can someone please explain how the 254 2011 design works http://team254.com/first/2011frc/

Pay specific attention to the pages on telescoping lifts. The 254 example is, AFAIK, of the continuous rigging variety. :slight_smile:

wait how do they keep it inside the same bar?

I would highly recommend not attempting a 254 style construction elevator. There are much simpler ways and designs.

If you want to know about cascade-rigged elevators, I suggest watching some of the videos here: http://www.greybots.com/videos.html

I second this. We did last year and learned our lesson well.

I don think we┬┤re actually using it on our robot, I was just wondering how the in bar design works for a multi-stage lift.
