So quick question, let's say you had an elevator travelling 6 feet, but you wanted your end effector to travel only 5 inches. Would you do that with a separate motor or with something "piggybacking" off the elevator lift and "stepping down" the movement so that it actuates the 5 inches while the elevator actuates the 6 feet? Or just use a slide and another device for the last motion? Think something in the terms that you want to place totes with the elevator, and use the last motion when you place a container on top.
And yes I think this is year where there will be a lot of elevators....
