That's pretty sick. Nice job. "ludicrous speed" lmao

AdamHeard · #3 11-09-2007, 22:55

I like! I imagine Vex become very very competitive this season.

Thats awsome Chuck, good job 1712.

Jeff K. · #5 11-09-2007, 23:14

Nice!

It's a shame FIRST is going away from vex..

How long does it take to shift?

I don't have an exact time, but not that long I would say... The spacing between gears is roughly 1/32", so once it's out of one gear, it's already engaging the other.

I assume that's slightly exaggerated, and it doesn't actually engage both gears at the same time?

Wow... nice shifter... is that a airplne servo up top or a motor? Seems to be a lot of gear reduction for the gear-reduction-changer.

Wow... Ludicrous Speed... I feel like watching Spaceballs now...

It's another motor on top. The reasoning for the extra reduction is because just driving the worm gear off the motor wasn't a fast enough shift for us, but with the 1:3 reduction before the worm reduction our shift is much nicer.

On a side note, brownie points if anyone can get the sand-crawler reference...

Let me see if I can get a better pic of the spacing for you... they both don't engage at the same time, but the time from one gear to the next is very short.

I'm assuming you're referring to the incredibly slow Jawa sand-crawlers from Star Wars?
