I'm curious about your arm. It looks pretty beefy and reliable. Those are some big mamma-jamma sprockets on there, what kind of motor/reduction are you using? Also, does your arm extend? It looks like you have those 80/20 sliding things on there. (Don't know their technical name and even if I did I'd be hard pressed to remember at this hour
)
EDIT: Oops I remembered I read it does extend, you are using the globe for that and the van door for your arm
Sorry, sleepy. Still curious about the reduction and 80/20 stuff though
