![]() ![]() In the case of AMRs, the navigational choice depends mainly on the operational environment. In these systems navigation is provided by beacons or scannable images (e.g., 3D barcodes) along the vehicles route. It’s common for a map to be integrated within the AGV control system, with pre-planned and plotted routes. The autonomous navigation technologies can be fitted either during or after production.ĪVG navigation technologies may feature an electro-magnetic tape, wire (embedded in the facilities floor), or beacon system (utilising radio, vision or lasers). While most AMRs are produced by new market entrants, established tow and fork truck manufacturers offer ‘autonomy-ready’ vehicles. This is because they have typically been built from the ‘ground up’, allowing for the integration of navigation technologies and different payloads (such as conveyors or industrial robot arms). The flat top ARM design has become most common over the last decade. Flat top (also known as mouse) - moves underneath and lifts a pallet, shelf or trolley before moving or carrying an industrial manipulator.Forked – almost identical to a traditional pallet/reach/forklift truck, but unmanned.Tow truck – which pulls a cart or trolley behind it.Original AGV and AMR designs were based on adapted forklift truck platforms, with many of the traditional characteristics being retained to this day.Īs interest in the AGV/AMR market has grown these three types have become common: While AMRs offer a high level of flexibility, there’s the potential for workflows to be delayed where obstacles have to be navigated. While AMRs have the benefit of being able to re-plan routes if there are obstructions, AGVs can’t do this without human intervention.ĪGVs are generally considered to be more predictable than AMRs, with known arrival times and routes. ![]() ![]() This means that AMRs autonomously map and plan their own routes for maximum safety. They are often kept separate from humans for reasons of safety.Īutonomous Mobile Robots (also known as Industrial Mobile Robots) differ in their free navigation of workspaces. Initially used in warehousing and logistics, such vehicles have also come to replace forklift trucks in factory settings. These ensure that the vehicle stays on a set path. The key characteristic of an AGV is that it’s a guided vehicle, with information being transferred via marked floor lines/wires, radio beacons, camera systems or lasers. ![]()
