A cobot, or collaborative robot, is a robot intended for direct human robot interaction within a shared space, or where humans and robots work in close proximity. The cobot and human worker normally complete tasks independently or sequentially.
The definition of an Autonomous Mobile Robot (AMR) is a robot that travels in X and Y horizontally but not vertically and travels freely along the warehouse floor with safeguards for potentially interacting with human traffic. It is generally fitted with attachments to facilitate single, multi or batch order picking for both goods-to-person and person-to-goods picking. It moves through its environment without being supervised directly by an operator or limited to a fixed path.
Automatic Guided Vehicles (AGVs), including carts, lift trucks and purpose-built carriers that are computer-controlled wheel-based load carriers (normally battery powered) that run on a plant or warehouse floor (or, if outdoors, on a paved surface). Most AGVs follow predefined paths, although there may be areas of the plant or warehouse where they have more freedom.
