A mobile robot is a self-driven machine powered by advanced AIoT hardware and sophisticated software programming. Utilizing artificial intelligence, IoT, and wireless detection, these robots can identify their surroundings and navigate their environment autonomously.
Introduction to Autonomous Mobile Robots
Autonomous mobile robots like AGV or AMR are designed to move independently, reacting to input data from their environment. They are a sophisticated blend of AIoT hardware and software. Equipped with sensors like cameras, LiDAR, and ultrasonic sensors, AMRs perceive their surroundings, creating a digital map of their environment. Advanced algorithms enable AMRs to process sensory data, make real-time decisions, and plan their movements accordingly. Leveraging technologies like SLAM, AMRs can build and update maps of their environment while simultaneously determining their position within it.
Types of Mobile Robots
Mobile robots can be categorized into two main types based on their guidance systems: autonomous and non-autonomous (guided) mobile robots.
Automated Guided Vehicles (AGVs)
AGVs require some fixed paths or external guidance to navigate, such as sensors installed in their environment. These systems can be costly to deploy and complex to adjust as needs change.
Autonomous Mobile Robots (AMRs)
In contrast, AMRs possess an inherent ability to navigate and make decisions independently. They are designed to move and explore their surroundings without any external direction, and without the need for physical infrastructure.
The first general-purpose mobile robot to move around autonomously was Shakey, developed in 1970 by SRI International. Shakey could reason about its actions, allowing it to receive general commands and figure out the necessary steps to accomplish the given task. Shakey laid the groundwork for today’s sophisticated AMRs.
