Elevation wrist


Just wondering how you guys do that stuff with the wrist of a grabber bot and put it to a higher elevation. In science olympiad last year, i saw a kid with a tall pillar and a wrist attatched there which i have no clue how he did. But, i do know it had effectively worked in order for him to load, ping pong balls, legos, tennis balls and D-Cell batteries in to a coffee can.

He used these two tall metal rods that were shaped like a little L. Thanks for your help guys.
