The sprocket might be fine, but in this particular photo I would have some very real safety concerns about things (such as human hands) getting caught in the chain.

I'm sure that a guard for the chain and/or a robot exterior that inhibits access have been removed for clarity, but just a friendly reminder that just because a part is legal, the application of that part will not neccesarily pass tech if it is deemed to be unsafe.
