at each end (a misdirection IMHO, as any robot using them would then have to navigate around the static goal on a VERY narrow shelf to get to the bar) . It also had a 6" (or 12") step if you approached the platform from near a midpoint side.

If your bar device required you to be directly under the bar, you were forced to "climb the staircase" by stepping up 6" twice.

BTW... The 10ft/sec maximum also in essence threw out ballistic acquisition of the bar from the floor. Do the math to determine how close you'd have to be for a 10ft/sec projectile shot upward to stall out vertically and you'll see what I mean... You had to be so close, manual placement was (IMHO) easier, and more reliable.

Does this help?

Now... Given THAT, how do we interpret THIS year's clue???
