sorry for bumping this old thread.
This is my first post, but since my dark ages ended a year ago I am a frequent reader.
As it happens, I stumbled across this thread and the walker inspired me to transform it into some kind of contraption I want to share with you.

The walker is attatched to a trussed beam connecting loading and unloading station.

The loading-station is driven by a M-motor. Once it gets activatet it first rotates the container-carrier and then transfers the power to the conveyor.

The unloading-station is driven by a L-motor and first rotates up and then the carrier in order to empty the containers.
The mechanisms by themselfs run reliable but getting the containers into them, out of them and locking them is the tricky part.
Unfortunately I feel its a bit over-engineered and I ran out of skill and patience and am going to disassamble it soon. It only does two to three rounds until getting stuck or dropping a containers and balls will be everywhere.
Still I wanted to share it with you, maybe it will be of use to someone.
