our arm is ran off of a pulley system they are all on the inside "protected" from harm and mounted on custom pillow blocks. the drum for the cable has 2 sides one for extension and one for retraction but the drum is surrounded by washers " counterweight" i know it sounds crazy adding weight but we were around 119.8 we have one nippon desco motor turning the drum.
and at saint louis almost nobody knew how our arm extended nobody really asked that i can remember
