| Deployment fit |
|---|
| Best for | - Indoor floors, covered yards, and dry loading docks
- Short loops with frequent docking
- Proof-of-concept pilots and budget-led first deployments
| - Long paved perimeters, logistics yards, and campuses
- Sites that mix ramps, stairs, and open ground
- Patrols that need distance per charge
| - Substations, plants, tunnels, and outdoor perimeters
- Night and low-light routes with a thermal payload
- 24/7 fleets that dock and recharge without a hand on them
| - Indoor and sheltered industrial inspection rounds
- Thermal and gauge reading on a fixed, repeatable route
- Sites that want the robot docking and running itself between missions
