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 traditional definition for an 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. Generally fitted with attachments to facilitate single, multi- or batch order picking for both goods-to-person and person-to-goods picking.
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.
