L7 · Best for
Precision industrial tasks: sorting, scanning, screw-driving, and delicate operations like tearing paper towels and pulling curtains alongside heavy material handling
B2 · Best for
Power grid and petrochemical facility inspections, where thermal imaging and gas sensing payloads and all-terrain mobility justify cost.
Final judgment
If immediate deployment is the priority, choose B2. If the goal is to be ready when L7's capabilities mature, track it.
