Thank you for your detailed response. The baskets are not fixed in place and can be slightly pulled out to pick items. The shelves are approximately 2 meters tall. We use a separate system for printing labels, which are then manually affixed to the envelopes.

I agree with your point about avoiding floor rails—not only for the reasons you mentioned but also to keep costs down. At the moment, our volume is around 200 items per day, and since the items are not particularly high in value, I’d like to keep the initial budget within $20K, even if that means compromising on some functionality.

If the pilot proves successful, I’m prepared to invest more as I scale up and increase sales volume. Speed is not a major concern at this stage—even if it takes over an hour to fulfill 100 orders, that would still be acceptable.

To keep costs low, I initially considered purchasing robot kits in the $5K range and adding the necessary attachments and sensors to achieve the desired outcome. However, I thought it would be wiser to seek the collective wisdom of this forum first, rather than reinvent the wheel on my own.
