Thank you, thats is the same points i brought up.

Uh, neither? Our team has had bad experiences with both; a scissor lift in 2002 had trouble supporting any kind of weight at all (similarly, team 898 from next door to us tried it in 2004 and had to toss it when it couldn't support weight), and a double jointed arm in 2003 could not even support its own weight and destroyed itself (part of this was due to a miscalculation in the strain on sprockets, but regardless it still wouldn't have gone well).

We're convinced the way to go is a combination elevator/arm like we used in 2005; we've already decided we'll be doing it for this year's bot, it's just a question of exactly how they are given power to move that is up now.
