Automated Guided Vehicles (AGVs) are also known by other names including LGV (Laser-Guided Vehicle), SGV (Self-Guided Vehicle), as well as Guided Carts, Mobile Robots, Driverless Vehicles or Autonomous Vehicles and similar name variations. All can be the same or different in vehicle body structure, but all will have one (sometimes two!) methods of automatic navigation based on these technologies:

AGV Laser NavigationLaser. A series of reflective tape points are mounted on surrounding walls, poles (or racking and other infrastructure). A laser sensor within a rotating turret is mounted atop the AGV. Laser is constantly transmitted & received by the same sensor. The angle and (sometimes) distance to any reflectors that are in line-of-sight are automatically calculated and triangulated to give the current position of the AGV. The AGV compares this to the known map and path, then steering is adjusted to keep on track, with this constantly updated positioning.

AGV Contour Range NavigationRange / Contour. Using one or more on-board laser sensors, the technology detects and identifies walls, columns and racks (eg: within a warehouse). Using these fixed references, it can position itself in real time and navigate to destinations. Working particularly well in corridor environments, this also makes it an ideal technology for Hospital AGV's.

AGV Magnetic Spot NavigationMagnetic Spot. Using a series of small cylindrical magnets embedded in the floor at known positions, the AGV records and projects its travel direction and distance while comparing and correcting over these regular reference check-points.

AGV Tape or Wire NavigationOptical or Magnetic Tapes and Wires. These older technologies still find applications today. Guidance floor Tapes are initially less expensive and easy to install or reposition (unlike Wire guidance that must be literally cut & embedded into the floor), but tapes are unsuitable for high traffic areas where they may become damaged or dirty. Where flexibility of vehicle paths is not important, inductive or radio-transmissive wires can be a simple and reliable solution.
