High-speed magnetic grid navigation combining low-cost floor-embedded magnetic markers with tactical inertial dead-reckoning.
RoboticAGV mounts a 16-channel linear Hall-effect sensor bar beneath the chassis, measuring magnetic flux deviations across floor-embedded magnetic tape with ±0.5 mm lateral resolution at speeds up to 3.0 m/s.
In trackless zones, discrete cylindrical neodymium magnets are flush-mounted into the concrete slab on 1-meter grids. The vehicle navigates via inertial odometry, resetting cumulative drift to absolute zero with every magnetic marker encounter.
