Amazon is testing out a new class of AI-powered, self-navigating robots in their fulfillment centers. Unlike their earlier counterparts, these next-generation robots will be able to roam freely, helping associates with tasks such as transporting oversized and bulky items around harder-to-navigate parts of the facility floors. 

The e-commerce leader uses around 500,000 robots in its fulfillment centers, but their current robots are restricted in their movements, sticking to a grid of markers enabled by cloud-based algorithms. 

What sets the new robots apart, Amazon says, are their capacity to not only move without restriction, but their “semantic  understanding” – that is, the ability to make sense of the three-dimensional structure of their environment and distinguish the behaviors of objects within it. Using LIDAR (light detection and ranging) and computer vision technology, the robots collect data, map out their surroundings, and can learn to avoid both fixed and moving obstacles. Through this, the robots can make sense of ever-changing, crowded settings such as fulfillment centers. 

For now, Amazon has rolled out these newer robots in select FCs and assigned them a limited number of tasks. The goal is to integrate the robots safely and seamlessly into the everyday operations of Amazon fulfillment center associates, the company said.

For decades researchers have worked to design robotic hands that mimic the dexterity of human hands in the ways they grasp and manipulate objects. However, these earlier robotic hands have not been able to withstand the physical impacts that can occur in unstructured environments. A research team has now developed a compact robotic finger for dexterous hands, while also being capable of withstanding physical impacts in its working environment.

The team of researchers from Harbin University of Technology (China) published their work in the journal Frontiers of Mechanical Engineering on October 14, 2022.

Robots often work in environments that are unpredictable and sometimes unsafe. Physical collisions cannot be avoided when multi-fingered robotic hands are required to work in unstructured environments, such as settings where obstacles move quickly or the robot is required to interact with humans or other robots. 

The energy generated by these impacts can damage the hardware systems of the robotic hands. The current dexterous hands are rigid and therefore can be easily damaged by physical impacts and collisions. There is a need for robots equipped with sturdy, dexterous hands that can withstand physical impacts. The research team worked to create a robotic finger that could mimic the human finger in dexterity and also in its ability to absorb and withstand physical impacts.
