It's pretty straightforward, and came in at about 16 lbs, including a CIM.
Four-start screw (3/8" x 3'), Banebots 4:1 transmission, flexible-but-not-too-flexible shaft coupling, a thrust bearing, some aluminum tubing, some extruded aluminum and delrin sliders, some gubbins to hold it all together, two limit switches, a ratchet-like catch on the bottom, and a big ol' hook on top.
We built our robot so that everything but the mecanum drive was completely modular -- even our electronics are held on by velcro and nothing else -- and came up with five or six lift prototypes. This was the one that worked best for us, so we bolted it on top (literally).
It's a shame we never fell over, though. That righter took some effort to make just right, and we never used it. (Then again, if we fall over fast enough, we literally bounce right back to our 'feet'... Making this robot a bit like our team, come to think of it!)
