Autonomous mobile robot benefits and innovations

Autonomous mobile robots (AMRs) are one of the latest and most innovative automation solutions on the market and have a greater degree of autonomy, which make them ideal for Lean operations.

05/20/2018


Robots in the industrial sector are quickly evolving from powerful, stationary machines into sophisticated, mobile platforms to address a broader range of automation needs. Autonomous mobile robots (AMRs) are one of the latest and most innovative automation solutions on the market.

AMRs differ from automated guided vehicles (AGVs) by their degree of autonomy; AMRs are more independent than AGVs. AMRs will be an important part of lean operations in a wide range of industrial settings once they are widely deployed, as they are built to address specific challenges in typical industrial environments.

Typical AGVs need some form of external guidance such as permanent wires, magnetic strips, or sensors embedded in the floor. This creates a rigid system that's difficult and expensive to adjust as production needs change, which is the main obstacle AMRs aim to overcome.

AMRs are much more capable of navigating dynamic environments. They require little external input to do so, which is an important capability. Industrial environments like construction sites are inherently dynamic. Manufacturing facilities are becoming more dynamic as they pursue Leaner operations. Robots that can operate within these environments will have major commercial potential, introducing process automation without hindering the need for frequent changes in the production environment.

One of the latest innovations in AMRs is the inclusion of onboard intelligence systems. These come in a variety of formats but differentiate AMRs from AGVs. Many AMRs can learn their surroundings either by having a blueprint uploaded, or by having the AMRs drive around and develop their own map. This type of autonomy allows them to quickly adapt to just about any industrial environment.

Another major innovation in AMRs is their computer vision capabilities. Most AMRs are equipped with an array of complex sensors to detect objects around them. The ability to accurately perceive a dynamic environment in real-time is incredibly difficult, but it's what make AMRs so valuable in a constantly shifting industrial setting.

AMRs are an important robotic innovation that supports the constant pursuit of productivity in the industrial sector. AMRs have great commercial potential and are likely to be deployed in a wide range of settings.
