Why it matters: the robot crosses a level change up to 10 mm. Beyond that, an expansion joint, a doorway or a poorly seated plate stops the mission or jolts the load.
How we measure it: we walk each planned route and record every threshold with a tape measure, including ones your teams no longer notice.
If the limit is exceeded: a light ramp placed on either side of the threshold solves most cases, with no construction work.
Why it matters: the wheels cross a gap up to 35 mm—a drainage channel, a grate or a recessed rail. Wider, and it risks catching the wheel.
How we measure it: we survey grates, channels and door rails along the route, in both directions of travel.
If the limit is exceeded: a cover plate placed over the crossed section is usually enough, or the route goes around the obstacle.
Why it matters: loaded with 2,000 kg, the autonomous pallet truck climbs up to 3°, about 5%. Empty, it climbs up to 8°. A ramp that's too steep rules out a loaded route, without ruling out the project.
How we measure it: with an inclinometer, on every ramp, dock and camber along the loaded route.
If the limit is exceeded: we propose an alternative route, sometimes longer but passable, or reserve the ramp for empty runs.
Why it matters: the robot picks up a pallet at 90° in a 2 m aisle. It self-corrects an offset pallet up to 15 cm or one rotated up to 15°, but aisle width remains the condition for the maneuver.
How we measure it: we record the actual usable width, between posts, racking and drop-off zones, not the theoretical figure on a floor plan.
If width is lacking: shifting the pickup a few slots, reorienting pallets, or reversing a traffic direction is often enough.
