This is extremely useful because it gives the robot the ability to know where it is going without the use of a sensory infrastructure, while also allowing it to be taught a different map very easily. After collecting all of the data from the plant floor, it then creates a virtual map of the entire plant floor. Typically, when a mobile robot is first installed, the robot is jogged around the plant while the sensors are running. Commonly used sensors are area scanners, diffuse laser sensors, and cameras. A mobile robot uses sensing components that are built onboard the machine in order to detect the environment. Instead of using an infrastructure (wires, reflective markers, etc.), all of the sensing and path planning is done onboard by the robot. However, the way it goes about it is completely different. When the machine is ready to be unloaded, a truck-sized AGV goes and picks up all of the parts at once and drives itself back to home.Ī mobile robot’s task is very similar to that of an AGV’s: get my stuff from point A to point B. I have seen cases where the entire plant floor is mapped out by embedded wires in the ground. By sensing the landmarks, the vehicle can then triangulate its position.ĪGVs can be very impressive. It senses retroreflective landmarks strategically placed throughout the plant. Laser guidance uses a laser emitter-receiver.This is key because it helps deal with the inevitable drift of the system. Magnets are then placed in strategic locations to reset the system.
