A magnetic tape or a colored reflective tape (or a strip painted with reflective paint) stuck to the floor is used to mark the route. The vehicles are equipped with magnetic or optical sensors that detect the presence of the tape and allow the vehicle to be driven along the route marked with the tape.

+ very durable, can be installed in the floor

– route complexity limited to route selection – straight – right / left

+ possibility to significantly complicate the route, i.e. choosing straight left / right + red / blue / green. Ease of location, speed of modification.

– susceptibility to damage and dirt

+ unlimited possibilities of building routes

– range limitations
