I had a similar idea once, an autonomous miniature meth lab. Since it operates as a conveyor belt process and won't require a human, it would save on a lot of space because components could be packed tightly together. So you could have ten or fifteen of these autonomous meth labs creating batches of high purity and consistency.
Also a similar idea for growing weed, in a cabinet, using a process I called Sow and Forgo, as in sow your weed seed and forgo any further involvement in the process; the robot does all the rest.
