FedEx recently introduced DexR, a two-armed robot designed to autonomously put packages in delivery trucks like a Tetris puzzle, saving the hassle for the company’s workers. DexR, developed by a California-based startup called Dexterity that builds robotic systems for warehouse tasks, uses AI in this scenario to stack varying-sized boxes in a way that would also save cargo space.
Loading and unloading packages onto trucks is a more challenging task compared to picking that robots undertake in warehouses because it occurs in a tight space with varying boxes. Of course, the systems can be engineered to reduce that complexity.
Because packages have different sizes, weights, and shapes, it’s difficult for a machine to sort them out. So cameras and LIDAR sensors help the DexR robot distinguish each package, allowing it to arrange the boxes neatly atop each other to form a wall without causing damage. It also reacts accordingly if any packages slip out. The robot is now in the testing phase before being rolled out later on.
Additionally, the robot relies on generative AI to determine how the boxes of different types should stack. The machine also leverages AI to identify and pick up those boxes. However, the system must be crafted through careful engineering. Whenever it adds a box atop the stack, the system uses force-feedback, ensuring the package fits nicely. The sensors and cameras also determine how it looks compared to the current model. The robot would need to change the stacking plan if it finds a discrepancy.
It’s unclear how many DexR robots FedEx plans to deploy, and the company is collecting data to see if they’re reliable. Even then, the robot’s capabilities can be used for other tasks, allowing them to tackle other jobs. While the team is still working to perfect the DexR robot, it could load a truck at the same speed as a skilled worker. So far, FedEx uses Berkshire Grey’s robotic technology to sort parcels in facilities. It has cost the company $200 million to purchase systems.
However, workers have already started worrying about losing their jobs to robots due to AI advancements. For instance, technological trends contributed to the US autoworker strike, which also includes electrification and autonomous vehicles.
