I work on a similar type of application (AI connected to a robot arm that sorts recycling). This looks pretty efficient for a few reasons.
- Consistent lighting is crucial for the most efficient AI. Full overhead enclosure makes this way easier
- Gantry style robot is MUCH lighter and easier to repair than both a 6-axis arm or even a delta robot. It's also likely an order of magnitude cheaper than other options
- Gantry robot also makes it pretty modular if they need to modify for different crop widths
