Autonomous machines and self-driving cars receive a lot of media attention and the buzz around the topic is big. The terminology is not always very clear \u2013 what is the difference between a robot and an autonomous machine \u2013 or is there any? Are AGVs and IAVs the same thing?<\/strong><\/p>\n

This blog post covers some of the most common terms around the topic. Here we go:<\/p>\n

AGV<\/strong>. Automated Guided Vehicle<\/em> or Automatic Guided Vehicle<\/em> is a machine used for material handling operations in warehouses and factories. Typical AGVs move automatically pallets, raw materials, bins, carts, containers etc. from one place to another without direct human operation. Older models follow the marked lines or wires on the floor, newer AGV systems use cameras, magnets, lidars or radio waves for navigation.<\/p>\n

AMR<\/strong>. Sometimes term AMR \u2013 Autonomous Mobile Robot<\/em> \u2013 is used to differentiate traditional AGVs from more intelligent material handling machines. AMRs are not dependent on physical wires or floor markings to navigate. They have advanced sensor systems and capability to dynamically plan their routes according to the surrounding environment and traffic situation. Path planning and decision making can take place in the AMRs on-board computer or in the server controlling the AMR fleet. Anyway, many modern AGV systems have similar capabilities than AMRs, so the difference between AGVs and AMRs is not very clear.<\/p>\n

Autonomous<\/strong> machine<\/strong>. Autonomous Machine can sense its environment and adapt its operation accordingly. Sometimes terms automatic<\/strong> and autonomous<\/strong> are used interchangeably, but the terms have a difference. While automatic machine performs its tasks according to the pre-defined rules, autonomous machine can learn from its surroundings and decide independently how to act.<\/p>\n

Autonomous Vehicle<\/strong>. Autonomous vehicle (or AV) is often used as a synonym for an autonomous car – a car that can navigate and drive without human operator. Autonomous Vehicles cover also wider set of machines than just passenger cars. Autonomous Vehicles are used also for example in logistics for autonomous material handling operations. Vehicle autonomy level is defined at six levels, see below the term Level of autonomy.<\/p>\n

Cobot<\/strong> is an acronym for collaborative robot. Typically industrial robots work on the restricted areas, where humans are not allowed to go while robot is working. Cobots can instead work simultaneously with humans in the same place. Safety is taken care by software and sensors or by limiting the speed and force of the cobot.<\/p>\n

Fleet. <\/strong>Fleet in this context is a set of robots working in the same location. Robot fleet is usually managed by Fleet Controller<\/strong> or Fleet management system<\/strong>.<\/p>\n

Fleet Management System <\/strong>is a software system controlling the robot fleet. Fleet management system monitors the position, battery level and condition of individual robots, receives tasks from ERP or WMS (Warehouse Management System), schedules the tasks and allocates them to the robots. Fleet management system plans routes, detects possible bottlenecks and optimizes the operation of the entire robot fleet.<\/p>\n

IAV<\/strong>. Industrial Autonomous Vehicle<\/em> is an autonomous machine used in industry. IAV term is often used as a synonym for an autonomous machine.<\/p>\n

Level of autonomy.<\/strong> \u00a0Standard developing organization SAE International has defined six levels of vehicle automation:<\/p>\n
