AGV can be guided through different guidance systems
Laser guidance system
Often referred to as LGVs (Laser Guided Vehicle), laser-guided vehicles use a number of reflectors located on walls/beams along the route followed by the vehicles, which allow for accurately calculating their position. Physical devices along the route such as wires, magnets, painted stripes, etc. are unnecessary. Routes and objectives can be simply and rapidly modified via software to ensure maximum flexibility for company logistics and whenever the system needs upgrading.
