Automated guided vehicles (AGV) or mobile robots are types of guided robotic systems that are not bounded by a fixed range of motion. They are generally used in logistics.
Navigation is the ability of the guided vehicle or mobile robot to determine its location and know autonomously the direction of where it would proceed while avoiding collisions and unsafe conditions.
Integrating the processes of perception, localization, path planning, and motion control creates the whole navigation system. Common navigation systems are physical guides, anchoring points, laser guides, and GPS.
Locomotion is the ability of AGVs to propel themselves from one point to another. The common mode of locomotion is through rolling components or wheels which are widely used due to their simplicity and minimal friction loss.
