Re: Question about worm gears

Now I know it would be really helpful if I could remember what team it was or where to find a picture of their robot... but perhaps someone will recognize the team I am talking about and post that info here.

I don't remember their drive system as being either devastatingly effective, or terribly problematic... I just remember it being cool because it was something different, and quite elegantly designed.
The team was 1425. I didn't see any info on their website about their worm gears, but they do have a forum. There are also a few people that read chiefdelphi, but haven't been active in a month or so.

Here's a picture of their worm gear and of their whole robot.
