Nope, there's only one elevator, and that's exclusive to stacking. Also, the elevator is really short: it can lift up to the second tote level; after all, stacking really only occurs at that level.
To answer the second question, the robot has a four-bar linkage arm powered by 2 BAG motors (okay is there like a thread about BAGs vs. 775s somewhere?). That lowers down and actuates a pneumatic claw to grab the bin. I do not need a pivot for the claw, because the geometry of the four-bar automatically controls the angle of the claw to be horizontal with the ground.
Robotics competitions take place in the same "perfect" environment that basic physics equations take place in. :rolleyes: - Branden Ghena [more]
